What Is the Prep for an Endoscopy? Updated 2025 Patient Overview | Bestwrites
If you have an upcoming endoscopy, understanding the preparation steps can help you feel more confident and avoid delays. Because doctors need a clear view of your digestive tract, the foods you eat, the liquids you drink, and the medications you take before the test all matter. This updated 2025 Patient Overview from Bestwrites explains exactly what the prep is for an endoscopy, including diet rules, fasting guidelines, medication instructions, and day-of expectations so you can prepare safely and correctly.
Why Endoscopy Prep Is Necessary
An upper endoscopy is a procedure where a thin flexible tube with a camera is placed through your mouth and into your:
Esophagus
Stomach
Upper small intestine
Doctors use this exam to evaluate symptoms such as acid reflux, nausea, bleeding, swallowing problems, and stomach pain. Proper prep ensures:
A clear view for the doctor
Lower risk during sedation
Accurate results
A smoother, shorter procedure
No need to repeat the test
In 2025, prep guidelines are more standardized, making the process easier to follow.
2025 Endoscopy Prep: Step-by-Step Guide
These steps cover what most clinics require in 2025. Your doctor may adjust instructions for your health conditions, so always review your specific prep sheet.
1. Provide Your Complete Medical History
Before the procedure, your care team will ask about:
Current medications
Allergies
Ongoing medical conditions
Heart, lung, or bleeding disorders
Diabetes
Past surgeries
Reactions to anesthesia
This information helps determine the safest sedation plan and whether certain medications need to be paused.
2. Follow Medication Instructions Carefully
In 2025, medication management is a major part of endoscopy prep. Your doctor may recommend changes to:
Blood thinners: Often adjusted or paused for a short period
Diabetes medications: Doses may be changed because of fasting
Iron supplements: Frequently stopped 5–7 days ahead
NSAIDs (ibuprofen, naproxen): Sometimes limited
Heart medications: Usually taken with a small sip of water
Never make changes without direct medical guidance. Some medications must not be skipped without approval.
Diet Rules for Endoscopy Prep (2025 Update)
Most patients follow a light, low-fiber diet the day before fasting begins. This helps reduce stomach contents and lowers the risk of nausea.
Foods You CAN Eat
Eggs
Yogurt (if approved)
White toast
Plain pasta or white rice
Clear soups and broth
Bananas
Applesauce
These foods break down easily and leave minimal residue in the stomach.
Foods You Should AVOID
Raw vegetables
Salads
Whole grains
Nuts, seeds, beans
Spicy or fried foods
Heavy meals late in the day
Red or purple foods or drinks
Avoiding these foods ensures better visibility during the exam.
2025 Fasting Requirements
Fasting is one of the most important steps in preparing for an endoscopy.
Stop eating all solid food 8–12 hours before the procedure.
This includes candy, gum, and snacks.
Clear liquids are usually allowed until 2–4 hours before your appointment.
Approved clear liquids:
Water
Clear electrolyte drinks
Apple juice
Tea or black coffee (no milk or cream)
Clear broth
Avoid dairy, smoothies, soda, or cloudy drinks of any kind.
Your doctor will tell you the exact cutoff times based on your scheduled start time.
Hydration Guidelines
In 2025, clinics emphasize hydration as part of prep. Drinking clear liquids before your cutoff time:
Helps prevent dizziness
Makes IV placement easier
Reduces nausea
Improves overall comfort
Stay well hydrated until you begin your fasting window.
3. Arrange Transportation Home
Because sedation affects reflexes, memory, and decision-making, you cannot drive yourself home. You must arrange:
A responsible adult to pick you up
Someone to stay with you for several hours if your clinic requires it
If no driver is available, the procedure may be postponed for safety reasons.
What to Expect on Endoscopy Day
Arrive 20–30 minutes early and follow these guidelines:
Wear comfortable clothing
Remove jewelry
Bring your ID, insurance card, and medication list
Follow fasting rules exactly
During the procedure:
A nurse places an IV.
You receive sedation to help you relax.
The doctor guides the endoscope through your mouth.
The exam lasts about 10–20 minutes.
You rest in recovery until you are fully alert.
Most patients experience little to no discomfort.
After the Endoscopy
Common mild symptoms include:
Sore throat
Bloating
Sleepiness
These typically disappear within a few hours.
Post-Procedure Instructions

Move to soft, easy foods
