Upper Endoscopy

Upper endoscopy lets your doctor examine the lining of the upper part of your gastrointestinal tract, which includes the esophagus, stomach and duodenum (first portion of the small intestine). Your doctor will use a thin, flexible tube called an endoscope, which has its own lens and light source, and will view the images on a video monitor. You might hear your doctor or other medical staff refer to upper endoscopy as upper GI endoscopy or EGD.

How Should I Prepare for the Procedure?

An empty stomach allows for the best and safest examination, so you should have nothing to eat or drink, including water, for approximately six hours before the examination. You doctor will tell you when to start fasting.

What Can I Expect During Upper Endoscopy?

Your doctor might start by spraying your throat with a local anesthetic or by giving you a sedative to help you relax. You will lie on your side, and your doctor will pass the endoscope through your mouth and into the esophagus, stomach and duodenum. The endoscope doesn't interfere with your breathing. Most patients consider the test only slightly uncomfortable, and many patients fall asleep during the procedure.

What Happens After Upper Endoscopy?

You will be monitored until most of the effects of the medication have worn off. Your throat might be a little sore, and you might feel bloated because of the air introduced into your stomach during the test. You will be able to eat after you leave unless your doctor instructs you otherwise.

Your doctor generally can tell you your test results on the day of the procedure; however, the results of some tests might take several days.

In you received sedatives, you won't be allowed to drive after the procedure even though you might not feel tired. You should arrange for someone to accompany you home because the sedatives might affect your judgment and reflexes for the rest of the day.

Call the GI nurse at 545-8000 if you have any questions about your upcoming procedure.
