Your doctor might recommend a Gastroscopy examination if you present with certain symptoms including nausea, vomiting, difficulty swallowing, heartburn, upper abdominal pain that does not go away unexplained weight loss and bloating.
Gastroscopy is also used as a routine screening for people who have a history of ulcers or polyps, to screen for stomach cancer and to check for abnormal findings detected on previous CT-Scan or X-Ray tests.
Gastroscopy can be used to treat certain conditions such as to remove a foreign body that has been swallowed by accident such as a fishbone. It can also be used to stop bleeding from ulcers, and cut out polyps or small stomach tumours.
