Hepatitis Summary Your liver is the largest organ inside your body. It helps your body digest food, store energy, and remove poisons. Hepatitis is an inflammation of the liver. Viruses cause most cases of hepatitis. The type of hepatitis is named for the virus that causes it; for example, hepatitis A, hepatitis B or hepatitis C. Drug or alcohol use can also cause hepatitis. In other cases, your body mistakenly attacks healthy cells in the liver. Some people who have hepatitis have no symptoms. Others may have Loss of appetite Nausea and vomiting Diarrhea Dark-colored urine and pale bowel movements Stomach pain Jaundice, yellowing of skin and eyes Some forms of hepatitis are mild, and others can be serious. Some can lead to scarring, called cirrhosis, or to liver cancer. Sometimes hepatitis goes away by itself. If it does not, it can be treated with drugs. Sometimes hepatitis lasts a lifetime. Vaccines can help prevent some viral forms.
