Esophagogastroduodenoscopy (EGD) is a test to examine the lining of the esophagus, stomach, and first part of the small intestine.
When You’re in the Hospital
EGD is done with an endoscope. This is a flexible tube with a camera at the end.
During the procedure:
- You will receive medicine into a vein (IV).
- The scope will be inserted through the esophagus (food pipe) to the stomach and first part of the small intestine (duodenum). The air will be put through the endoscope to make it easier for the doctor to see.
- If needed, biopsies will be taken through the endoscope. Biopsies are tissue samples that are looked at under the microscope.
The test will last for about 5 to 20 minutes.
Right After the Test
You will be taken to an area to recover right after the test. You may wake up and not remember how you got there.
The nurse will check your blood pressure and pulse. Your IV will be removed.
Your doctor will come talk to you and explain the results of the test.
- Ask to have this information written down, as you may not remember what you were told later on.
- Final results for any tissue biopsies that were done may take up to 1 to 3 weeks.
Medicines you were given can change the way you think and make it harder to remember for the rest of the day.
As a result, it is NOT safe for you to drive a car or find your own way home.
You will not be allowed to leave alone. You will need to ask a friend or family member to take you home.
Eating and Drinking
You will be asked to wait 30 minutes or more before drinking. Try small sips of water first. When you can do this easily, you can begin with small amounts of solid foods.
You may feel a little bloated from air pumped into your stomach, and burp or pass gas more often over the day.
If your throat is sore, gargle with warm, salty water.
The Rest of the day
DO NOT plan to return to work for the rest of the day. It is not safe to drive or handle tools or equipment.
You should also avoid making important work or legal decisions for the rest of the day, even if you believe your thinking is clear.
Keep an eye on the site where the IV fluids and medicines were given. Watch for any redness or swelling. You can place a warm wet washcloth over the area.
Ask your doctor which medicines or blood thinners you should start taking again and when to take them.
If you had a polyp removed, your health care provider may ask you to avoid lifting and other activities for up to 1 week.

- Black, tarry stools
