Introduction
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 bear bile, which is the derivation of its name Ursus. In purified form, it has been used to treat or prevent several diseases of the liver or bile ducts.
UDCA has been used as medical therapy in gallstone disease (cholelithiasis) and for biliary sludge. UDCA helps reduce the cholesterol saturation of bile and leads to gradual dissolution of cholesterol-rich gallstones.
UDCA may be given after bariatric surgery to prevent cholelithiasis, which commonly occurs due to the rapid weight loss producing biliary cholesterol oversaturation and also biliary dyskinesia secondary hormonal changes.
