What is a Gastroenterologist?

A gastroenterologist is a doctor who specializes in the diagnosis and treatment of digestive disorders, such as gastroesophageal reflux disease (GERD), of the gastrointestinal tract, also called the digestive tract. This organ system includes: the esophagus, liver, pancreas and biliary, small intestine and colon.

The AGA Institute administers the practice, research and educational programs of the organization.

The mission of the American College of Gastroenterology (ACG) is to advance the medical treatment and scientific study of gastrointestinal disorders.
