Gastroscopy

What is gastroscopy?

Gastroscopy is a procedure used to examine the esophagus, stomach, and the upper part of the small intestine, including the duodenum. Using a soft tube that is inserted through the mouth, the doctor can view, take photographs, and collect tissue samples (biopsies).

We will ask you to complete a health declaration before the procedure, which includes questions about your general health and any current gastrointestinal symptoms. This is to ensure a safe examination.

Before your examination
You will receive an appointment letter with information on how to prepare for your examination. We ask that you complete a health declaration and review any medications you are taking. Please bring the completed health declaration to the examination. See the attached documents below for more information. If you have any questions or concerns, feel free to contact us.

You should fast for 6 hours before the procedure. It is fine to take your medications with water.

During your examination

As the procedure begins, a local anesthetic spray will be applied to your throat to reduce gag reflexes. You will lie on your left side, and a mouthguard will be placed between your teeth to protect the instrument. The procedure is not painful but may feel uncomfortable. You can breathe normally through your nose or mouth during the examination. If needed, sedative, pain-relieving, or relaxing medications can be given, but if this is the case, you should not drive that day.

After your examination

The doctor who performed the examination will, if possible, provide immediate results. If tissue samples are sent for microscopic analysis, the results will be available when the analysis is complete, up to 8 weeks after the procedure.

You can eat and drink normally once the anesthesia in your throat has worn off, approximately 1 hour after the procedure.
