Primary bile acid diarrhea (Type 2 bile acid "malabsorption") may be caused by an overproduction of bile acids. [5] [9] Several groups of workers have failed to show any defect in ileal bile acid absorption in these patients, and they have an enlarged bile acid pool, rather than the reduced pool expected with malabsorption. [10]
Dietary modification is important in some conditions: Gluten-free diet in coeliac disease. Lactose avoidance in lactose intolerance. Antibiotic therapy to treat Small Bowel Bacterial overgrowth. Cholestyramine or other bile acid sequestrants will help with reducing diarrhoea in bile acid malabsorption.
Primary bile acid malabsorption, a gut defect in the reabsorption of bile acids in the small intestine which results in increased levels of bile acids in the colon leading to watery diarrhea and bloating. [31] Chronic infection of C. difficile, G. lamblia. C. difficile — bacteria that can be the source of diarrhea. [32]
Bypassing the major site of bile acid reabsorption in the small intestine therefore further reduces fat and fat-soluble vitamin absorption. As a result, huge amounts of fatty acids , which are normally absorbed in the small intestine, enter the colon, where they cause irritation of the colon wall and the secretion of excessive volumes of water ...
Bile salt diarrhea can also be a side-effect of gallbladder removal. [1] Bile acid sequestrants are the principal therapy for bile acid-induced diarrhea. [7] [1] Cholestyramine, colestipol and colesevelam have all been used. Doses may not need to be as high as those previously used for hyperlipidemia.
Typically, the patient is recommended a dietary restriction table with fatty foods, enzyme preparations, antispasmodics, and sometimes cholagogue. [citation needed] If the pain is caused by biliary microlithiasis, oral ursodeoxycholic acid can alleviate the condition. [5] A trial of bile acid sequestrant therapy is recommended for bile acid ...
Cholic acid, 3α,7α,12α-trihydroxy-5β-cholan-24-oic acid, the most abundant bile acid in humans and many other species, was discovered before chenodeoxycholic acid. It is a tri-hydroxy-bile acid with 3 hydroxyl groups (3α, 7α and 12α). In its synthesis in the liver, 12α hydroxylation is performed by the additional action of CYP8B1. As ...
Persons with short bowel syndrome may have complications caused by malabsorption of vitamins and minerals, such as deficiencies in vitamins A, D, E, K, B 9 (folic acid), and B 12, calcium, magnesium, iron, and zinc. These may appear as anemia, hyperkeratosis (scaling of the skin), easy bruising, muscle spasms, poor blood clotting, and bone pain.
