This is a procedure where a thin, flexible tube called an endoscope is used to look inside the esophagus, stomach and first part of the small intestine.

When is a gastroscopy performed?

It is generally used to:

  • Investigate problems in patients who have difficulty swallowing (dysphagia) or persistent abdominal pain
  • Diagnose conditions such as stomach ulcers or gastro-esophageal reflux disease (GERD).
  • Treat certain conditions like bleeding ulcers, a blockage in the esophagus, non-cancerous growths (polyps) or small cancerous tumours.

How does the procedure work?

The endoscope is placed at the back of the mouth, and patients are asked to swallow the first part of the tube, which is guided down the esophagus and into the stomach.

Does it hurt?

The procedure should not be painful, although patients may experience mild levels of discomfort at times. A local anaesthetic spray is usually used to numb the throat; however, patients can also choose a sedative if they prefer.

How long does it take?

The procedure usually takes less than 15 minutes, although certain gastroscopies might take slightly longer.
