Gastroscopy

Gastroscopy, or upper endoscopy, is a diagnostic procedure used to examine the oesophagus, stomach, and duodenum using a thin, flexible tube equipped with a camera. It is commonly performed to evaluate symptoms such as upper abdominal pain, reflux, nausea, or difficulty swallowing.

The procedure is usually done under local throat anaesthetic and intravenous sedation. The gastroscope is passed through the mouth and advanced through the upper digestive tract, providing real-time visualisation. Biopsies or therapeutic interventions may be performed if needed.

Gastroscopy is safe and well-tolerated. Temporary throat discomfort is common. Rare risks include bleeding or perforation, especially when tissue samples are taken.

Patients are required to fast for at least 6 hours before the procedure. Full preparation and post-procedure advice is provided.
