About Dr. Omer Ahmad

Dr Omer Ahmad is a highly acclaimed, multi-award-winning Consultant Gastroenterologist based at University College Hospital London (UCLH). He currently serves as the clinical co-lead for the North Central London Endoscopy Regional Network.

Nationally ranked 1st in the UK for entry into specialist training, Dr Ahmad has received several prestigious accolades, including the British Society of Gastroenterology’s Clinical and Translational Scientist of the Year Award and the National Endoscopy Rising Star Award.

His clinical expertise focuses on the early detection and treatment of pre-cancerous conditions within the upper and lower gastrointestinal (GI) tract. He is a specialist-accredited Colonoscopist for the National Bowel Cancer Screening Programme, a role that demands strict accreditation and performance auditing. Beyond advanced endoscopic procedures, his practice also covers a broad spectrum of gastrointestinal disorders, including gastro-oesophageal reflux disease (heartburn), bloating, and irritable bowel syndrome.

Dr Ahmad studied medicine at University College London, graduating with distinction in both clinical sciences and clinical practice, along with a First-Class Honours intercalated degree in Pharmacology. He received the A.J. Clark Prize for the best overall academic performance and was named to the prestigious Dean’s List.

He went on to complete an academic endoscopy fellowship and earned a PhD at UCL, where he developed pioneering artificial intelligence software for the early detection of gastrointestinal cancers, technology that is now used in clinical settings. He remains actively involved in leading-edge research at the Division of Surgery and Interventional Sciences and the Surgical Robot Vision Research Group at UCL.

We had a very positive experience with Dr Omar Ahmed. He was kind, professional, and took the time to listen to my daughter’s medical history and current symptoms without making us feel rushed. He explained everything clearly and gave us a sensible plan for the next steps. We left the appointment feeling reassured and with a much better understanding of what to do next. I would happily recommend Dr Ahmed to anyone looking for a caring and knowledgeable gastroenterologist.
