Gastroscopy

What is it?

A gastroscopy is the examination of the throat, oesophagus (gullet), stomach and duodenum by a flexible endoscope, a thin tube with a digital camera at its end. Common reasons for a gastroscopy include persistent reflux symptoms, persistent pain in the upper abdomen, food getting stuck when swallowing, suspicion of bleeding, and diagnosing coeliac disease.

Do I need one?

The most important symptom that would be a compelling reason to have a gastroscopy is food getting stuck when swallowing. In younger people this can be a sign of a type of food allergy; in older people cancer needs to ruled out if this symptom develops. Persistent or frequent reflux symptoms (e.g. heartburn), might be a reason to have a gastroscopy, particularly in older males where reflux can cause Barrett’s oesophagus. Persistent upper abdominal pain, particularly if there is associated vomiting would be another important reason for a gastroscopy.
