Gastroscopy — also known as upper endoscopy — involves using a thin flexible tube (endoscope) to examine the upper digestive tract. The tube is inserted into the mouth and travels down the food pipe (oesophagus), then into the stomach and first part of the small intestine (duodenum), to view these areas.

Is a gastroscopy painful?

The doctor carrying out the procedure will place the endoscope in the back of your mouth and ask you to swallow the first part of the tube. It will then be guided down your oesophagus and into your stomach. The procedure shouldn't be painful, but it may be unpleasant or uncomfortable at times.

How long does it take to recover from a gastroscopy?

Most people are able to resume normal activities after 24 hours. The operator writes a report and sends it to the doctor who requested the gastroscopy. The result from any sample (biopsy) may take a few days, which can delay the report being sent.
