Learn about gastroscopy

This short animation explains why gastroscopy is done and how it can investigate (and sometimes treat) problems in the oesophagus, stomach and small intestine.

The basics

What’s gastroscopy?

Gastroscopy is a diagnostic test that allows your doctor to look inside your oesophagus (the pipe that leads from your mouth to your stomach), your stomach, and your duodenum (top part of your small intestine).

While you’re sedated, your doctor passes a thin tube (with a camera on the end) called a gastroscope into your stomach through your mouth. Images from the camera are magnified and viewed on a monitor.

Your doctor can pass special small biopsy forceps through the gastroscope to take tissue samples for diagnosis. It's considered a very safe and precise way of investigating your oesophagus, stomach and duodenum.

Why is it done?

To check for abnormalities in your oesophagus, stomach and duodenum.

Common reasons include:

  • abdominal or chest pain
  • reflux
  • difficulty swallowing
  • persistent nausea and vomiting
  • abdominal bloating
  • abnormal findings from imaging or blood tests.

These symptoms can be due to a wide range of disorders, including:

  • oesophageal stricture (narrowing or tightening of oesophagus)
  • hiatal hernia (where a part of your stomach gets pushed up into the chest cavity)
  • stomach polyps
  • an ulcer
  • bleeding in your stomach or duodenum
  • coeliac disease
  • lactose intolerance
  • inflammation of the stomach (gastritis)
  • cancer in your stomach or oesophagus.

Your doctor may also use gastroscopy as a screening tool if you have a strong family history of stomach cancer or to follow up previous treatment. Gastroscopy is usually performed as an elective procedure but sometimes it’s done as an emergency procedure to investigate acute bleeding or an obstruction.

Doctors sometimes do a gastroscopy on the same day as a colonoscopy if they think your colon should be also examined.
