Gastrointestinal tract and liver expert

A Gastroenterologist is a doctor with specialist training and experience in the investigation and management of symptoms and diseases of the gastrointestinal tract and liver.

In the UK this involves an average of 10 years of postgraduate training with additional time spent in research.

Gastroenterologists have a detailed understanding of the normal action (physiology) of the gastrointestinal organs as well as the diagnosis and management of common and important diseases of the gut.

Gastroenterologists also receive dedicated training in endoscopy (upper endoscopy, sigmoidoscopy, and colonoscopy). This specialized training includes detailed and intensive study of how and when to perform endoscopy, optimal methods to complete these tests safely and effectively, and the use of sedating medications to ensure the comfort and safety of patients. In the UK each consultants endoscopy practice is continuously reviewed for quality and safety.
