The Functional Gut Clinic (FGC) is the UK’s first dedicated, independent Gastro-Intestinal (GI) Physiology service. Our core interest is to use state of the art technology to try and understand how your gut is functioning and to identify what is causing your troublesome symptoms.

The information that we gather helps you and your Doctor identify the exact problem and in turn this helps to develop a targeted therapeutic strategy based on the best available science and evidence. We can also arrange consultations with expert Physicians, Surgeons, Dieticians and Bowel re-training nurses to provide a truly joined up service.

The Functional Gut Clinic is the only UKAS / IQIPS accredited GI Physiology service in the UK (Watch: Exclusive video interview with Philippa Bassett – UKAS) guaranteeing that the service we offer is of the highest standard and constantly improving. We are inspected on an annual basis and all of our clinical staff are fully accredited GI Physiologists or GI Clinical Scientists.
