Overview

Autoimmune hepatitis is liver inflammation that occurs when your body's immune system turns against liver cells. The exact cause of autoimmune hepatitis is unclear, but genetic and enviromental factors appear to interact over time in triggering the disease.

Untreated autoimmune hepatitis can lead to scarring of the liver (cirrhosis) and eventually to liver failure. When diagnosed and treated early, however, autoimmune hepatitis often can be controlled with drugs that suppress the immune system.

A liver transplant may be an option when autoimmune hepatitis doesn't respond to drug treatments or in cases of advanced liver disease.
