Primary Biliary Cirrhosis
Condition
(PBC)
Definition
Primary biliary cirrhosis (PBC) is a liver disease that results in swelling of the bile ducts. Bile is a fluid made by the liver that helps break down food in the intestines. It is carried from the liver to the gallbladder and small intestine through bile ducts.
PBC makes it hard for bile to move out of the liver because it cannot pass through the ducts. This causes it to backup and leads to liver damage.
Causes
The exact cause of PBC is not known. It appears to be a problem with the immune system attacking health tissue. Genes and the environment may play a role.
Risk Factors
PBC is more common in women. Other things that may play a role are:
- A family history of PBC
- Viral hepatitis—both hepatitis B and C
Symptoms
Symptoms of PBC include:
- Tiredness
- Itchy skin
- Yellowing of the skin and eyes
- Yellow or white bumps around the eyelids
- Damaged blood vessels just below the surface of the skin
- Belly pain, especially in upper right side
Diagnosis
The doctor will ask about symptoms and past health. A physical exam will be done.
Blood tests will be done to check liver function.
A sample of the liver may be taken to look for damage. This can be done with a biopsy.
Pictures of the bile ducts may be taken. This can be done with:
- MRI scan
- CT scan
- Ultrasound
- Endoscopic retrograde cholangiopancreatography (ERCP)
