Hepatology is the branch of medicine that incorporates the study of liver, gallbladder, biliary tree, and pancreas as well as management of their disorders. Diseases and complications related to viral hepatitis and alcohol are the main reason for seeking specialist advice. More than 2 billion people have been infected with Hepatitis B virus at some point in their life, and approximately 350 million have become persistent carriers.

Hepatobiliary diseases affect the liver and/or biliary tract. Common disorders include hepatitis, fatty liver, cirrhosis, cholecystitis and liver tumours.
