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. Over two billion individuals have been infected with hepatitis B at some point and around 350 million people are persistent carriers. With widespread vaccination and blood screening, the incidence of hepatitis B has significantly decreased. However, hepatitis B and hepatitis C are accountable for up to 80% of liver cancer cases. In addition to these types of hepatitis, the primary conditions encountered by hepatologists deal include viral hepatitis and alcohol-related liver disease.
