Hepatology is a branch of medicine concerned with the study, prevention, diagnosis and management of diseases that affect the liver, gallbladder, biliary tree and pancreas. The term hepatology is derived from the Greek words “hepatikos” and “logia,” which mean liver and study, respectively. Hepatitis affects millions of individuals globally and is associated with several poor outcomes including liver transplant and liver cancer. In particular, hepatitis B and hepatitis C are major causes of liver cancer, while alcohol abuse has been linked to conditions such as cirrhosis and other serious complications. The conditions hepatologists deal with most frequently are viral hepatitis and alcohol-related liver disease.
