Primary Biliary Cholangitis: Causes, Symptoms, and Treatment

Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 23, 2026.

What kind of doctor treats Primary Biliary Cholangitis?

A hepatologist, a doctor who treats liver disease, usually treats primary biliary cholangitis. A gastroenterologist, a doctor who treats digestive problems, may also help. It is a long-term disease in which the small bile ducts in the liver become inflamed and are slowly destroyed. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.

What is primary biliary cholangitis?

Bile ducts are tubes that move bile from the liver to the small intestine. Bile is a substance that helps with digestion. In primary biliary cholangitis, the small bile ducts in the liver become inflamed and are eventually destroyed. When there are no bile ducts, bile builds up and causes liver damage. Over time, this damage can lead to liver scarring, cirrhosis, and eventually liver failure. In cirrhosis, scar tissue replaces healthy liver tissue and keeps the liver from working normally.

It is believed to be an autoimmune disease. This means the body's own immune system attacks healthy bile duct cells. The disease used to be called primary biliary cirrhosis, and doctors often use the short name PBC.

Symptoms

Many people have no symptoms when they are first diagnosed. The most common symptoms are feeling tired and having itchy skin. Other symptoms may include:

  • Discomfort or pain in the upper-right side of the belly.
  • Joint pain or arthritis.
  • Dry eyes and dry mouth.

As the disease gets worse, the skin may darken and yellow bumps called xanthomas may appear. Later signs can include swelling in the legs and belly, jaundice (yellow skin and eyes), and weight loss. Stools may turn pale.

Causes and who gets it

Experts are not sure what causes PBC. Certain genes make some people more likely to develop it. In those people, things in the environment may trigger the immune system to attack the small bile ducts. Possible triggers include infections, cigarette smoking, and exposure to certain chemicals.

PBC is more common in women than in men and in people who are middle aged. It is also more common in people who have a parent or sibling with PBC. Common complications include high cholesterol and weak bones, called osteoporosis. Levels of vitamins A, D, E, and K can also run low. People with cirrhosis from PBC, and men with PBC, have a higher risk of liver cancer.

How doctors diagnose it

Doctors diagnose PBC from your medical and family history, a physical exam, and medical tests. A blood test can look for anti-mitochondrial antibodies (AMA), which are found in the blood of about 95% of people with PBC. A liver test may show a high level of alkaline phosphatase. This is a liver enzyme that rises when bile ducts are destroyed or blocked. A doctor may diagnose PBC with AMA and a high alkaline phosphatase level, even with no other signs. In a liver biopsy, a doctor takes small pieces of liver tissue to look at under a microscope.

Treatment

Doctors treat PBC with medicines. A doctor may prescribe ursodiol, which does not cure PBC but can slow liver damage. People who respond to ursodiol early can live longer without needing a liver transplant. Other FDA-approved medicines include seladelpar and elafibranor. A medicine called cholestyramine may reduce itching.

Doctors can also treat problems caused by PBC. For weak bones, a doctor may prescribe medicines that slow or stop bone loss. For low vitamin levels, a doctor may suggest vitamin A, D, E, and K supplements. Follow your doctor's instructions on the type and amount of vitamins you take. A doctor considers a liver transplant when PBC leads to liver failure.

To help protect your liver, quit smoking, avoid alcohol, and go to regular checkups. If you have cirrhosis, stop drinking alcohol completely.

When to see a doctor

Contact your provider if you have belly swelling, jaundice, or itching that does not go away. Call 911 or go to the emergency room if you vomit blood, have bloody or black stools, faint, have severe belly pain, or have sudden new confusion.

How a direct primary care or concierge doctor fits in

A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. They can arrange the first blood tests, help watch for problems like weak bones, and coordinate care with a liver specialist.

Common questions

Is primary biliary cholangitis the same as primary biliary cirrhosis?

Yes, it is the same disease with a newer name.

Does ursodiol cure primary biliary cholangitis?

No, ursodiol does not cure PBC, but it can slow liver damage. Other FDA-approved medicines are also available. A liver transplant is considered if the liver fails.

Does primary biliary cholangitis always cause symptoms?

No, many people have no symptoms when they are first diagnosed. Doctors diagnose about 60% of people with PBC before symptoms begin, and blood tests find it.

Can I do anything to protect my liver?

Yes, you can take steps to help prevent further liver damage. These steps include taking your medicines as directed, quitting smoking, avoiding alcohol, and going to regular checkups.
