2. Cirrhosis: Usually develops from chronic hepatitis, leading to changes in liver structure and impaired function.

4. Fatty liver: Caused by excessive accumulation of fat in the liver, which can progress to cirrhosis in severe cases.
5. Gallstones: Common in adults, which may lead to complications such as cholecystitis and cholangitis.
6. Cholecystitis: Caused by gallstones and other factors, manifested as right upper abdominal pain and other symptoms.
These diseases can seriously affect patients' health and therefore require timely medical treatment.
