Esophagogastroduodenoscopy (EGD) is a procedure to examine the inside of the esophagus, stomach, and duodenum. During an EGD procedure, your doctor will insert a thin flexible tube with a camera and light attached into your mouth. The tube allows your doctor to view the lining of your esophagus, stomach, and duodenum. The camera will transmit images to a monitor in the procedure room so that your doctor can determine if there are any abnormalities present.
EGDs are commonly performed to diagnose or assess conditions such as:

During the procedure: Your doctor will position you on an exam table and insert the endoscope into your mouth. The endoscope transmits images to a monitor in the procedure room so that your doctor can examine the inside of your esophagus, stomach, and duodenum. The procedure typically lasts between 15-30 minutes. Most patients consider the test only slightly uncomfortable, and many fall asleep during the procedure.
After the procedure: You will be monitored for 30 minutes after the procedure is complete. Your doctor may prescribe medications or recommend dietary changes depending on the findings from your EGD.
