What is Hepatitis?

---

Hepatitis means inflammation of the liver. Inflammation is one of the body's normal responses to infection and toxic stimuli.

This response occurs when the liver is threatened, not just by viruses, but by some chemicals, too much alcohol and other drugs. The liver defends itself by trying to destroy or seal off viruses, dangerous substances or damaged liver tissue.

This inflammatory response can protect against an infection or substance but can also cause damage in itself. There are different viruses that can cause hepatitis and each of them can result in different illnesses and need different treatments.
