Bile acid malabsorption (BAM), known also as bile acid diarrhea, is a cause of several gut-related problems, the main one being chronic diarrhea.It has also been called bile acid-induced diarrhea, cholerheic or choleretic enteropathy, bile salt diarrhea or bile salt malabsorption.
These conjugated bile acids are often referred to as bile salts. The pKa of the unconjugated bile acids are between 5 and 6.5, [ 4 ] and the pH of the duodenum ranges between 3 and 5, so when unconjugated bile acids are in the duodenum, they are almost always protonated (HA form), which makes them relatively insoluble in water.
Bile is secreted by the liver into small ducts that join to form the common hepatic duct. [4] Between meals, secreted bile is stored in the gallbladder. [5] During a meal, the bile is secreted into the duodenum (part of the small intestine) to rid the body of waste stored in the bile as well as aid in the absorption of dietary fats and oils. [5]
In the human liver, bile is composed of 97–98% water, 0.7% bile salts, 0.2% bilirubin, 0.51% fats (cholesterol, fatty acids, and lecithin), and 200 meq/L inorganic salts. [ 2 ] [ 3 ] The two main pigments of bile are bilirubin , which is orange-yellow, and its oxidised form biliverdin , which is green.
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.
Calculi of the gallbladder and bile ducts are called gallstones and are primarily developed from bile salts and cholesterol derivatives. Calculi in the nasal passages are rare. Calculi in the gastrointestinal tract (enteroliths) can be enormous. Individual enteroliths weighing many pounds have been reported in horses.
But some research has noted rare but serious side effects of once-weekly, 2.4-milligram (mg) semaglutide injections, such as pancreatitis, acute kidney injury, gallbladder issues, and thyroid cancer.
The bile components that form gallstones include cholesterol, bile salts, and bilirubin. [2] Gallstones formed mainly from cholesterol are termed cholesterol stones, and those formed mainly from bilirubin are termed pigment stones. [2] [3] Gallstones may be suspected based on symptoms. [4] Diagnosis is then typically confirmed by ultrasound. [2]
