Risk factorsBy Mayo Clinic staff
The following factors may increase your risk of primary biliary cirrhosis:
- Your sex. The great majority of people with primary biliary cirrhosis are women.
- Your age. Primary biliary cirrhosis is most likely to occur in people 30 to 60 years old.
- Infection. Researchers suspect primary biliary cirrhosis could be triggered by a bacterial, fungal or parasitic infection, which would explain the massing of white blood cells in the small bile ducts.
