What is a gastroscopy?

Gastroscopy is a procedure designed to examine the lining of the upper part of the gastrointestinal (GI) tract. This includes the oesophagus (pipe that leads to your stomach), stomach and duodenum (first part of the small intestine).

Like a colonoscopy, it is performed using an endoscope - a small flexible tube with a light and a camera on the end.

What's involved?

  • Before the procedure: To prepare for the test, you will need to fast (have no food or drink) for six hours

Once you are in a state of sedation, the doctor will insert the gastroscope through your mouth and conduct the examination
