Frequently Asked Questions (FAQ): Preparing for Your Upper Endoscopy (EGD)

1. What is an upper endoscopy (EGD)?

An upper endoscopy (also called EGD) is a procedure that allows your doctor to examine the esophagus, stomach, and upper small intestine (duodenum) using a thin, flexible tube with a camera. It helps diagnose problems such as acid reflux, ulcers, bleeding, swallowing issues, and other upper GI conditions.

2. How do I prepare for my procedure?

You must have an empty stomach for the procedure.

  • Do not eat or drink anything (including water) for at least 6–8 hours before your appointment.

  • This ensures a clear view and reduces the risk of vomiting or aspiration during the test.

  • Your doctor will give you specific instructions based on your scheduled time.

3. Can I take my regular medications?

  • Blood pressure and heart medications: Usually, they may be taken with a small sip of water in the morning of your procedure.

  • Diabetes medications (insulin or pills): You will receive special instructions — often to hold or adjust the dose since you won’t be eating.

  • Blood thinners (like aspirin, Plavix, Eliquis, or Coumadin): Tell your doctor. You may need to stop these a few days before the procedure.
    ➡️ Do not stop any prescribed medication without your doctor’s approval.

4. Do I need to stop eating certain foods before my EGD?

The day before your procedure, eat light meals and avoid heavy, greasy, or spicy foods. Stop eating solid foods after midnight. Only clear liquids may be allowed until 6–8 hours before the test.

5. What are clear liquids?

Clear liquids include:

  • Water

  • Clear broth (chicken, beef, or vegetable)

  • Apple juice or white grape juice

  • Gatorade or Powerade (avoid red, blue, or purple)

  • Tea or coffee (no milk or cream)

  • Lemonade or clear sodas

Avoid red or purple liquids — they can look like blood during the procedure.

6. Can I smoke or chew gum before the procedure?

No. Avoid smoking, chewing gum, or sucking on candy for at least 6 hours before your procedure — these can increase stomach secretions and make the test more difficult.

7. Will I be asleep during the procedure?

Yes, most patients receive sedation or anesthesia to help them relax or sleep through the procedure. You will not feel discomfort or remember much of the procedure.

8. Do I need someone to drive me home?

Yes. Because you’ll receive sedation, you must have a responsible adult drive you home after the procedure.
You cannot drive, use rideshare alone, or return to work for the rest of the day.

9. What happens during the procedure?

  • You’ll lie on your left side while a nurse monitors your vital signs.

  • A mouthguard will be placed to protect your teeth and the scope.

  • The doctor will gently insert the endoscope through your mouth into your esophagus, stomach, and duodenum.

  • Air may be used to expand the area for better visibility.

  • The doctor may take biopsies (small tissue samples) — this is painless.
    The procedure usually takes 10–15 minutes.

10. What can I expect after the procedure?

  • You’ll rest in a recovery area for about 30–60 minutes until the sedation wears off.

  • Your throat may feel sore or bloated from air introduced during the procedure — this improves in a few hours.

  • You can eat and drink once fully awake, unless instructed otherwise.

11. When will I get my results?

  • Preliminary findings are usually discussed the same day.

  • If biopsies are taken, results may take 5–7 business days.
    Our staff will contact you or discuss results at your follow-up visit.

12. What symptoms should I report after the procedure?

Call your doctor or go to the emergency room if you experience:

  • Severe abdominal pain or persistent vomiting

  • Difficulty swallowing

  • Fever or chills

  • Chest pain or shortness of breath

  • Black or bloody stools

These are rare but may indicate complications.
