What is a gastroscopy?

A gastroscopy is a diagnostic test of the upper gastrointestinal tract, including the oesophagus, stomach and duodenum. The test involves the insertion of an endoscope (long, thin telescope) down through the mouth and throat, in order to observe any growths, blockages or inflammation.

If you are experiencing symptoms such as abdomen pain, vomiting or difficulty swallowing, a gastroscopy may be ordered to check for:

  • Oesophagitis - inflammation of the oesophagus, which will appear as redness along the oesophageal lining
  • Duodenal and stomach ulcers
  • Inflammation of the duodenum or stomach
  • Cancer of the stomach and oesophagus
