Chronic hepatitis is a long-term inflammation of the liver caused by a viral infection. It can lead to scarring of the liver, known as cirrhosis, and even liver cancer. Common causes of chronic hepatitis include hepatitis B and C viruses, but other viruses, toxins, and autoimmune diseases can also cause chronic hepatitis. Treatment for chronic hepatitis depends on the cause and may include antiviral medications, lifestyle changes, and in some cases, surgery.
