GI and Hepatology

Stony Brook Medicine's Division of Gastroenterology and Hepatology specializes in the prevention, diagnosis and treatment of diseases of the digestive (gastrointestinal) tract and the hepatobiliary system ("hepato" refers to the liver and "biliary" refers to the gallbladder, bile ducts or bile).

giGastroenterological diseases affect the:
  • mouth  
  • esophagus
  • stomach
  • small intestine
  • large intestine

This system works together to move food along the digestive tract, while absorbing 
nutrients and discarding waste products.

Diseases of the hepatobiliary system refer to the:

  • liver
  • gall bladder
  • bile ducts

These organs are involved with the production, storage, transport and release of bile, a secretion that prepares fats for further digestion.

Whether you have a common digestive disorder like gastroesophageal reflux disease (GERD), constipation or heartburn, or a precancerous condition like Barrett’s esophagus, or you would like to schedule a colonoscopy, Stony Brook's Gastroenterology and Hepatology is where you want to be.
