How is an EGD done?Nate Deisler
You will lie on your side during the procedure. A surgeon administers a numbing spray to your throat and inserts a mouthguard to protect your teeth. The endoscope is guided through your mouth and into the esophagus, stomach, and duodenum. Air is pumped through the endoscope to make it easier to see the lining of the esophagus, stomach, and small intestine. Images from the endoscope are viewed on a video monitor while looking for concerns and/or performing treatments.
