Dr. Clive Onnie


About Me

I qualified at The London Hospital Medical School in 1996 with a distinction in medicine and a first class honours degree in pharmacology. I subsequently worked in several world leading hospitals including St Mark’s and Guys and St Thomas’ Hospitals. I undertook a Masters in Medical Science at the Hammersmith hospital in 2001 and completed a PhD at King’s College, London in the genetics of inflammatory bowel disease where I was awarded a Digestive Diseases Foundation Research Fellowship.

I was appointed Consultant Physician and Gastroenterologist at the Whittington Hospital NHS Trust in 1997, as well as Honourary Senior Lecturer at the University College London Medical School. I also act as the medical adviser to the North London Chapter of the Crohn's and Colitis UK Organisation.

Clinical Practice

I see NHS and private patients with a wide range of common gastrointestinal problems including reflux (indigestion, heartburn), dyspepsia, abdominal pain, diarrhoea, constipation, rectal bleeding as well as for investigation of abnormal liver function tests.

Specialist Interests

My ongoing research interests are in the genetics of inflammatory bowel disease. My areas of expertise are in the management of inflammatory bowel disease and irritable bowel syndrome, utilising both conventional and alternative approaches, as well as diagnostic and therapeutic endoscopy.
