Getting Ready for Upper Gastrointestinal Endoscopy


Your doctor wants you to have an upper gastrointestinal endoscopy (EGD). This handout will tell you about the test and how to prepare for it.

Upper Gastrointestinal (GI) Endoscopy (EGD)

This is a test that looks at your esophagus (food tube), stomach and the upper part of the small intestine. A doctor will pass a viewing tube through your mouth into the stomach. This test will help find the cause of abdominal pain, heartburn, and trouble with swallowing or bleeding. An EGD is better at finding many problems in the upper GI tract than an X-ray.
During the test the doctor can also take a small piece of tissue (a biopsy) to send to the lab if we need to look at an area more closely. Doctors take biopsies for many reasons. You will not be able to feel this part of the test.

1 Week Before Test

Call Insurance

At one to two weeks before your test, you may want to call your insurance company to confirm this test is covered. They can tell you if you need an authorization to be started.

Arrange Transportation

Due to the sedation medicines, you must have a responsible adult drive you home. It is recommended that you are observed for at least 6 hours after discharge.

Health Changes

Please tell us about any major health changes, illnesses, or recent hospital stays you have had since you scheduled your test.

Blood Thinners and Diabetes Medicines

You must call the doctor who prescribes this medicine to see if you need to stop or adjust your medicine before your test. Your doctor will tell you how to safely do this.

The UW Digestive Health Center suggests using the schedule below to adjust your blood thinning medicines before your GI procedure. The list below has common blood thinning medicines. It does not include all blood thinning medicines.
