Get Ready for Your Endoscopy

Preparing for an endoscopy is an important step toward a safe and effective procedure. Whether your gastroenterologist has recommended an endoscopy to investigate persistent heartburn, abdominal pain, difficulty swallowing, or other digestive symptoms, knowing what to expect can help you feel more comfortable and confident.

At Abu Hammour Gastroenterology Center in Dubai Healthcare City, we believe that proper preparation, clear instructions, and expert care are essential parts of your digestive health journey.

What Is an Endoscopy?

An upper gastrointestinal (GI) endoscopy is a medical procedure that allows a gastroenterologist to examine the lining of your esophagus, stomach, and the first part of your small intestine using a thin, flexible tube with a camera.

Your doctor may recommend an endoscopy to investigate:

• Persistent heartburn or acid reflux

• Ongoing abdominal pain or discomfort

• Difficulty swallowing

• Unexplained nausea or vomiting

• Persistent indigestion

• Suspected ulcers, inflammation, or gastrointestinal bleeding

An endoscopy can help identify digestive conditions and guide your doctor in recommending appropriate treatment.

How to Prepare for Your Endoscopy

Following your doctor's instructions carefully can help ensure that your procedure goes smoothly. Preparation may vary depending on your medical history, medications, and whether sedation will be used.

1. What to Eat Two Days Before Your Endoscopy

For a routine upper GI endoscopy, a special diet two days beforehand is not always necessary. However, your doctor may recommend dietary changes depending on your condition and the type of procedure planned.

If your healthcare team advises a low-fiber diet, consider the following options.

Foods generally suitable for a low-fiber diet

• White rice and plain pasta

• White bread and plain crackers

• Skinless chicken and fish

• Eggs

• Clear soup or broth

• Well-cooked vegetables, if permitted

Foods to avoid if instructed to follow a low-fiber diet

• Whole grains and bran

• Nuts and seeds

• Raw vegetables and salads

• Fruits with skins or seeds

• Beans and other high-fiber foods

Please note: These dietary restrictions are not required for every upper endoscopy. If you are having a colonoscopy or a combined gastroscopy and colonoscopy, your preparation will be different and may require a low-fiber diet, clear liquids, and bowel-cleansing medication.

2. Follow Your Fasting Instructions

Fasting is essential before an upper GI endoscopy because food or liquid in the stomach can affect the examination and increase the risk of complications, particularly during sedation.

Here is a general guide:

Two days before

Eat your usual diet unless your doctor recommends a special diet. If instructed to follow a low-fiber diet, choose foods approved by your healthcare team.

The day before

Follow your clinic's dietary instructions. A routine upper endoscopy does not always require an all-day clear-liquid diet.

Six to eight hours before

Many patients are instructed to stop eating solid food at least 6–8 hours before the procedure. Clear liquids may sometimes be allowed until two hours beforehand, depending on your clinical circumstances and sedation plan. Your clinic may require a longer fasting period.

Important: Always follow the exact fasting times provided by your endoscopy team. Do not assume that water is permitted until two hours before your appointment unless your healthcare team confirms this.

3. Review Your Medications

Inform your gastroenterologist about all medications, vitamins, and supplements you take. This is particularly important if you use:

• Blood thinners

• Diabetes medications or insulin

• Medicines that slow stomach emptying, including GLP-1 medications

• Iron supplements or other medicines your doctor asks you to review

Do not stop or adjust any medication without medical advice. Your doctor will explain which medicines you should take or temporarily withhold before the procedure.

4. Share Your Medical History

Before your endoscopy, tell your healthcare team about any existing medical conditions, allergies, previous reactions to anesthesia or sedation, and any history of bleeding problems.

If you have diabetes, delayed stomach emptying, or other conditions that may affect fasting or sedation, your preparation instructions may need to be adjusted.

5. Arrange Transportation if Sedation Is Planned

Sedation may be used to help you feel relaxed and comfortable during your endoscopy.

If you receive sedation, arrange for a responsible adult to accompany you home. Avoid driving, operating machinery, drinking alcohol, or making important decisions until the effects have worn off and your healthcare team confirms it is safe.

6. Ask Questions Before Your Appointment

If you are unsure about fasting, medications, dietary restrictions, or what to expect during the procedure, contact your clinic before your appointment.

Following the correct instructions can help prevent unnecessary delays and support a smoother procedure.

What Happens During an Endoscopy?

During an upper GI endoscopy, you will be positioned comfortably while your healthcare team monitors you as needed.

The gastroenterologist gently guides a thin, flexible endoscope through your mouth and into your upper digestive tract. A camera transmits images of the lining of your esophagus, stomach, and the first part of your small intestine.

If necessary, the doctor may collect small tissue samples, known as biopsies, for further examination.

The procedure is generally brief, although its duration varies depending on the findings and whether additional procedures are needed.

What to Expect After Your Endoscopy

After the procedure, you may rest in a recovery area while your healthcare team monitors you, particularly if you received sedation.

You may experience mild, temporary symptoms such as:

• Sore throat: Mild throat discomfort may occur after the procedure.

• Bloating or gas: Temporary discomfort may result from air introduced during the examination.

• Drowsiness: Sedation may make you sleepy for several hours.

Your doctor will explain the findings, any biopsy results that require follow-up, and the next steps in your care.

Follow the instructions provided regarding eating, drinking, medications, and returning to your normal activities.

Seek urgent medical attention if you experience severe or worsening abdominal or chest pain, difficulty breathing, vomiting blood, or black, tarry stools after the procedure.

Why Is Proper Preparation Important?

Proper preparation helps your gastroenterologist examine your upper digestive tract effectively and supports patient safety. Following fasting instructions, reviewing medications, sharing your medical history, and understanding the procedure can help reduce avoidable complications and delays.

An endoscopy can provide valuable information about digestive symptoms and help your doctor determine the most appropriate treatment.

Take the First Step Toward Better Digestive Health

Persistent digestive symptoms should not be ignored. If your gastroenterologist has recommended an endoscopy, understanding the preparation process can help you approach your appointment with greater confidence.
