This information will help you get ready for your upper endoscopy.
An upper endoscopy is an exam of your esophagus (food pipe), stomach, and the first part of your small intestine. During your upper endoscopy, your doctor will use a flexible tube called an endoscope to see the inside of your esophagus, stomach, and small intestine on a video screen.
Your doctor can take a small sample of tissue (do a biopsy) or remove a polyp (growth of tissue) during your procedure.Back to top
1 Week Before Your Procedure
Ask about your medications
You may need to stop taking some of your medications before your procedure. Talk with your doctor about which medications are safe for you to stop taking. We have included some common examples below.
Anticoagulants (blood thinners)
If you take a blood thinner, such as to treat blood clots or to prevent a heart attack or stroke, ask the doctor who prescribes it for you when to stop taking it. See below for examples of common blood thinners.

There are others, so check with your doctor if you’re not sure.
Medications for diabetes
If you take insulin or other medications for diabetes, you may need to change the dose. Ask the doctor who prescribes your diabetes medication what you should do the day before and the morning of your procedure.
If you take metformin (such as Glucophage® or Glumetza®) or a medication that contains metformin (such as Janumet®), don’t take it the day before or the day of your procedure.
Tell your doctor if you have an AICD
Tell your Memorial Sloan Kettering (MSK) doctor if you have an automatic implantable cardioverter-defibrillator (AICD). If you have this device, you will need to have your procedure done at Memorial Hospital (MSK’s main hospital).
Get a letter from your doctor, if needed
- If you have an AICD, you will need to get a clearance letter from your cardiologist (heart doctor) before your procedure.
- If you’ve had chest pain, dizziness, trouble breathing that’s new or worse, or have fainted in the last 6 weeks, you will need to get a clearance letter from your doctor before your procedure.
Your MSK doctor’s office must receive your clearance letter at least 1 day before your procedure.
Arrange for someone to take you home
You must have a responsible care partner take you home after your procedure. A responsible care partner is someone who can help you get home safely and report concerns to your healthcare providers, if needed. Make sure to plan this before the day of your procedure.
If you don’t have a responsible care partner to take you home, call one of the agencies below. They’ll send someone to go home with you. There’s usually a charge for this service, and you’ll need to provide transportation. It’s okay to use a taxi or car service, but you must still have a responsible care partner with you.

3 Days Before Your Procedure
An endoscopy nurse will call you between 8:00 am and 6:00 pm 3 days before your procedure. They will review the instructions in this guide with you and ask you questions about your medical history. The nurse will also review your medications and tell you which medications to take the morning of your procedure.
Use the space below to write them down.

If you need to cancel your procedure, call the doctor who scheduled it for you.

What to expect
Once you arrive
Once you arrive, you will be asked to state and spell your name and date of birth many times. This is for your safety. People with the same or similar names may be having procedures on the same day.
After changing into a hospital gown, you will meet your nurse. They will place an intravenous (IV) catheter into one of your veins, usually in your hand or arm. The IV will be used to give you anesthesia (medication to make you sleep) during your procedure. You may also get fluids through the IV before your procedure.
You will talk with your doctor before your procedure. They will explain the procedure and answer your questions.
During your procedure
When it’s time for your procedure, you will be brought into the procedure room and helped onto an exam table. You will be attached to equipment to monitor your heart, breathing, and blood pressure. You will also receive oxygen through a thin tube that rests below your nose. A mouth guard will be placed over your teeth to protect them.
You will get anesthesia through your IV, which will make you fall asleep. Once you’re asleep, your doctor will pass the endoscope through your mouth, down your esophagus, into your stomach, and into your small intestine. Your doctor will take biopsies if needed, then remove the endoscope.Back to top
After Your Procedure
Your nurse will continue to monitor your heart, breathing, and blood pressure. You may feel soreness in your throat. If you do, it should go away in 1 to 2 days.
Once you’re fully awake, your nurse will remove your IV. If you have someone waiting with you, your nurse will explain your discharge instructions to both of you before you go home.
Don’t drink alcoholic drinks for 24 hours after your procedure.Back to top
