It has to do with gastric distention, or the stretching of the stomach after we eat a large amount of food.
|

Duker Freuman explains that bloating is a pressure that's just shy of pain, and it can also present as a visible distention of the stomach.
|
|
The feeling of my mouth stuffed with food and the over-distention of my stomach offered some kind of haptic feedback I still struggle to explain.
|
|
"It's that feeling of over-fullness and discomfort in the digestive tract, or it's a visible distention of your abdomen, which increases the size of your stomach," Freuman added.

The clinical signs of these forms of colic are generally mild, transient, and respond well to spasmolytic medications, such as buscopan, and analgesics. Gas colics usually self- correct, but there is the risk of subsequent torsion (volvulus) or displacement of the bowel due to gas distention, which causes this affected piece of bowel to rise upward in the abdomen. Abdominal distention may occasionally be seen in adult horses in the flank region, if the cecum or large colon is affected. Foals, however, may show signs of gas within the small intestines with severe abdominal distention.
|
|
Water was once used routinely, however, problems with water intoxication and hemolysis discontinued its use by 1990. Each of these distention fluids is associated with unique physiological changes that should be considered when selecting a distention fluid. Glucose is contraindicated in patients with glucose intolerance. Sorbitol metabolizes to fructose in the liver and is contraindicated if a patient has fructose malabsorption.
|
|
Gas distention usually produces mild clinical signs, but in some cases leads to severe signs due to pressure and tension on the mesentery. Simple obstructions often present with a slightly elevated heart rate (<60 bpm) but normal CRT and mucous membrane color. Strangulating obstructions are usually extremely painful, and the horse may have abdominal distention, congested mucous membranes, altered capillary refill time, and other signs of endotoxemia.
|
|
Although lung distention has been described as a classic symptom, hypoplasia or complete aplasia of the lungs can also occur, in an estimated 26% of cases. In some cases, normal lung development was also reported in neonates with tracheal agenesis. The abnormal development of the foetus’ lungs leads to cardiovascular abnormalities. Distention of the lungs results in a compressed and displaced heart, hindering the normal growth and development of the organ.
|
|
Nasogastric intubation, a mainstay of colic management, is often repeated multiple times until resolution of clinical signs, both as a method of gastric reflux removal and as a way to directly administer fluids and medication into the stomach. Reflux must be removed periodically to prevent distention and possible rupture of the stomach, and to track reflux production, which aids in monitoring the progression of the colic. Its use is especially important in the case of strangulating obstruction or enteritis, since both of these cause excessive secretion of fluid into the intestine, leading to fluid back-up and distention of the stomach. Nasogastric intubation also has the benefit of providing pain relief resulting from gastric distention.
|
|
Physical findings suggestive of volume depletion include dry mucous membranes, decreased skin turgor, and low jugular venous distention. Tachycardia and hypotension can be seen along with decreased urinary output.
|
|
Abdominal percussion ("pinging") can sometimes be used to determine if there is gas distention in the bowel. This may be useful to help determine the need for trocarization, either of the cecum or the colon.
|
|
Josef Breuer and Ewald Hering reported in 1868 that a maintained distention of the lungs of anesthetized animals decreased the frequency of the inspiratory effort or caused a transient apnea. The stimulus was therefore pulmonary inflation.
|
|
Lifestyle changes may include stopping smoking and reducing stress. Medications may include ibuprofen, pentosan polysulfate, or amitriptyline. Procedures may include bladder distention, nerve stimulation, or surgery. Pelvic floor exercises and long term antibiotics are not recommended.

277x277px The classic in-utero symptoms of tracheal agenesis are an absence of the trachea leading to congenital high airway obstruction syndrome, lung distention, polyhydramnios, heart malformations, heart displacement and hydrops fetalis. Other congenital malformations such as genitourinary, gastrointestinal and musculoskeletal anomalies are common and occur in 80% of the reported cases. Tracheal agenesis may lead to a distention of the foetus’ lung due to a build- up of pulmonary fluid within them. In this case, ultrasound scans show bilaterally enlarged and homogeneously echogenic lungs as well as the inversion of both hemidiaphragms.

Hope reported in 1937 on the use of laparoscopy to diagnose ectopic pregnancy. In 1944, Raoul Palmer placed his patients in the Trendelenburg position after gaseous distention of the abdomen and thus was able to reliably perform gynecologic laparoscopy.
|
|
Polydactyly and heart disease are associated with this condition. Diagnosis is challenging because symptoms also occur in a variety of other syndromes. Secretions can build up and extend as far as the uterus and abdomen. Mucometrocolpos can sometimes cause abdominal distention.
|
|
However, obstructions that have been present for some time may present with thickened walls and distention of the intestine. DPJ can only be definitively diagnosed during surgery or at necropsy, when its gross appearance of the small intestine may be evaluated.
|
|
How abdominal distension develops is not fully understood and several causes have been proposed. A buildup in fat around the abdominal cavity, heavy constipation, habitual lordosis, and other causes may produce the appearance of a distended abdomen, and the resulting swelling can remain for months. After women with false pregnancy are placed under anesthesia, or are successfully persuaded that they are not pregnant, the distention promptly disappears, indicating that the proposed mechanisms are supplementary factors behind, but not the ultimate causes of, abdominal swelling. Manipulation of abdominal wall muscles, such as the diaphragm, is the most likely contributor to abdominal distention.

The tuber cinereum is an inferior distention of the floor of the third ventricle; the conical hollow formed by the distention (a continuation of the ventricle itself), is known as the infundibulum (funnel). Thus, the tuber cinereum is anteriorly continuous with the lamina terminalis, while laterally it is continuous with the anterior perforated substances of the hypothalamus. The inferior end adjoins the posterior lobe of the pituitary gland. Capillaries of the tuber cinereum are specialized and confluent to enable rapid communication via brain- or blood-borne factors between compartments of the tuber, a capillary system described as the hypophyseal portal system.
|
|
Traumatic asphyxia is characterized by cyanosis in the upper extremities, neck, and head as well as petechiae in the conjunctiva. Patients can also display jugular venous distention and facial edema. Associated injuries include pulmonary contusion, myocardial contusion, hemo/pneumothorax, and broken ribs.
|
|
But it can be rather irritating to the colon, causing intense cramping or "griping." Fleet enemas usually causes a bowel movement in 1 to 5 minutes. Known adverse effects. Sorbitol pulls water into the large intestines causing distention, thereby stimulating the normal forward movement of the bowels.
|
|
Distention activates long and myenteric reflexes. This activates the release of acetylcholine, which stimulates the release of more gastric juices. As protein enters the stomach, it binds to hydrogen ions, which raises the pH of the stomach. Inhibition of gastrin and gastric acid secretion is lifted.
|
|
The greatest sign of improvement is lessening of abdominal distention. Side effects in dogs are uncommon, but they include vomiting, diarrhea, diminished hearing, salivation, decreased weight and behavioral changes such as hyperactivity, listlessness, disorientation, and repetitive motions. Selegiline does not appear to have a clinical effect on horses.
|
|
Vital signs may disclose low- grade fever, tachypnea, tachycardia, and hypotension. Inspect the skin for jaundice. Assess the abdomen for distention, tenderness, discoloration, and diminished bowel sounds. Tests and procedures used to diagnose pancreatic disorders include laboratory analyses of blood, urine, stool, and pancreatic fluid, and imaging studies.
|
|
Patients are seen with a cyanotic discoloration of the shoulder skin and neck and face, jugular distention, bulging of the eyeballs, and swelling of the tongue and lips. The latter two are resultants of edema, caused by excessive blood accumulating the veins of the head and neck and venous stasis.
|
|
The most common signs used for diagnosis are abdominal distention and discomfort, generalized fatigue, loss of appetite and secondary anemia. The most important clinical marker for HBL is serum alpha-fetoprotein (AFP), except in the case of some rare variants of HBL and hepatocellular carcinoma that exhibit lower AFP levels.
|
|
Subtle findings can be missed easily when a single previous examination is reviewed. #The abdominal examination should include a minimum of three views—supine, prone and erect. #On every abdominal examination, evaluate the chest as if you were looking at a chest film. #In obstruction of the lumen, there should be proximal distention.
|
|
OGCTs are relatively difficult to detect and diagnose at an early stage mainly because the symptoms are normally subtle and nonspecific. They become detectable when as they become large, tangible masses. Symptoms include bloating, abdominal distention, ascites, and dyspareunia. In rare cases where the tumor ruptures, acute abdominal pain can be experienced.
|
|
Sinus hyperplasia is the preferential stimulation of the histiocytic (tissues macrophage) compartment. Histological features include distention or engorgement of both subscapular and inatraparenchymal sinuses by benign histiocytes which may be hemophagocytic. Sinus hyperplasia may be associated with non-hematolymphoid malignancy. Other features include presence of white spaces and lymphocytes (large cells) within sinuses.
|
|
The term "hepatojugular reflux" was previously used as it was thought that compression of the liver resulted in "reflux" of blood out of the hepatic sinusoids into the inferior vena cava, thereby elevating right atrial pressure and visualized as jugular venous distention. The exact physiologic mechanism of jugular venous distention with a positive test is much more complex and the commonly accepted term is now "abdominojugular test". In a prospective randomized study involving 86 patients who underwent right and left cardiac catheterization, the abdominojugular test was shown to correlate best with the pulmonary arterial wedge pressure. Furthermore, patients with a positive response had lower left ventricular ejection fractions and stroke volumes, higher left ventricular filling pressure, higher mean pulmonary arterial, and higher right atrial pressures.
|
|
Acute abdomen can be defined as severe, persistent abdominal pain of sudden onset that is likely to require surgical intervention to treat its cause. The pain may frequently be associated with nausea and vomiting, abdominal distention, fever and signs of shock. One of the most common conditions associated with acute abdominal pain is acute appendicitis.
|
|
Most clinical symptoms resulting from Babylonia japonica ingestion, as in the 1965 food-poisoning outbreak, seem to be mediated by ganglion-blockade of nicotinic ACh receptors at various sites; visual impairments and mydriasis due to ciliary ganglion blockade, dry mouth due to submaxillary and otic ganglion blockade, and constipation and abdominal distention due to intestinal intrinsic nerve blockade.
|
|
Any degree of abdominal distension is usually indicative of a condition affecting the large intestines, as distension of structures upstream of here would not be large enough to be visible externally. Abdominal distention may indicate the need for surgical intervention, especially if present with severe signs of colic, high heart rate, congested mucous membranes, or absent gut sounds.
|
|
Malrotation of the entire intestinal tract, or improper folding and bulging of the stomach and intestines, results in bowel obstruction. This impairment leads to vomiting, abdominal distention, mucus and blood in the stool. Patients may also experience abdominal pain. Intestinal malrotation is more commonly identified in patients with right atrial isomerism than in those with left atrial isomerism.
|
|
Environmental factors, such as electrolytes, metabolic products, and temperature are not shown. The determinants of SV during the cardiac cycle are the contractility of the heart muscle, the degree of preload of myocardial distention prior to shortening and the afterload during ejection. Other factors such as electrolytes may be classified as either positive or negative inotropic agents.

One method that the brain uses to evaluate the contents of the gut is through vagal nerve fibers that carry signals between the brain and the gastrointestinal tract (GI tract). Stretch receptors work to inhibit appetite upon distention of the GI tract by sending signals along the vagus nerve afferent pathway and inhibiting the hunger center.Marieb, E., & Marieb, E. (2010). Human anatomy & physiology.

Coeliac disease or celiac disease is a long-term immune disorder that primarily affects the small intestine. Classic symptoms include gastrointestinal problems such as chronic diarrhoea, abdominal distention, malabsorption, loss of appetite, and among children failure to grow normally. This often begins between six months and two years of age. Non-classic symptoms are more common, especially in people older than two years.
|
|
A hydatidiform mole is a pregnancy/conceptus in which the placenta contains grapelike vesicles (small sacs) that are usually visible to the naked eye. The vesicles arise by distention of the chorionic villi by fluid. When inspected under the microscope, hyperplasia of the trophoblastic tissue is noted. If left untreated, a hydatidiform mole will almost always end as a spontaneous abortion (miscarriage).
|
|
Mechanically induced RS is characterized by pressure in the epigastric and left hypochondriac region. Often the pressure is in the fundus of the stomach, esophagus or distention of the bowel. It is believed this leads to elevation of the diaphragm, and secondary displacement of the heart. This reduces the heart's ability to fill and increases the contractility of the heart to maintain homeostasis.
|
|
This loop is called a "sentinel loop." It arises from the body's efforts to localize traumatic or inflammatory lesions. The local distention of that intestinal loop is due to local paralysis and accumulation of gas in the intestinal loop.In acute pancreatitis, the sentinel loop is usually seen in left hypochondrium, while in acute cholecystitis, it is seen in the right hypochondrium.
|
|
The affected person's respiratory rate often increases in the presence of respiratory distress. Pulse oximetry may confirm the presence of too little oxygen reaching the body's tissues, related to any precipitating factors such as pneumonia. Examination of the jugular veins may reveal elevated pressure (jugular venous distention). Examination of the lungs may reveal crackles, which are suggestive of pulmonary edema.

They are sometimes part of a local panch phoron (Bengali five spice) mixture replacing black mustard seeds; the other ingredients are cumin seed, fenugreek seed, fennel seed, and Nigella Seed. In other places, a common use is in pickling or spice mixtures. It is commonly used as an herb for diarrhea, gastritis, loss of appetite, vomiting, abdominal distention, stomachache related to indigestion and also for worm diseases.

Reversible AChE inhibitors play an important role in pharmacological manipulation of the enzyme activity. These inhibitors include compounds with different functional groups (carbamate, quaternary or tertiary ammonium group), and have been applied in the diagnostic and/or treatment of various diseases such as: myasthenia gravis, AD, post-operative ileus, bladder distention, glaucoma, as well as antidote to anticholinergic overdose.Colovic, M. B. (2013). Acetylcholinesterase Inhibitors: Pharmacology and Toxicology.

If defecation occurs too fast, before excess liquid is absorbed, diarrhea may occur. Other associated symptoms can include abdominal bloating, abdominal pain, and abdominal distention. Disorders of the bowel can seriously impact quality of life and daily activities. The causes of functional bowel disorder are multifactorial, and dietary habits such as food intolerance and low fibre diet are considered to be the primary factors.

The classical conditioning paradigm components for the bell and pad method are the following: The unconditioned stimulus (US) is the awakening stimulus or the alarm sound, the unconditioned response (UR) is the awakening response and sphincter contraction, the neutral stimulus (NS) is the feeling produced by bladder distention (feeling of having a full bladder), the conditioned stimulus (CS) is the feeling produced by bladder distention, and the conditioned response (CR) is the awakening response and sphincter contraction. Initially the individual experiences the alarm sounding (activated by urination) (US) eliciting the awakening response and sphincter contraction (UR) to wake up, stop urinating, and travel to the bathroom. After continued pairing of the alarm sound (US) with the feeling of a full bladder (NS), the previous NS of feeling a full bladder becomes the CS and elicits the waking response (CR) of waking up to go use the bathroom and urinate.

The combination of inflammation, reduced blood flow to the appendix and distention of the appendix causes tissue injury and tissue death. If this process is left untreated, the appendix may burst, releasing bacteria into the abdominal cavity, leading to increased complications. The diagnosis of appendicitis is largely based on the person's signs and symptoms. In cases where the diagnosis is unclear, close observation, medical imaging, and laboratory tests can be helpful.
|
|
Constipation, also known as defecatory dysfunction, is the difficulty experienced when passing stools. It is one of the most notable alimentary disorders that affects different age groups in the population. The common constipation is associated with abdominal distention, pain or bloating. Researches revealed that the chronic constipation complied with higher risk of cardiovascular events such as 'coronary heart disease and ischemic stroke', while associating with an increasing risk of mortality.
|
|
Common treatments used for toxic substance ingestions are ineffective, or are even harmful, when implemented in ingestions of caustic substances. Clinical attempts to empty the stomach can cause further injuries. Activated charcoal does not neutralize caustics and can also obscure endoscopic visualization. There is no known clinical benefit of neutralization of the caustic substances; neutralization releases heat as well as causing gaseous distention and vomiting, all of which can worsen injuries.
|
|
Ileus is a cause of colic in horses due to functional obstruction of the intestines. It is most commonly seen in horses postoperatively, especially following colic surgery. Horses experiencing ileus are at risk for gastric rupture due to rapid reflux build-up, and require intense medical management with frequent nasogastric intubation. Ileus may increase adhesion formation, because intestinal segments have more prolonged contact and intestinal distention causes serosal injury and ischemia.

|
In general, lochia has an odor similar to that of normal menstrual fluid. Any offensive odor or change to a greenish color indicates contamination by organisms such as chlamydia or saprophytic. Lochia that is retained within the uterus is known as lochiostasis or lochioschesis, and can result in lochiometra (distention of the uterus - pushing it out of shape). Lochiorrhea describes an excessive flow of lochia and can indicate infection.

|
PHK activates glycogen phosphorylase, which is a key enzyme to mobilize glucose from stored glycogen, through phosphorylation. Glycogen is the polymer storage unit of glucose in the body. When the body requires energy it can use enzymes such as PHK to break down the glycogen into glucose for the body to use. Some symptoms of the disease are altered blood glucose levels, ketoacidosis, growth retardation, or liver distention.
|
|
Cameron lesions are usually found in older adults with anemia symptoms such as fatigue, shortness of breath, and appearing pale. Blood tests in iron deficiency show low hemoglobin, microcytic hypochromic red cells, and low iron-binding saturation and ferritin levels. The lesions are visualized by esophagogastroduodenoscopy. Sometimes the lesions are found when endoscopy is done for other hernia symptoms than anemia such as heartburn, regurgitation, swallowing difficulty, pain or distention.

The scrotum is an anatomical male reproductive structure located caudal to the penis that consists of a suspended dual-chambered sack of skin and smooth muscle. It is present in most terrestrial male mammals. The scrotum contains the external spermatic fascia, testes, epididymis, and ductus deferens. It is a distention of the perineum and carries some abdominal tissues into its cavity including the testicular artery, testicular vein, and pampiniform plexus.
|
|
Early dumping syndrome occurs 10 to 30 minutes after a meal. It results from rapid movement of fluid into the intestine following a sudden addition of a large amount of food from the stomach. The small intestine expands rapidly due to the presence of hypertonic/hyperosmolar contents from the stomach, especially sweet foods. This causes symptoms due to the shift of fluid into the intestinal lumen, with plasma volume contraction and acute intestinal distention.
|
|
Skin administration on rabbits causes death at a LC50 of 268 mg/kg. The NOAEL and LOAEL values for rats are determined at 50 mg/kg for NOAEL and 100 mg/kg for LOAEL. This is based on another sign of methacrylonitrile poisoning; urine retention, with 58% of rats showing bladder distention at an administered dose of 100 mg/kg. Reproductive toxicity was tested in rats, but different outcomes have been reported.
|
|
The symptoms of pseudocyesis are similar to the symptoms of a true pregnancy. Signs of false pregnancy include amenorrhea (missed periods), galactorrhea (flow of milk from breast), breast enlargement, weight gain, abdominal growth, sensations of fetal movement and contractions, nausea and vomiting, changes in the uterus and cervix, and frequent urination. Abdominal distention is the most common symptom. In pseudocyetic abdominal swellings, the abdomen becomes uniformly swollen, and the navel stays inverted.
|
|
Persistent impactions may require fluids administered both intravenously and orally via nasogastric tube, at a rate 2–4 times the maintenance for the animal. Feed is withheld. Horses that do not improve or become very painful, or those that have large amounts of gas distention, are recommended to undergo surgery to remove the impaction via enterotomy of the pelvic flexure. Approximately 95% of horses that undergo medical management, and 58% of surgical cases, survive.
|
|
Clostridial enterocolitis due to infection by Clostridium perfringens is most commonly seen in foals under 3 months of age. Clostridial toxins damage the intestine, leading to dehydration and toxemia. Foals usually present with signs of colic, decreased nursing, abdominal distention, and diarrhea which may contain blood. Diagnosis is made with fecal culture, and while some foals do not require serious intervention, others need IV fluids, antibiotics, and aggressive treatment, and may still die.

The birds nest in colonies and the nest is a thick platform of twigs placed on a low tree. The breeding season varies from October to May. In Tamil Nadu, the breeding season follows the onset of the northeast monsoon. The courtship display of the males involves a distention of the pouch with swinging motions of the head up and down followed by sideways swings followed by the head being held back over the back.
|
|
Post-ablation tubal sterilization syndrome (PATSS) is a rare complication that could occur in patients with prior tubal sterilization following an endometrial ablation procedure. Occult bleeding into the obstructed tubes causes tubal distention and cyclic pelvic pain. Endometrial ablation devices are used for the treatment of menorrhagia due to dysfunctional uterine bleeding. As the popularity of safer, effective, and less invasive procedures increase, the obstetrics and gynecology community will likely see more uncommon adverse events.
|
|
Or it can be caused by osmotic laxatives (which work to alleviate constipation by drawing water into the bowels). In healthy individuals, too much magnesium or vitamin C or undigested lactose can produce osmotic diarrhea and distention of the bowel. A person who has lactose intolerance can have difficulty absorbing lactose after an extraordinarily high intake of dairy products. In persons who have fructose malabsorption, excess fructose intake can also cause diarrhea.
|
|
The abdominal masses can grow to enormous size before being noticed by the patient. The tumors can be felt as hard, round masses by palpating the abdomen. First symptoms of the disease often include abdominal distention, abdominal mass, abdominal or back pain, gastrointestinal obstruction, lack of appetite, ascites, anemia, and cachexia. Other reported symptoms include unknown lumps, thyroid conditions, hormonal conditions, blood clotting, kidney and urological problems, testicle, breast, uterine, vaginal, and ovarian masses.
|
|
However, CO2 gas does not allow the clearing of blood and endometrial debris during the procedure, which could make the imaging visualization difficult. Gas embolism may also arise as a complication. Since the success of the procedure is totally dependent on the quality of the high- resolution video images in front of the surgeon's eyes, CO2 gas is not commonly used as the distention medium. Electrolytic solutions include normal saline and lactated Ringer’s solution.
|
|
Ultrasound is a useful diagnostic tool for colics. Ultrasound provides visualization of the thoracic and abdominal structures, and can sometimes rule out or narrow down a diagnosis. Information that may be gleaned from ultrasonographic findings include the presence of sand, distention, entrapment, strangulation, intussusception, and wall thickening of intestinal loops, as well as diagnose nephrosplenic entrapment, peritonitis, abdominal tumors, and inguinal or scrotal hernias. Abdominal ultrasound requires an experienced operator to accurately diagnose the cause of colic.

|
Once on cardiopulmonary bypass, the patient's heart is stopped (cardioplegia). This can be done with a Y-type cardioplegic infusion catheter placed on the aorta, de-aired and connected to the cardiopulmonary bypass machine. Alternatively, a retrograde cardioplegic cannula can be inserted at the coronary sinus. Some surgeons also opt to place a vent in the left ventricle through the right superior pulmonary vein, because this helps to prevent left ventricular distention before and after cardiac arrest.
|
|
Prune belly syndrome can result in distention and enlargement of internal organs such as the bladder and intestines. Surgery is often required but will not return the organs to a normal size. Bladder reductions have shown that the bladder will again stretch to its previous size due to lack of muscle. Complications may also arise from enlarged/malformed kidneys, which may result in kidney failure and the child's going on dialysis or requiring a kidney transplant.
|
|
In contrast, the gallbladder is more often enlarged and thus more easily palpated in pathologies that cause obstruction of the biliary tree over a more acute, shorter period of time such as pancreatic malignancy, leading to passive distention from back pressure. Ludwig Georg Courvoisier's original observations, published in Germany in 1890, were not originally cited as a 'law', and no mention of malignancy or pain (tenderness) was made. These points are commonly misquoted or confused in the medical literature.
|
|
After the procedure, the patient will be observed and monitored by a qualified individual in the endoscopy room, or a recovery area, until a significant portion of the medication has worn off. Occasionally the patient is left with a mild sore throat, which may respond to saline gargles, or chamomile tea. It may last for weeks or not happen at all. The patient may have a feeling of distention from the insufflated air that was used during the procedure.
|
|
Arterial surgery is only indicated once there is positive confirmation that the arteries are indeed the source of pain. Some migraine sufferers have a visibly distended artery on the temple during an attack, which confirms that the arteries are involved. The distention usually subsides as the pain is controlled by vasoconstrictor drugs (ergots or triptans). In some, this artery is always visible, but it is only when it becomes distended during an attack that it becomes important for diagnosis.

The second, neurological, inhibition mechanism involves mate rejection behavior in which the female flaps and tries to escape. This behavior is stimulated by the neural sensation of bursal distention, which occurs in the presence of a spermatophore. Female and male Edith's checkerspots mating However, even with these prevention mechanisms, females do occasionally mate a second time. In instances where females mate with several males, they lay eggs which have been predominantly fertilized by the sperm of the last male to mate.

Common symptoms of OGCT are bloating, abdominal distention, ascites, and dyspareunia. OGCT is caused mainly due to the formation of malignant cancer cells in the primordial germ cells of the ovary. The exact pathogenesis of OGCTs is still unknown however, various genetic mutations and environmental factors have been identified. OGCTs are commonly found during pregnancy when an adnexal mass is found during a pelvic examination, ultrasound scans show a solid mass in ovary or blood serum test shows elevated alpha-fetoprotein levels.
|
|
This disease is often discovered during surgery for other conditions, e.g., hernia repair, following which an experienced pathologist can confirm the diagnosis. Advanced stages may present as tumors palpable on the abdomen or distention of the belly ("jelly belly" is sometimes used as a slang term for the condition). Due to the rarity of this disease, it is important to obtain an accurate diagnosis so that appropriate treatment may be obtained from a surgical oncologist who specializes in appendix cancer.

|
Eliciting a careful dietary history from patients with suspected malabsorption is therefore crucial. Excessive flatus and abdominal bloating may reflect excessive gas production due to fermentation of unabsorbed carbohydrate, especially among patients with a primary or secondary disaccharidase deficiency, such as lactose intolerance or sucrose intolerance. Malabsorption of dietary nutrients and excessive fluid secretion by inflamed small intestine also contribute to abdominal distention and bloating. Prevalence, severity, and character of abdominal pain vary considerably among the various disease processes associated with intestinal malabsorption.

|
They are sometimes known as autoregulatory vessels since they can dynamically change in diameter to increase or reduce blood flow. Any change in the viscosity of blood (such as due to a change in hematocrit) would also affect the measured vascular resistance. Pulmonary vascular resistance (PVR) also depends on the lung volume, and PVR is lowest at the functional residual capacity (FRC). The highly compliant nature of the pulmonary circulation means that the degree of lung distention has a large effect on PVR.

|
Children with Liddle syndrome are frequently asymptomatic. The first indication of the syndrome often is the incidental finding of hypertension during a routine physical exam. Because this syndrome is rare, it may only be considered by the treating physician after the child's hypertension does not respond to medications for lowering blood pressure. Adults could present with nonspecific symptoms of low blood potassium, which can include weakness, fatigue, palpitations or muscular weakness (shortness of breath, constipation/abdominal distention or exercise intolerance).

|
In some cases draining from a different site from injection (i.e. injecting arterial fluid into the right common carotid artery and draining from the right femoral vein) is referred to as a split (or sometimes cut) injection. In certain cases the embalmer may deem it necessary to perform a restricted cervical injection, which involves injecting the head of the deceased separately from the rest of body. This is done in cases where distention (swelling) has a greater chance of occurring.

|
Signs and symptoms for Bernheim Syndrome are ill-defined and typically follow those of heart failure. Bernheim distinguished Bernheim Syndrome from the typical heart failure presentation via the engorgement of veins due to congestion without evidence of pulmonary congestion. This is evidence of venous blockage without going into pulmonary circulation and is therefore isolated to the right side of the heart. Case presentations of Bernheim Syndrome include symptoms of hypertension, ronchi in the lungs, edema, vein distention, and signs of poor perfusion.

In humans and other mammals, neurons in the PMC send descending excitatory projections to spinally located parasympathetic neurons controlling the detrusor muscle of the bladder and inhibitory interneurons regulating Onuf's nucleus. Additionally, the PMC receives ascending input from the level of the lumbosacral spinal cord. During bladder filling, neurons within the PMC are turned off. However, at a critical level of bladder distention the afferent information arising from mechanoreceptors in the detrusor switches the PMC on and enhances its activity.

The abdominojugular test, also known as abdominojugular reflux (AJR), is a physical examination test useful in diagnosing right ventricle dysfunction, particularly right ventricular failure. AJR is a test for measuring jugular venous pressure (JVP) through the distention of the internal jugular vein. A positive AJR test correlates with the pulmonary artery pressure and thus is a marker for right heart dysfunction, specifically right ventricular failure. Reflux in this context means backflow of the circulatory system and is not to be confused with reflex.

Invasive techniques such as cricothyrotomy must also be available in the event of inability to intubate the trachea by conventional techniques. RSI is mainly used to intubate patients at high risk of aspiration, mostly due to a full stomach as commonly seen in a trauma setting. Bag ventilation causes distention of stomach which can induce vomiting, so this phase must be quick. The patient is given a sedative and paralytic agent, usually midazolam / suxamethonium / propofol and intubation is quickly attempted with minimal or no manual ventilation.

Roughening of the serosal surface of the intestine can occur secondary to peritonitis. Horses that have had gastrointestinal rupture may have gritty feeling and free gas in the abdominal cavity. Surgery is usually suggested if rectal examination finds severe distention of any part of the GI tract, a tight cecum or multiple tight loops of small intestine, or inguinal hernia. However, even if the exact cause can not be determined on rectal, significant abnormal findings without specific diagnosis can indicate the need for surgery.

The primary symptom, hemorrhage, presents differently depending on the degree of injury, with the symptoms of major hemorrhage, shock, abdominal pain, and distention being clinically obvious. Minor hemorrhage often presents as upper left quadrant pain. Patients with unexplained left upper quadrant pain, particularly if there is evidence of hypovolemia or shock, are generally inquired regarding any recent trauma. The primary concern in any splenic trauma is internal hemorrhage, though the exact amount of hemorrhage may be small or large, depending on the nature and degree of injury.

The physiological basis for the RAIR is poorly understood, but it is thought to involve a coordinated response by the internal anal sphincter to rectal distention with recovery of anal pressure from the distal to the proximal sphincter. Mediated by the autonomic nervous system, the afferent limb of this reflex depends upon an intact network of interstitial cells of Cajal in the internal anal sphincter. These cells, which are mediated at least in part by nitric oxide, provide inhibitory innervation of the internal anal sphincter.

During pregnancy, relaxin serves as nature's way of allowing the female pelvis to achieve distention of the birthing canal. Pelvic joint pain in post pregnancy women is thought to be derived from the inability of the stretched out ligaments to return to normal tautness. Women who have delivered large babies or who have had extended labors also are prone to developing chronic sacroiliac joint pain and instability. In some people, the sacroiliac joints reverse the normal concave- convex 'locking' relationship, which can lead to rotational misalignment.

Physicians look for many signs on physical exam that can indicate a potential cause of FTT. For example, findings such as scaling skin, spoon-shaped nails, cheilosis and neuropathy may indicate potential vitamin and mineral deficiencies. Fetal alcohol syndrome (FAS) has also been associated with FTT, and can present with characteristic findings including microcephaly, short palpebral fissures, a smooth philtrum and a thin vermillion border. Malabsorption, due to disorders like Crohn's disease and cystic fibrosis, can present with abdominal distention and hyperactive bowel sounds.

Visual inspection for signs of external trauma such as abrasions, lacerations, contusions, and classic seatbelt sign on the abdomen is helpful. The absence of external visual findings does not exclude intra-abdominal pathology, as up to 20% of patients with intra-abdominal injury may not display these findings upon initial examination. Also, examination on arrival may not reveal severe tenderness, rigidity, or abdominal distention in spite of rupture. Physical examination may also be limited in a patient with altered mental status or distracting injuries.

William Osler Abbott received his A.B. in 1925 and M.D. in 1928 from the University of Pennsylvania. After graduating he worked as an intern in a Hospital of the University of Pennsylvania. From 1931 to 1934 he had experience working part-time with the Department of Pharmacology, and he also co-founded the Miller Abbott Tube in 1934, which is a double lumen drainage intestinal tube for relief of distention. His partner was T. Grier Miller who worked with him from 1930 to 1934 when they founded the Miller Abbott Tube.

The accurate diagnosis of appendicitis is multi-tiered, with the size of the appendix having the strongest positive predictive value, while indirect features can either increase or decrease sensitivity and specificity. A size of over 6 mm is both 95% sensitive and specific for appendicitis. However, because the appendix can be filled with fecal material, causing intraluminal distention, this criterion has shown limited utility in more recent meta- analyses. This is as opposed to ultrasound, in which the wall of the appendix can be more easily distinguished from intraluminal feces.

There are factors that can predispose women to vaginal injury during consensual sex. These things include: first sexual experience, pregnancy, vigorous penetration, vaginal atrophy and spasm, previous operation or radiation therapy, disproportionate genitalia, penile ornamentation, and congenital anomalies. During vaginal intercourse in the missionary position with legs tilted all the way back, the penis reaches its deepest penetration and the extreme rotation of the uterus leads to hyper distention of the vaginal wall, which in some cases can cause it to rupture. This position is the most likely position for vaginal laceration.

Treatment includes fluid therapy and analgesics, but surgery is indicated if there is severe distention of the cecum or if medical therapy does not improve the situation. Surgery includes typhlotomy, and although cecal bypass has been performed in the past to prevent reoccurrence, a recent study suggests it is not necessary.Plummer AE, Rakestraw PC, Hardy J, Lee RM: Outcomes of medical and surgical treatment of cecal impaction in horses: 114 cases (1999-2004), J Am Vet Med Assoc 231:1378-1385, 2007. Surgery has a good prognosis, although rupture can occur during surgical manipulation.

The most commonly accepted probable cause of ganglion cysts is the "herniation hypothesis", by which they are thought to occur as "an out-pouching or distention of a weakened portion of a joint capsule or tendon sheath." This description is based on the observations that the cysts occur close to tendons and joints. The microscopic anatomy of the cyst resembles that of tenosynovial tissue, the fluid being similar in composition to synovial fluid. Dye injected into the joint capsule frequently ends up in the cyst, which may become enlarged after activity.

Signs and symptoms include early satiety, nausea, vomiting, extreme "stabbing" postprandial abdominal pain (due to both the duodenal compression and the compensatory reversed peristalsis), abdominal distention/distortion, burping, external hypersensitivity or tenderness of the abdominal area, reflux, and heartburn. In infants, feeding difficulties and poor weight gain are also frequent symptoms. In some cases of SMA syndrome, severe malnutrition accompanying spontaneous wasting may occur.Free full text with registration at Medscape This, in turn, increases the duodenal compression, which worsens the underlying cause, creating a cycle of worsening symptoms.

Pain associated with osteoarthritis is secondary to joint capsule pain, due to joint distention and reduced range of motion, or to pain from the underlying bone, which may become damaged following erosion of the articular cartilage. Inflammatory products, such as inflammatory mediators and cytokines, damage articular cartilage and have been shown to weaken intra-articular ligaments. Therefore, treatment of joint disease should not only address the primary injury producing inflammation, but also the inflammatory cycle that leads to further tissue damage. Cryotherapy, joint lavage, systemic anti- inflammatories, or intra-articular medications are used to reduce joint inflammation.

Dry mucous membranes, decreased skin turgor, low jugular venous distention, tachycardia, and hypotension can be seen along with decreased urinary output. Patients in shock can appear cold, clammy, and cyanotic. Early signs and symptoms comprise tachycardia given rise to by catecholamine release, skin pallor due to vasoconstriction triggered by catecholamine release, hypotension followed by hypovolaemia and perhaps come after myocardial insufficiency, confusion, aggression, drowsiness and coma either caused by cerebral hypoxia or acidosis. Tachypnoea owing to hypoxia and acidosis, general weakness caused by hypoxia and acidosis, thirst induced by hypovolaemia and oliguria caused by reduced perfusion.

Symptoms are set into 3 categories: mild, moderate, and severe. Mild symptoms include abdominal bloating and feeling of fullness, nausea, diarrhea, and slight weight gain. Moderate symptoms include excessive weight gain (weight gain of greater than 2 pounds per day), increased abdominal girth, vomiting, diarrhea, darker urine, decreased urine output, excessive thirst, and skin and/or hair feeling dry (in addition to mild symptoms). Severe symptoms are fullness/bloating above the waist, shortness of breath, pleural effusion, urination significantly darker or has ceased, calf and chest pains, marked abdominal bloating or distention, and lower abdominal pains (in addition to mild and moderate symptoms).

|
Gas colic, also known as tympanic colic, is the result of gas buildup within the horse's digestive tract due to excessive fermentation within the intestines or a decreased ability to move gas through it. It is usually the result of a change in diet, but can also occur due to low dietary roughage levels, parasites (22% of spasmodic colics are associated with tapeworms), and anthelminthic administration. This gas buildup causes distention and increases pressure in the intestines, causing pain. Additionally, it usually causes an increase in peristaltic waves, which can lead to painful spasms of the intestine, producing subsequent spasmodic colic.

|
The sand can cause colic signs similar to other impactions of the large colon, and often causes abdominal distention As the sand or dirt irritates the lining of the bowel it can cause diarrhea. The weight and abrasion of the sand or dirt causes the bowel wall to become inflamed and can cause a reduction in colonic motility and, in severe cases, leads to peritonitis. Diagnosis is usually made by history, environmental conditions, auscultation of the ventral abdomen, radiographs, ultrasound, or fecal examination (See Diagnosis). Historically, medical treatment of the problem is with laxatives such as liquid paraffin or oil and psyllium husk.

Diaphragmatic hernias are rare in horses, accounting for 0.3% of colics. Usually the small intestine herniates through a rent in the diaphragm, although any part of the bowel may be involved. Hernias are most commonly acquired, not congenital, with 48% of horses having a history of recent trauma, usually through during parturition, distention of the abdomen, a fall, or strenuous exercise, or direct trauma to the chest. Congenital hernias occur most commonly in the most ventral part of the diaphragm, while acquired hernias are usually seen at the junction of the muscular and tendinous sections of the diaphragm.

Horses with small intestinal obstruction will usually have an intestinal diameter of -10 cm with a wall thickness of 3-5mm. Horses with proximal enteritis usually have an intestinal diameter that is narrower, but wall thickness is often greater than 6mm, containing a hyperechoic or anechoic fluid, with normal, increased, or decreased peristalsis. However, obstructions that have been present for some time may present with thickened walls and distention of the intestine. Horses experiencing intussusception may have a characteristic "bullseye" appearance of intestine on ultrasound, which is thickened, and distended intestine proximal to the affected area.

In cardiovascular physiology, end-diastolic volume (EDV) is the volume of blood in the right and/or left ventricle at end load or filling in (diastole) or the amount of blood in the ventricles just before systole. Because greater EDVs cause greater distention of the ventricle, EDV is often used synonymously with preload, which refers to the length of the sarcomeres in cardiac muscle prior to contraction (systole). An increase in EDV increases the preload on the heart and, through the Frank-Starling mechanism of the heart, increases the amount of blood ejected from the ventricle during systole (stroke volume).

The mare's reproductive system is responsible for controlling gestation, birth, and lactation, as well as her estrous cycle and mating behavior. It lies ventral to the 4th or 5th lumbar vertebrae, although its position within the mare can vary depending on the movement of the intestines and distention of the bladder. The mare has two ovaries, usually in length and thick, that generally tend to decrease in size as the mare ages. In equine ovaries, unlike in humans, the vascular tissue is cortical to follicular tissue, so ovulation can only occur at an ovulation fossa near the infundibulum.

It is important to differentiate DPI from small intestinal obstruction, since obstruction may require surgical intervention, but this can at times be difficult. Horses suffering from DPI usually have a higher protein concentration in their peritoneal fluid compared to horses with small intestinal obstruction, often without a concurrent increase in nucleated cell count. They usually have some relief and decrease in pain after gastric decompression, while horses with an obstruction often still act colicky after nasogastric intubation. Distention of the small intestine may be less than what is felt on rectal examination of horses with obstruction, especially after gastric decompression.

The weight of the liver was also part of diagnosis with a significantly greater weight than what is in normal limits (1,440-1,680g) indicative of vein distention. In a clinical setting, Bernheim claims that the presence of isolated right ventricular failure clearly came first with the presence of left ventricular hypertrophy coming secondary indicates the presence of his syndrome. This is especially considered when the heart failure is not due to a weakness in the myocardium but instead stenosis of the myocardial wall. Fluoroscopy to view the blood flow in the heart has also been deemed a reliable tool.

The patient is asked to lie down at 30 degrees with his/her head tilted 45 degrees to the left. Then an oblique light is used to illuminate the jugular region of the neck to help in identifying the inner jugular vein. Care must be taken not to confuse it with the external jugular, whose beating is more easily seen under the skin due to it being more superficial. In patients with severe right heart congestion, observation of the inner jugular might not be feasible due to its distention all the way into the upper neck and skull.

Rumination syndrome is a poorly understood disorder, and a number of theories have speculated the mechanisms that cause the regurgitation, which is a unique symptom to this disorder. While no theory has gained a consensus, some are more notable and widely published than others. The most widely documented mechanism is that the ingestion of food causes gastric distention, which is followed by abdominal compression and the simultaneous relaxation of the lower esophageal sphincter (LES). This creates a common cavity between the stomach and the oropharynx that allows the partially digested material to return to the mouth.

It is considerably shorter in the living body because the intestines, which are tubes of smooth muscle tissue, maintain constant muscle tone in a halfway-tense state but can relax in spots to allow for local distention and peristalsis. The gastrointestinal tract contains trillions of microbes, with some 4,000 different strains of bacteria having diverse roles in maintenance of immune health and metabolism. Cells of the GI tract release hormones to help regulate the digestive process. These digestive hormones, including gastrin, secretin, cholecystokinin, and ghrelin, are mediated through either intracrine or autocrine mechanisms, indicating that the cells releasing these hormones are conserved structures throughout evolution.

Volvulus of the large colon usually occurs where the mesentery attaches to the body wall, but may also occur at the diaphragmatic or sternal flexures, with rotations up to 720 degrees reported. It is most commonly seen in postpartum mares, usually presents with severe signs of colic that are refractory to analgesic administration, and horses often lie in dorsal recumbency. Abdominal distention is common due to strangulation and rapid engorgement of the intestine with gas, which then can lead to dyspnea as the growing bowel pushes against the diaphragm and prevents normal ventilation. Additionally, compression can place pressure on the caudal vena cava, leading to pooling of blood and hypovolemia.
|
|
Fluids are commonly given, either orally by nasogastric tube or by intravenous catheter, to restore proper hydration and electrolyte balance. In cases of strangulating obstruction or enteritis, the intestine will have decreased absorption and increased secretion of fluid into the intestinal lumen, making oral fluids ineffective and possibly dangerous if they cause gastric distention and rupture. This process of secretion into the intestinal lumen leads to dehydration, and these horse require large amounts of IV fluids to prevent hypotension and subsequent cardiovascular collapse. Fluid rates are calculated by adding the fluid lost during each collection of gastric reflux to the daily maintenance requirement of the horse.

|
Adhesions, or scar tissue between various organs that are not normally attached within the abdomen, may occur whenever an abdominal surgery is performed. It is often seen secondary to reperfusion injury where there is ischemic bowel or after intestinal distention. This injury causes neutrophils to move into the serosa and mesothelium to be lost, which the body then attempts to repair using fibrin and collagen, leading to adhesion formation between adjacent tissues with either fibrinous or fibrous material. Adhesions may encourage a volvulus, as the attachment provides a pivot point, or force a tight turn between two adjacent loops that are now attached, leading to partial obstruction.

Contracaecum larvae can infect humans, the human disease caused by infection of Anisakid nematodes such as Contracaecum is called anisakiasis (or anisakidosis) which is a painful and severe condition with infection usually being caused by the consumption of raw or undercooked fish which are host to the third stage larvae. The symptoms of anisakiasis include abdominal pain and distention, diarrhea and nausea, faeces with high proportions of blood and mucus and a mild fever. There can also be allergic reactions such as rash and itching, and occasionally there can also be anaphylaxis. Patients may require the removal of the parasite by endoscopy or surgery to treat this condition.

The fetus, which develops within a fluid-filled amniotic sac, relies on the placenta for respiratory gas exchange rather than the lungs. While not involved in fetal oxygenation, fetal breathing movements (FBM) nevertheless have an important role in lung growth and in development of respiratory muscles and neural regulation. FBM are regulated differently in many respects than postnatal respiration, which results from the unique intrauterine environment. At birth, the transition to continuous postnatal respiration involves a fall in temperature, gaseous distention of the lungs, activation of the Hering-Breuer reflex, and functional connectivity of afferent O2 chemoreceptor activity with respiratory motoneurons and arousal centers.

The rectoanal inhibitory reflex (RAIR) (also known as the anal sampling mechanism, anal sampling reflex, rectosphincteric reflex, or anorectal sampling reflex) is a reflex characterized by a transient involuntary relaxation of the internal anal sphincter in response to distention of the rectum. The RAIR provides the upper anal canal with the ability to discriminate between flatus and fecal material. The ability of the rectum to discriminate between gaseous, liquid and solid contents is essential to the ability to voluntarily control defecation. The RAIR allows for voluntary flatulation to occur without also eliminating solid waste, irrespective of the presence of fecal material in the anal canal.

Niemann–Pick cell in spleen Niemann–Pick diseases are a subgroup of lipid storage disorders called sphingolipidoses in which harmful quantities of fatty substances, or lipids, accumulate in the spleen, liver, lungs, bone marrow, and brain. In the classic infantile type-A variant, a missense mutation causes complete deficiency of sphingomyelinase. Sphingomyelin is a component of cell membrane including the organellar membrane, so the enzyme deficiency blocks degradation of lipid, resulting in the accumulation of sphingomyelin within lysosomes in the macrophage-monocyte phagocyte lineage. Affected cells become enlarged, sometimes up to 90 μm in diameter, secondary to the distention of lysosomes with sphingomyelin and cholesterol.

In the management of small bowel obstructions, a commonly quoted surgical aphorism is: "never let the sun rise or set on small-bowel obstruction" because about 5.5% of small bowel obstructions are ultimately fatal if treatment is delayed. Improvements in radiological imaging of small bowel obstructions allow for confident distinction between simple obstructions, that can be treated conservatively, and obstructions that are surgical emergencies (volvulus, closed-loop obstructions, ischemic bowel, incarcerated hernias, etc.). A small flexible tube (nasogastric tube) may be inserted through the nose into the stomach to help decompress the dilated bowel. This tube is uncomfortable but relieves the abdominal cramps, distention, and vomiting.

It is used to manage chronic loose or frequent stools in any condition or disease where diarrhea is chronically present, such as in patients with diarrhea-predominant irritable bowel syndrome (IBS-D), inflammatory bowel disease (IBD), small intestinal bacterial overgrowth (SIBO), recurrent Clostridium difficile-infection associated diarrhea, microscopic colitis or HIV-related enteropathy as well as many other diseases and conditions resulting in chronic diarrhea. EnteraGam is manufactured by Entera Health and distributed by RedHill Biopharma. The overall AE rate (Adverse Events rate) is less than 0.4%. The most common AEs reported by patients administered EnteraGam include mild constipation (23), headache (13), mild diarrhea (11), nausea (8), abdominal pain (8), abdominal distention (7) and hives (7).

Small intestinal volvulus is thought to be caused by a change in local peristalsis, or due to a lesion that the mesentery may twist around (such as an ascarid impaction), and usually involves the distal jejunum and ileum.w It is one of the most common causes of small intestinal obstruction in foals, possibly because of a sudden change to a bulkier foodstuff. Animals present with acute and severe signs of colic, and multiple distended loops of small intestine, usually seen radiographically in a foal. Small intestinal volvulus often occurs secondary to another disease process in adult horses, where small intestinal obstruction causes distention and then rotation around the root of the mesentery.

It first appeared in the medical literature in Omissions from the Materia Medica, by Chen Cangqi, in 720 AD. Bitter in taste, aromatic, and neutral in temperature, lu lu tong is claimed to promote the movement of blood and qi, water metabolism and urination, expels wind, and unblocks the channels. It is an ingredient in formulas for epigastric distention or abdominal pain, anemia, irregular or scanty menstruation, low back or knee pain and stiffness, edema with difficult urination, or nasal congestion. In the fall, the trees drop their hard, spiky seedpods by the hundreds, which can become a serious nuisance on pavements and lawns. Some US cities have expedited permits to remove liquidambar trees.

This technique was only executed by M1 and M5. These new techniques are thought to have been developed by these whales to help them herd small schooling fish (likely capelin) in the well-mixed waters of the Saguenay Fjord; these tactics were not observed in the nearby Laurentian Channel Head, where "strong tidal currents, a stratified water column and bottom topography combine to create large areas of upwelling in which prey are forced to the surface". In July 2007, a minke whale with what appeared to be a rope injury was observed surface feeding on capelin in the Gulf of St. Lawrence. The long, linear laceration extended around the ventral pleats, restricting their distention.

Early signs of abnormality include polyhydramnios (an excess of amniotic fluid), low birth weight, and feeding intolerance immediately after birth, in particular a tendency to epigastric distention associated with non-biliary vomiting (the obstruction is generally above the papilla of Vater, therefore superior than the junction with the bile ducts). Different chromosomal diseases (for example trisomy 21 and, with a minor frequency, trisomy 18 and trisomy 13) are present in about 33% of subjects affected by annular pancreas. In adults, the clinical picture is often dominated by the sensation of postprandial distension, abdominal pain in the epigastric region, nausea and vomiting that may be present for a long time (sometimes for years) before reaching a precise diagnosis.

Inflammation of the intestine leads to the secretion of a large amounts of electrolytes, primarily sodium and chloride, into its lumen, resulting in the osmotic movement of water. The production of fluid is thought to be due to active hypersecretion, passive secretion of proteins secondary to damage to epithelium of the mucosa and capillaries, and a functional ileus which prevents removal of this fluid. Massive fluid production results in extensive reflux, usually produced at a rate of 50–100 mL/min, in addition to distention of the proximal small intestine, dehydration, and possible shock secondary to hypovolemia. Proximal enteritis can also occur with inflammation of other organs in the gastrointestinal tract, including gastritis, ileitis, typhlitis, and colitis.

As megalocytiviruses have only been recently identified and described, the pathogenesis of megalocytivirus infection is relatively poorly understood. Clinical signs associated with infection are nonspecific and may include appetite loss, uncoordinated swimming, lethargy, coelomic distention, darkening skin color, petechiae, fin erosion, and death. Large conspicuous hypertrophied cells, for which the genus is named, are evident in multiple organs when diseased tissues are examined by histopathology; these distinctive cells are commonly observed in the kidney, spleen and gastrointestinal tract and less commonly seen in the liver, gills, heart, and connective tissue. The hypertrophied cells are frequently perivascular in distribution and are greatly enlarged due to large granular to foamy basophilic cytoplasmic inclusion bodies.

The distention continued in this match, as the tecnico team won both the first and the second fall straight out. Following the match Hooligan attacked Virus, including throwing Virus hard against the steel guardrail, ending the attack by tearing Virus' Los Cancerberos del Infierno tights apart. In the third fall high flying tecnicosÁngel de Oro, El Hijo del Fantasma and Rey Cometa took on the rudo (Bad guy) team of La Fievre Amarilla ("The Yellow Fever") team of Japanese wrestlersOkumura and Namajague, teaming up with Mexican Misterioso, Jr. Ángel de Oro won the first fall for his team when he forced Okumura to submit after applying a La Mecedora (Modified Campana) hold. The rudo team came back and won the second fall, pushing the match to its full three falls.

Coeliac disease with "classic symptoms", which include gastrointestinal manifestations such as chronic diarrhoea and abdominal distention, malabsorption, loss of appetite, and impaired growth, is currently the least common presentation form of the disease and affects predominantly to small children generally younger than two years of age. Coeliac disease with "non-classic symptoms" is the most common clinical type and occurs in older children (over 2 years old), adolescents and adults. It is characterized by milder or even absent gastrointestinal symptoms and a wide spectrum of non-intestinal manifestations that can involve any organ of the body, and very frequently may be completely asymptomatic both in children (at least in 43% of the cases) and adults. Following a lifelong gluten-free diet is the only medically-accepted treatment for people with coeliac disease.

A food poisoning outbreak of 26 cases in the Ganyudo area of Suruga Bay, Shizuoka Prefecture in Japan in September 1965 was traced to ingestion of the toxin surugatoxin (SGTX), named for Suruga Bay. SGTX is contained in the mid-gut digestive gland of the Japanese ivory mollusk, Babylonia japonica, which is used as an ingredient in sushi and sashimi. The food-poisoning patients reported a variety of symptoms, including visual disorders, speech disorders, lazy eye amblyopia, pupil dilation (mydriasis), abdominal distention, dry mouth, numbness of lips, constipation, and vomiting. The toxicity shellfish from the Suruga Bay area varied with time – the toxicity was only present during July through September, when temperatures sometimes reached 25°C and it rapidly declined after 1978, making the availability of surugatoxin and the related substances neosurugatoxin and prosurugatoxin unavailable for research.

CD is associated with some other autoimmune diseases, such as diabetes mellitus type 1, thyroiditis, gluten ataxia, psoriasis, vitiligo, autoimmune hepatitis, dermatitis herpetiformis, primary sclerosing cholangitis, and more. CD with "classic symptoms", which include gastrointestinal manifestations such as chronic diarrhea and abdominal distention, malabsorption, loss of appetite, and impaired growth, is currently the least common presentation form of the disease and affects predominantly small children generally younger than two years of age. CD with "non-classic symptoms" is the most common clinical type and occurs in older children (over 2 years old), adolescents, and adults.

Enteroliths are not a common cause of colic, but are known to have a higher prevalence in states with a sandy soil or an abundance of alfalfa hay is fed, such as California, a state where 28% of surgical colics are due to enteroliths. Alfalfa hay is thought to increase the risk due to the high protein content in the hay, which would likely elevate ammonia nitrogen levels within the intestine. They may be more common in horses with diets high in magnesium, and are also seen more often in Arabians, Morgans, American Saddlebreds, miniature horses, and donkeys, and usually occur in horses older than four years of age. Horses with enteroliths typically have chronic, low-grade, recurring colic signs, which may lead to acute colic and distention of the large colon after occlusion of the lumen occurs.

Cathartic preparation should be performed in order to clean residual stool from bowel loops from to allow a better visualization of mucosal features and an easier luminal distention as well. This type of preparation usually implies a fiber restricted diet and intake of water solution with laxative effect few days before the exam, and abstaining from food intake starting from six hours prior to the study. Use of enteric contrast media is recommended, aiming to distend small bowel loops, and it is administered orally at regular intervals approximately 40 minutes before the study. The type of endo-luminal contrast media varies among negative contrast media, consisting of superparamagnetic agents that evoke low signal both in T1 and T2 weighted images, positive contrast media, represented by paramagnetic agents, that produce high signal on both sequences, or biphasic contrast media, that gives high signal intensity in T2 and low intensity in T1.

The Greek physician Galen may have been the first to describe artificial ventilation: "If you take a dead animal and blow air through its larynx through a reed, you will fill its bronchi and watch its lungs attain the greatest distention." Vesalius too describes ventilation by inserting a reed or cane into the trachea of animals. In 1773, English physician William Hawes (1736–1808) began publicizing the power of artificial ventilation to resuscitate people who superficially appeared to have drowned. For a year he paid a reward out of his own pocket to any one bringing him a body rescued from the water within a reasonable time of immersion. Thomas Cogan, another English physician, who had become interested in the same subject during a stay at Amsterdam, where was instituted in 1767 a society for preservation of life from accidents in water, joined Hawes in his crusade. In the summer of 1774 Hawes and Cogan each brought fifteen friends to a meeting at the Chapter Coffee-house, St Paul's Churchyard, where they founded the Royal Humane Society as a campaigning group for first aid and resuscitation.

Pericarditis can progress to pericardial effusion and eventually cardiac tamponade. This can be seen in people who are experiencing the classic signs of pericarditis but then show signs of relief, and progress to show signs of cardiac tamponade which include decreased alertness and lethargy, pulsus paradoxus (decrease of at least 10 mmHg of the systolic blood pressure upon inspiration), low blood pressure (due to decreased cardiac index), (jugular vein distention from right sided heart failure and fluid overload), distant heart sounds on auscultation, and equilibration of all the diastolic blood pressures on cardiac catheterization due to the constriction of the pericardium by the fluid. In such cases of cardiac tamponade, EKG or Holter monitor will then depict electrical alternans indicating wobbling of the heart in the fluid filled pericardium, and the capillary refill might decrease, as well as severe vascular collapse and altered mental status due to hypoperfusion of body organs by a heart that can not pump out blood effectively. The diagnosis of tamponade can be confirmed with trans-thoracic echocardiography (TTE), which should show a large pericardial effusion and diastolic collapse of the right ventricle and right atrium.
