John Zak III, M.D.
Gastroenterology is the branch of medicine whereby the digestive system and its disorders are studied. Diseases affecting the gastrointestinal tract, which includes the organs from mouth to anus, along the alimentary canal, are the focus of this specialty.
Hepatology encompasses the study of the liver, pancreas, and biliary tree and is traditionally considered a sub-specialty.
