What is primary biliary cholangitis?
Primary biliary cholangitis is the new name for primary biliary cirrhosis, or PBC. Primary biliary cholangitis is a chronic disease in which the small bile ducts in the liver become injured and inflamed and are eventually destroyed. When there are no bile ducts, bile builds up and causes liver damage. This damage can lead to liver scarring, cirrhosis, and eventually liver failure. Primary biliary cholangitis is believed to be an autoimmune disease, which means that the immune system is overactive and attacks normal, healthy bile duct cells.
How common is primary biliary cholangitis?
Researchers estimate that in the United States, about 65 out of every 100,000 women and about 12 out of every 100,000 men have primary biliary cholangitis.1
