Description
Autoimmune hepatitis is a condition that occurs when your immune system mistakenly targets and attacks your liver cells, leading to long-term chronic liver inflammation, swelling, and damage. It may occur at any age and typically affects women more than men. It is often linked to other autoimmune diseases. The precise cause of autoimmune hepatitis is not fully understood, but it's believed that a combination of genetic and environmental factors plays a role in initiating the disease over time. When diagnosed and treated promptly, autoimmune hepatitis can often be managed with medications that dampen the immune response. In situations where drug treatments don't work or in advanced liver disease cases, a liver transplant might be considered an option.
