Illustration of the liver

Also called: Hepatic disease

Your liver is the largest organ inside your body. It is also one of the most important. The liver has many jobs, including changing food into energy and cleaning alcohol and poisons from the blood. Your liver also makes bile, a yellowish-green liquid that helps with digestion.

There are many kinds of liver diseases. Viruses cause some of them, like hepatitis A, hepatitis B and hepatitis C. Others can be the result of drugs, poisons or drinking too much alcohol. If the liver forms scar tissue because of an illness, it's called cirrhosis. Jaundice, or yellowing of the skin, can be one sign of liver disease.

Like other parts of your body, cancer can affect the liver. You could also inherit a liver disease such as hemochromatosis.
