What is Hepatitis?

Hepatitis is inflammation of the liver, which can be caused by viral infections (hepatitis A, B, C, D, or E), excessive alcohol use, certain medications, or autoimmune conditions. Symptoms can include fatigue, nausea, abdominal pain, and jaundice (yellowing of the skin and eyes), though some forms cause no symptoms at all, especially early on.

Treatment and outlook depend significantly on the specific type and cause of hepatitis — some forms, like hepatitis A, typically resolve on their own, while others, like hepatitis B and C, may need specific antiviral treatment and long-term monitoring.
