Preparing for Gastroscopy | Recommended Tips

Gastroscopy is a common medical procedure that involves inserting a thin, flexible tube with a camera (called an endoscope) down the throat to examine the upper digestive system.

It is used to diagnose and treat various conditions, such as ulcers, inflammation, and even cancer. While it may sound intimidating, gastroscopy is usually a quick and painless procedure.

If you are scheduled for a gastroscopy, here are some recommended tips to help you prepare for the procedure.


Before the Procedure

Consult with Your Doctor

It is essential to consult with your doctor before undergoing a gastroscopy. They will provide you with specific instructions on how to prepare for the procedure based on your medical history and any medications you may be taking.

Be sure to inform your doctor if you have allergies, bleeding disorders, or pregnant.


Fast Before the Procedure

To ensure a clear view of the digestive system, it is necessary to fast for at least 6 hours before the procedure. This means no food for six hours or fluids for four hours.

Your doctor will provide you with specific instructions on when to stop eating and drinking before the procedure.


Arrange for Transportation

Gastroscopy is usually performed under sedation, which can make you drowsy and dizzy.

It is essential to arrange for transportation home after the procedure, as you will not be able to drive yourself.


During the Procedure

Wear Loose-Fitting Clothing

On the day of your gastroscopy, wear loose-fitting clothing that is comfortable and easy to remove.

This will make it easier for the medical staff to attach monitoring devices and perform the procedure.


Communicate with Your Doctor

During the procedure, you may feel some discomfort, such as gagging or bloating.

It is important to communicate any discomfort or concerns with your doctor so they can adjust accordingly.


After the Procedure

Rest and Take It Easy

After the procedure, you may feel drowsy or slightly bloated. It is essential to rest and take it easy for the remainder of the day.

Avoid strenuous activities, driving, or operating heavy machinery until the effects of sedation wear off completely.


Follow Post-Procedure Instructions

Your doctor will provide you with specific post-procedure instructions, such as when you can resume eating and drinking, when to take any prescribed medications, and how to care for the insertion site.

It is crucial to follow these instructions carefully to ensure a smooth recovery and avoid any complications.



Gastroscopy is an important medical procedure that can help diagnose and treat various digestive system conditions. By following these recommended tips, you can prepare yourself physically and mentally for the procedure, making it as comfortable and successful as possible.

Remember to always consult with your doctor if you have any concerns or questions about the procedure.
