Hepatitis means an inflammation of the liver. Inflammation causes painful, red swelling and occurs when tissues become injured or infected. The inflammation can cause organs to not function properly.
There are different kinds of hepatitis.
Hepatitis A usually gets better within a few weeks without treatment. Usually, getting lots of rest and avoiding alcohol will be sufficient, but if symptoms persist you should see a doctor.
Hepatitis B and hepatitis C are usually not treated unless they become chronic. If chronic hepatitis B or hepatitis C causes liver failure, a liver transplant may become necessary.
