Upper GI Endoscopy (Gastroscopy)

What is an Upper GI Endoscopy?

An Upper GI Endoscopy, also called a gastroscopy, is a simple procedure that allows your doctor to look at the inside of your oesophagus (food pipe), stomach, and the first part of the small intestine. A thin, flexible tube with a tiny camera and light is passed gently through the mouth and into the stomach.

This test can help us understand the cause of symptoms such as:

  • Heartburn or indigestion
  • Upper abdominal discomfort
  • Nausea or vomiting
  • Difficulty swallowing
  • Reflux symptoms that are not settling
  • Unexplained bleeding

Sometimes a small sample of tissue (biopsy) may be taken during the procedure. This is usually painless.

Before Your Procedure

To get the clearest view, your stomach needs to be empty.

You may be asked to:

  • Stop eating for several hours before the procedure
  • Stop drinking at the time advised by our office
  • Let us know about any allergies
  • Tell us if you have diabetes
  • Tell us if you take blood thinners or any regular medication
  • Arrange for someone to take you home if you will be having sedation

Please note: Your doctor or nurse will give you personalised instructions. It is very important to follow those exact directions.

What to Expect During the Procedure

When you arrive, our team will welcome you, review your medical details, and answer any final questions you may have.

During the procedure:

  • Your throat may be numbed with a spray
  • You may also receive sedation to help you feel relaxed and comfortable
  • The endoscope is passed gently through the mouth and into the stomach
  • A little air may be used so the doctor can see clearly
  • The procedure itself is usually quite short, although you may be with us a little longer for preparation and recovery

You may notice:

  • A little fullness or bloating
  • The urge to burp

Most patients tolerate the procedure well, and our team will be right there with you throughout.

Afterwards:

  • You will rest in recovery
  • Your throat may feel mildly sore for a short time
