Gastroscopy is a medical procedure used to visualise the inside of the upper gastrointestinal tract. This includes the oesophagus, stomach and duodenum. It is a relatively safe and well-tolerated procedure that can be performed in an outpatient setting.

There are a number of reasons why a healthcare practitioner may order a gastroscopy. One of the most common is to investigate the cause of gastrointestinal bleeding. This may be either fresh blood or old blood that has been partially digested and appears as black stools. Other indications for gastroscopy include Suspected ulcers, gastro-oesophageal reflux disease (GERD),Inflammatory bowel disease (IBD), and cancer screening.

The procedure is performed by passing a flexible endoscope through the mouth and into the stomach. The endoscope is a thin, tube-like instrument that is equipped with a light and a camera. This allows the practitioner to get a clear view of the inside of the gastrointestinal tract. Gastroscopy is generally a safe procedure, but there is a small risk of complications such as perforation, bleeding and infection.
