Upper Endoscopy (EGD)

An upper endoscopy or EGD (esophagogastroduodenoscopy) is a test performed with an endoscope, which is a long, flexible tube that is thinner than most food you swallow.  The test allows your physician to examine the lining of the esophagus, stomach and duodenum (the first portion of the small intestine).  Doctors perform an upper endoscopy to help find the cause of symptoms such as persistent heartburn, bleeding, nausea and vomiting, and problems swallowing.  An EGD is also performed to diagnose GERD (gastroesophageal reflux disease), ulcers, Celiac Disease, or Barrett’s Esophagus.
