The bile acid sequestrants are a group of resins used to bind certain components of bile in the gastrointestinal tract. They disrupt the enterohepatic circulation of bile acids by combining with bile constituents and preventing their reabsorption from the gut.
It has also been called bile acid-induced diarrhea, cholerheic or choleretic enteropathy, bile salt diarrhea or bile salt malabsorption. It can result from malabsorption secondary to gastrointestinal disease, or be a primary disorder, associated with excessive bile acid production. Treatment with bile acid sequestrants is often effective ...
Biliary reflux can be confused with acid reflux, also known as gastroesophageal reflux disease (GERD). While bile reflux involves fluid from the small intestine flowing into the stomach and esophagus, acid reflux is the backflow of stomach acid into the esophagus. These conditions are often related, and differentiating between the two can be ...
Plus, high-fat foods cause the body to release bile salts and a hormone called cholecystokinin, which relaxes the lower esophageal sphincter, or LES, letting more acid wash up into the esophagus ...
Colestyramine or cholestyramine (trade names Questran, Questran Light, Cholybar, Olestyr) is a bile acid sequestrant, which binds bile in the gastrointestinal tract to prevent its reabsorption. It is a strong ion exchange resin , which means it can exchange its chloride anions with anionic bile acids in the gastrointestinal tract and bind them ...
Ursodeoxycholic acid (UDCA), also known as ursodiol, is a secondary bile acid, produced in humans and most other species from metabolism by intestinal bacteria. It is synthesized in the liver in some species, and was first identified in bile of bears of genus Ursus , from which its name derived. [ 8 ]
Dr. Vincent M. Pedre III, MD, FMCP, says acid reflux, also known as gastroesophageal reflux disease (GERD), is a condition that affects up to 20 percent of the American population. Some sources ...
As bile acids are made from endogenous cholesterol, disruption of the enterohepatic circulation of bile acids will lower cholesterol. Bile acid sequestrants bind bile acids in the gut, preventing reabsorption. In so doing, more endogenous cholesterol is shunted into the production of bile acids, thereby lowering cholesterol levels.
