What is a Gastroscopy?
Gastroscopy (also called upper GI endoscopy or OGD) is a procedure that allows your doctor to examine the lining of your oesophagus (food pipe), stomach, and duodenum (first part of the small intestine) using a thin, flexible tube with a camera.
During the procedure, biopsies can be taken and certain treatments can be performed, such as stretching a narrowed oesophagus or removing polyps.
Why might I need a gastroscopy?
- Investigation of reflux, heartburn, or indigestion that has not responded to treatment
- Difficulty swallowing (dysphagia)
- Persistent nausea or vomiting
- Investigation of suspected coeliac disease
- Surveillance of Barrett's oesophagus
- Investigation of iron deficiency anaemia
- Upper abdominal pain
- Investigation of weight loss
The Procedure
Gastroscopy is performed under light sedation. The procedure typically takes 10 to 15 minutes. You will need to fast (no food or drink) for at least 6 hours before the procedure.
After Your Gastroscopy
Recovery from gastroscopy is usually very quick. You may have a mild sore throat for a day or two. As with colonoscopy, you will need someone to take you home and should not drive for 24 hours.
