What is Gastroscopy?

Gastroscopy is an investigation of the oesophagus and stomach from the mouth through to the start of the small intestine. This uses a tiny camera mounted at the end of a thin, flexible tube. It makes detection of conditions associated with stomach cancer much easier, such as inflammation and ulcers, as well as bacteria that increase the risk of stomach cancer.

Should I go for Gastroscopy?

A gastroscopy is recommended if you have any of the following symptoms:

  • Pain in the upper abdomen
  • Recurring heartburn
  • Recurring vomiting
  • Any other discomfort thought to be coming from the upper gut
  • You are above 40 years of age with a family history of cancer/stomach ailments.

Why is a regular Gastroscopy important?

It is important because early cancer has no symptoms or minimal discomfort. Early detection of ulcers and
cancer increases the chances of a full recovery. Prevention is always better than cure.
