Reasons for having a gastroscopy

A gastroscopy may be advised if you have symptoms such as:

  • Repeated (recurring) indigestion
  • Recurring heartburn.
  • Pains in the upper tummy (abdomen).
  • Repeatedly being sick (vomiting).
  • Difficulty swallowing.
  • Other symptoms thought to be coming from the upper gut.

The sorts of conditions which can be confirmed (or ruled out) include:

  • Inflammation of the oesophagus, called oesophagitis. The operator will see areas of redness on the lining of the oesophagus.
  • Stomach and duodenal ulcers. An ulcer looks like a small, red crater on the inside lining of the stomach or on the first part of the gut (small intestine) known as the duodenum.
  • Inflammation of the duodenum (duodenitis) and inflammation of the stomach (gastritis).
  • Stomach and oesophageal cancer.
  • Various other rare conditions.

Safety and Risks

Serious complications following a gastroscopy are rare, at less than one in 10,000 examinations. However, complications can occur and your doctor will explain these before your procedure.
