Endoscopy  allows us to investigate the upper digestive tract, including the esophagus, stomach and duodenum, and identify conditions like acid reflux, Barrett’s esophagus, ulcers, gastritis, celiac disease, and other forms of inflammation. Endoscopy can also be helpful in excluding acid reflux in people who suffer from small intestinal bacterial overgrowth (SIBO).

Place of Procedure:

Georgetown University Hospital
Division of Gastroenterology
