Preparing for an endoscopy can feel stressful if you have never had one before. The good news is that the process is simple when you understand the steps. This 2025 Patient-Friendly Guide from Bestwrites explains exactly what the prep for an endoscopy includes, why each step matters, and what you can expect before, during, and after the procedure. Written in clear, easy-to-read language, this guide helps you feel confident and prepared.

Understanding the Purpose of an Endoscopy

An upper endoscopy, sometimes called an EGD, is a procedure that allows a doctor to look inside your esophagus, stomach, and upper small intestine using a thin, flexible tube with a camera. Doctors use endoscopies to diagnose problems such as:

• Heartburn or acid reflux

• Upper stomach pain

• Nausea or vomiting

• Swallowing problems

• Internal bleeding

• Ulcers or inflammation

To get accurate results, your stomach must be empty and your body must be prepared correctly. That is why following the prep steps is so important.

What Is the Prep for an Endoscopy? A Complete 2025 Breakdown

Below are the essential steps patients must follow before their endoscopy.

1. Share Your Medical Information

Your doctor will ask for a full medical history to plan a safe procedure. You will need to share:

• All medications you take

• Any allergies

• Medical conditions such as diabetes or heart issues

• Past surgeries

• Any problems with anesthesia in the past

This step allows the doctor to personalize your prep and avoid complications.

2. Follow Updated 2025 Medication Instructions

Your healthcare provider may ask you to adjust certain medicines. These guidelines help prevent bleeding, low blood sugar, or other risks during the procedure.

Medications often adjusted:

• Blood thinners (like warfarin, Eliquis, Plavix)

• Diabetes medications and insulin

• Iron supplements

• Anti-inflammatory drugs (ibuprofen, naproxen)

Medications were usually continued:

• Blood pressure medications

• Thyroid medication

• Most heart medications

Never stop a medication unless your doctor tells you to.

Diet Instructions for Endoscopy Prep (2025 Standards)

A light diet helps your stomach empty more easily before the procedure. Most clinics recommend switching to a low-fiber, low-fat diet the day before fasting.

Foods you CAN eat:

• Eggs

• White bread or toast

• Plain yogurt

• Rice or pasta

• Applesauce

• Bananas

• Clear soups

Foods to AVOID:

• Raw vegetables

• Whole grains

• Nuts and seeds

• Fried or fatty foods

• Spicy meals

• Red or purple liquids

Eating lightly makes prep easier and reduces discomfort.

Fasting Requirements for an Endoscopy in 2025

Fasting is one of the most important parts of preparation. It protects your lungs during sedation and ensures your stomach is fully empty.

Standard fasting guidelines:

Stop solid foods 8–12 hours before your endoscopy. This includes snacks and gum.

Clear liquids are allowed until 2–4 hours before your appointment.

Approved clear liquids include:

• Water

• Clear electrolyte drinks

• Apple juice

• Tea or black coffee (no milk)

• Clear broth

Avoid milky drinks, smoothies, soda, and anything cloudy or thick.

Your doctor will give exact times depending on when your procedure is scheduled.

Hydration Tips Before the Cutoff

Drinking clear liquids until your cutoff time helps you:

• Stay comfortable while fasting

• Avoid dehydration

• Make IV placement easier

• Recover more smoothly after sedation

Proper hydration is now considered an important part of the 2025 prep standards.

3. Arrange Required Transportation

Because you will receive sedation, you will not be allowed to drive after the procedure.

Before your appointment, arrange:

• A driver for pickup and drop-off

• Someone who can stay with you if the clinic requires supervision

If you arrive without a driver, your endoscopy may be delayed or canceled.

What to Expect on the Day of the Endoscopy

Understanding the process helps reduce stress and makes the experience easier.

1. You check in at the clinic or hospital.

2. A nurse reviews your prep steps and places an IV.

3. You meet your doctor and anesthesia provider.

4. Sedation is given to help you relax or sleep lightly.

5. The doctor gently passes the endoscope through your mouth.

6. The exam usually takes 10–20 minutes.

7. You rest in a recovery area until the sedation wears off.

Most patients feel no pain and remember little of the procedure.

After the Procedure

It is normal to have mild symptoms such as:

• A slight sore throat

• Bloating

• Sleepiness

Aftercare recommendations:

• Start with water

• Slowly add soft foods

• Avoid alcohol

• Rest for the day

• Do not drive for 24 hours

Call your doctor if you have severe pain, fever, or vomiting.
