Hepatitis an inflammation of the liver may be caused by drugs, alcohol use, or certain medical conditions. But in most cases, it’s caused by a virus. This is known as viral hepatitis, and the most common forms are hepatitis A, B, and C.
Chronic hepatitis can quietly attack the liver for years without causing any symptoms. Unless the infection is diagnosed, monitored, and treated, many of these people will eventually have serious liver damage. Fortunately, blood tests can determine whether you have viral hepatitis, and if so, which kind.
