Cirrhosis of the liver is scarring of the liver after a long period of liver inflammation. The most common causes of liver inflammation are alcohol and viral hepatitis B or C. Hepatitis B and C are infections usually spread by contact with infected blood (for instance, sharing needles while using street drugs) or through sexual contact. Only a small percentage of cases of hepatitis B go on to cirrhosis.

This program only uses alcohol as a risk factor in individualizing your risk of cirrhosis.

You can get more information about alcohol from the CDC website or from AA.
