Most liver damage caused by viral hepatitis is recoverable. Viral hepatitis is mainly categorized into acute hepatitis, chronic hepatitis, liver failure, cholestatic hepatitis, and cirrhosis due to hepatitis. Among these, acute hepatitis generally only requires symptomatic treatment. If patients rest adequately and maintain a light diet, they can fully recover back to normal after timely treatment; for chronic hepatitis, in addition to the symptomatic treatments mentioned, antiviral treatment should also be considered.

If chronic hepatitis is not well managed, cirrhosis may develop. Patients with cirrhosis tend to have relatively severe liver damage and are prone to recurrence, making the treatment less effective. In critical cases, such as patients with liver failure, the liver damage is very severe, and the treatment and prognosis are generally poorer.
