What happens during a gastroscopy?
A gastroscopy (examination of the stomach) can help confirm or rule out the presence of medical conditions like gastritis or peptic ulcers. In this procedure, a flexible, thin tube (called a gastroscope) is used to look at the inside of the food pipe, the stomach, and part of the duodenum (the first part of the intestine). At the end of the gastroscope, there's a small camera with a lamp on it. The images from this video camera are sent directly to a screen.
Gastroscopy may be done if you have the following:
- Chronic or recurring heartburn, nausea or vomiting
- Nausea over a long period of time
- Stomach pain
- Trouble swallowing
- Black-colored stool, which may be a sign of bleeding in the upper part of the digestive tract
- Weight loss for no apparent reason
- Suspected peptic ulcer
- Suspected cancer of the food pipe or stomach
- A check-up after stomach surgery
