Primary biliary cirrhosis
Type of disease: Rare conditions
Primary biliary cirrhosis is a chronic disease that affects the bile ducts within the liver. The bile ducts become inflamed and damaged, which causes bile to build up in the liver. This abnormal buildup destroys liver tissue and results in cirrhosis. Primary biliary cirrhosis usually occurs between the ages of 40 and 60 and affects women more often than men. The cause of this condition is unknown, but research suggests that it is an autoimmune disease. Ursodiol is the only drug approved by the U.S. Food and Drug Administration for the treatment of primary biliary cirrhosis.
