Primary biliary cholangitis (often referred to as primary biliary cirrhosis) is an autoimmune disorder that causes inflammation and scarring of the bile ducts inside the liver, causing continual liver damage and blockage of the bile flow. It is found most frequently in women between the ages of 35 and 60. More than 90% of those affected by primary biliary cirrhosis will have high levels of antimitochondrial antibodies.
