Primary Biliary Cholangitis (Primary Biliary Cirrhosis)
View or Print All Sections
Definition & Facts
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.
Symptoms & Causes
Common early symptoms of primary biliary cholangitis are feeling tired and having itchy skin. Many people have no symptoms when they are first diagnosed. Experts aren’t sure what causes primary biliary cholangitis, but genes and environmental triggers may play a role.
Doctors diagnose primary biliary cholangitis based on your medical and family history, a physical exam, and the results of medical tests. Medical tests used to diagnose primary biliary cholangitis may include blood tests, imaging tests, and liver biopsy.
Doctors treat primary biliary cholangitis with medicines. Doctors may treat the symptoms and complications of the disease with medicines, dietary supplements, changes in diet and lifestyle, and medical procedures.
Eating, Diet, & Nutrition
A healthy, well-balanced diet is important in all stages of primary biliary cholangitis. Your doctor can recommend a healthy eating plan that provides enough calories and nutrients to help your liver work properly and manage complications.
The NIDDK conducts and supports clinical trials in many diseases and conditions, including liver diseases. The trials look to find new ways to prevent, detect, or treat disease and improve quality of life.

Your Digestive System & How It Works
The digestive system is made up of the gastrointestinal (GI) tract—also called the digestive tract—and the liver, pancreas, and the gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.
