| intestinal gas | The complaint referred to as intestinal gas is a common one and the discomfort can be quite significant. Everyone has gas and eliminates it by burping or passing it through the rectum. In many instances people think they have too much gas when in reality they have normal amounts. most people produce 1 to 3 pints of intestinal gas in 24 hours and pass gas an average of 14 times a day. It is made up primarily of odourless vapors such as carbon dioxide, oxygen, nitrogen, hydrogen, and in some families, methane. The unpleasant odour is due to bacteria in the large intestine that release small amounts of gases containing sulfur. (12 Dec 1998) |

| intestinal intoxication | A disorder resulting from absorption of the waste products of metabolism, decomposed matter from the intestine, or the products of dead and infected tissue as in gangrene. Synonym: autotoxicosis, endogenic toxicosis, enterotoxication, enterotoxism, intestinal intoxication, self-poisoning. (05 Mar 2000) |
| intestinal juice | An alkaline straw-coloured fluid secreted by the intestinal glands; its enzymes (peptidases, saccharases, nucleases, lecithinases, phosphatases, lipases) complete the hydrolysis of carbohydrates, proteins, and lipids. (05 Mar 2000) |
| intestinal lipodystrophy | <gastroenterology> A rare disorder of intestinal malabsorption that occurs as the result of the intestine. Treatment is with antibiotics. (27 Sep 1997) |
| intestinal lymphangiectasia | <radiology> Sxs: diarrhoea, hypoproteinaemia, oedema (peripheral or abdominal), protein-losing enteropathy, small bowel: thickened jejunal folds, spiculation, fuzzy borders, Differential diagnosis: other causes of low-protein states ( cirrhosis, nephrosis), aetiology: obstruction of lymphatics in intestinal wall, often associated with underdevelopment of thoracic duct, diagnosis usually made before 5yrs, but occasionally in teens, treatment: medium-chain triglycerides (MCT), prognosis: some recover, some stay on MCT diet, others relapse (12 Dec 1998) |
| intestinal lymphangiectasis | Familial lymphangiectasis with intestinal loss of lymph causing lymphocytopenia and hypogammaglobulinaemia. (05 Mar 2000) |
| intestinal malabsorption | <gastroenterology> The inadequate absorption of nutrients from the small intestine. This can result in loss of weight and abnormal appearing stools. Malabsorption can be caused by lesions of the small intestine, amyloidosis, lack of digestive enzymes (for example lactose intolerance) or bile salts or surgical operations. (10 Jan 1998) |
| intestinal metaplasia | The transformation of mucosa, particularly in the stomach, into glandular mucosa resembling that of the intestines, although usually lacking villi. (05 Mar 2000) |
| intestinal mucosa | The innermost membrane of the four coats of the intestinal wall, the other three being the submucosa, muscular layers, and serosa. (berk et al., gastroenterology, 4th ed, v.3, p1479) (12 Dec 1998) |
| intestinal myiasis | Presence of larvae of certain dipterous insects in the gastrointestinal tract, as of Musca domestica (domestic housefly), the cheese mite, and Fannia canicularis (lesser housefly). (05 Mar 2000) |
| intestinal obstruction | <surgery> A blockage of the bowel lumen prohibiting the passage of material. Common symptoms include constipation, abdominal swelling and abdominal pain. Treatment includes intravenous fluids, rest, nasogastric suction and surgery in select cases. (27 Sep 1997) |
| intestinal perforation | <surgery> This surgical emergency involves rupture of the wall of the intestine. Intestinal perforation results in severe abdominal pain intensified by movement. Later symptoms include fever and chills. Underlying causes include appendicitis, gastrointestinal cancer and diverticulitis. (10 Jan 1998) |
| intestinal polyps | Pedunculated or sessile growths arising from the intestinal mucosa and extending into the lumen. The disease includes intestinal polyposis. (12 Dec 1998) |
| intestinal pseudo-obstruction | <radiology> Chronic idiopathic intestinal pseudo-obstruction, autosomal dominant, variable penetrance, insidious onset in child or young adult, intermittent episodes, dysphagia, vomiting, abdominal pain/distention, diarrhoea, constipationn, small bowel involvement most common, megaduodenum, ileus simulating obstruction (12 Dec 1998) |
| intestinal rotation | See: malrotation. Molecular rotation, one hundredth of the product of the specific rotation of an optically active compound and its molecular weight. Optical rotation, the change in the plane of polarization of polarised light of a given wavelength upon passing through optically active substances; measured in terms of specific rotation by polarimetry, an important tool in chemical structural work, especially on carbohydrates. Specific optical rotation ([a]), the arc through which the plane of polarised light is rotated by 1 gram of a substance per milliliter of water when the length of the light path through the solution is 1 decimeter, typically using light corresponding to the D line of sodium.
