What is Gastroenterology?
Gastroenterology is the branch of medicine that looks at diseases of the oesophagus (gullet), stomach, small and large intestines (bowel), liver, gallbladder and pancreas. 

A gastroenterologist is a doctor specialising in the management of diseases of the gastrointestinal tract and liver.

Referral Expectations

Your GP will refer you to our service if they are concerned that you have problems that require a specialist gastroenterology consultation regarding the diagnosis or treatment of your condition. You may also be referred directly to the Gastroenterology Department for a specific procedure without a prior clinic appointment.

Waiting times for clinics range from 0-6 months depending on the urgency, which is assessed from the letter we receive from your GP.

Initial clinic appointments will take 40 minutes and any follow up appointment will be 20 minutes.  A history of your symptoms will be taken as well as a review of any medications you are on (please bring these with you).  You will then be examined and depending on your complaints, this could be a rectal examination.  From here you may be referred for more tests and you will be notified of this during the appointment and in writing.


8:00 AM to 4:00 PM.
