How To Prepare
Before having an upper gastrointestinal
endoscopy, tell your doctor if you:
- Are allergic to any medicines, including
anesthetics.
- Are taking any medicines.
- Have bleeding
problems or take blood-thinning medicine, such as warfarin (Coumadin).
- Have heart problems.
- Are or might be
pregnant.
- Are
diabetic and take insulin.
- Have
had surgery or radiation treatments to your esophagus, stomach, or the upper
part of your small intestine.
You will usually be asked to sign a consent form before the test.
Talk to your doctor about any concerns you have regarding the need for the
test, its risks, how it will be done, or what the results will mean. To help
you understand the importance of this test, fill out the
medical test
information form
(What is a PDF document?).
You may be asked to stop taking aspirin products or iron
supplements 7 to 14 days before the test. If you take blood-thinning medicines
regularly, discuss with your doctor how to manage your
medicine.
Do not take sucralfate (Carafate) or antacids the day of the test.
These medicines can interfere with your doctor's ability to view the
gastrointestinal tract.
If biopsy samples are taken or polyps are removed during the test,
bleeding may also occur. This bleeding usually stops on its own without
treatment. To reduce this risk, avoid aspirin and
nonsteroidal anti-inflammatory drugs (NSAIDs) for
several days before the endoscopy. If you take blood-thinning medicine, you may
be instructed to stop the medicine temporarily before the test.
Do not eat or drink anything for 6 to 8 hours before the test. An
empty stomach helps your doctor see your stomach clearly during the test. It
also reduces your chances of vomiting. If you vomit, there
is a small risk that your stomach contents could enter your lungs (aspiration).
If the test is done in an emergency, a tube may be
inserted through your nose or mouth to empty your stomach.
Before the test, you will put on a hospital gown; if you are
wearing dentures, jewelry, contact lenses, or glasses, remove them. For your
own comfort, empty your bladder before the test begins.
Arrange to have someone take you home after the test because you
will be given a sedative before the test.
