EGD (Upper Endoscopy) Prep

EGD (Upper Endoscopy) Prep Explained

An EGD (upper endoscopy) uses a flexible scope to examine the esophagus, stomach, and upper small intestine while you are sedated. Because fasting is required and some diabetes and GLP-1 medications affect stomach emptying, preparation helps ensure the procedure is performed safely and accurately.

Important Things to Know

  • Continue all aspirin and anti-inflammatory medications including ibuprofen, Motrin, Aleve, naproxen, Naprosyn, sulindac, piroxicam, Feldene, indomethacin, diclofenac, and Voltaren. Tylenol (acetaminophen) is also safe to continue.
  • If you take a prescribed blood thinner you will need holding instructions from our office.
  • Arrange to have a driver take you home after the procedure. You will not be allowed to drive after receiving sedation.

Timing & Schedule

Preparation focuses on fasting and medication planning in the days leading up to your procedure. You’ll follow specific dietary guidelines beforehand and adjust diabetes or GLP-1 medications as instructed. Detailed instructions and exact timing are provided below.

Instructions:
Step 1.
If you have diabetes or are taking medications for weight loss
  • Fasting (going without food) is required for this procedure, monitor your blood sugar and follow these directions:
    • Insulin Pump: Leave on, if you have questions refer to your endocrinologist.
    • Long-acting Insulin: Do not take the morning of your procedure.
    • Short-acting insulin: dose as necessary with blood sugar monitoring. Oral diabetic medication: do not take the morning of your procedure.
    • GLP1: Do not take 7-days prior to your procedure (may take day after).
    • If you are concerned about your blood sugar dropping, consider purchasing glucose tablets.
Step 2.
If you take Ozempic (Semaglutide), Mounjaro (Trizepatide) or ANY GLP-1

The Day Before Your Procedure

  • Do not eat any solid food the ENTIRE day before your procedure. You may consume clear fluids including juice (apple, grape, strained orange, strained lemonade), tea, coffee (no milk or creamer), soft drinks, sports drinks (Gatorade, Powerade), clear broth or bouillon, Jell-O, and popsicle only.

Day of Your Procedure

  • DO NOT drink ANYTHING 4 hours prior to your procedure. This also means NO water other than to take your medications – this is very important. Drinking within 4 hours before your procedure may result in delay or cancellation of your procedure.
Step 3.
If you DO NOT take Ozempic (Semaglutide), Mounjaro (Trizepatide) or ANY GLP-1

The Day of Your Procedure

  • Do not eat any solid food for 8 hours prior to the procedure. You may consume clear fluids including juice (apple, grape, strained orange, strained lemonade), tea, coffee (no milk or creamer), soft drinks, sports drinks (Gatorade, Powerade), clear broth or bouillon, Jell-O, and popsicles.
  • DO NOT eat or drink ANYTHING 4 hours prior to your procedure. This also means NO water other than to take your medications – this is very important. Drinking less than 4 hours before your procedure may result in delay or cancellation of your procedure.

Additional Details
Medication:
  • There are different instructions depending on the medications you take, please read all instructions carefully.
  • PLEASE do not drink water or anything while driving to your appointment or waiting for your appointment – we need your stomach empty to safely use sedation.
  • You may not remember your conversation with your doctor after your procedure – we STRONGLY recommend your driver stays IN our facility to speak with the doctor after your test.

Your procedure time will be approximately 90 minutes from the scheduled check-in time to discharge for procedures in the Meridian, Boise, and Canyon County Endoscopy Centers. Please coordinate with your driver to alleviate delays in discharge. Patients’ stay times for hospital procedures may be longer.

We cannot be responsible for your valuables (watches or various jewelry items). Please leave them at home.

Bring all insurance cards and a photo ID with you. Please check with your insurance company regarding prior authorization. Fee for services is required at time of check-in. Please be prepared to make a payment.

IGA recognizes that your time is valuable, and so is ours. If you need to cancel or reschedule an appointment, please do so more than 48 business hours prior to your scheduled appointment arrival time at 208-343-6458. Late cancellations and no shows may be assessed a $200 fee.
