Disaccharidases are glycoside hydrolases, enzymes that break down certain types of sugars called disaccharides into simpler sugars called monosaccharides.In the human body, disaccharidases are made mostly in an area of the small intestine's wall called the brush border, making them members of the group of "brush border enzymes".
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 ...
D-xylose absorption test is a medical test performed to diagnose conditions that present with malabsorption of the proximal small intestine [1] due to defects in the integrity of the gastrointestinal mucosa. [2] D-xylose is a monosaccharide, or simple sugar, that does not require enzymes for digestion prior to absorption. Its absorption ...
Recent study indicates "The role of testing for SIBO in individuals with suspected IBS remains unclear." [14] The excess hydrogen or methane is assumed to be typically caused by an overgrowth of otherwise normal intestinal bacteria. [11] [1] [4] [12] [13] [8] Other breath tests that can be taken include: sucrose intolerance, d-xylose and sorbitol.
Glucose-galactose malabsorption is a rare disorder; only a few hundred cases have been identified worldwide. However, as many as 10 percent of the population may have a somewhat reduced capacity for glucose absorption without associated health problems. This condition may be a milder variation of glucose-galactose malabsorption. [2]
Although first described in 1994, [1] [2] [3] it was first documented in the U.S. by Scott Commins and Thomas Platts-Mills during their research on alpha-gal allergy. [4] It is called "pork–cat syndrome" because it is a cross-reactivity where an allergy to cat serum albumin (protein made by a cat's liver) [4] cross-reacts with pork albumin ...
Compared to static tests that nearly everyone has experienced, with a fixed set of items administered to all examinees, computer-adaptive tests require fewer test items to arrive at equally accurate scores. [2] The basic computer-adaptive testing method is an iterative algorithm with the following steps: [3]
The cat is monitored frequently during the first few months of treatment; The cat eats a diet low in carbohydrates and high in protein. Cats may present with type 2 (insulin-resistant) diabetes, at least at first, but hyperglycemia and amyloidosis, left untreated, will damage the pancreas over time and progress to insulin-dependent diabetes.
