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.

My experience with Dr. Ahmad was exceptional. I felt heard and understood from moment zero. I was given very detailed explanations and treated with an extreme amount of care. Dr. Ahmad even sent me the result of a scan on Saturday because he knew I was stressed about it. The procedure was super easy to do due to the doctor’s and his team support throughout. I don’t have a single complain. Would recommend this doctor and team to anyone.

Dr Ahmad and his team were fantastic. I submitted an enquiry form online and within 24 hours had a response from his team organising a same week appointment. Dr Ahmad was incredibly knowledgeable, reassuring and kind. I had my endonoscopy in under 24 hours from my first consultation and all ran smoothly thanks to him and the team.

I am very grateful for his expertise, availability and reassurance. I feel relieved to have seen a clinician of such high calibre. Very grateful to Dr Ahmad and his team.

After dealing with my symptoms for nearly a year, seeing Dr Omer Ahmad has been one of the best decisions I've made. From my very first appointment, I felt genuinely heard and listened to. After so long searching for answers, being able to fully explain my symptoms and have them taken seriously was incredibly reassuring. Dr Ahmad took the time to listen carefully, explain the possible causes of my symptoms, and clearly walk me through the next steps. He never made me feel rushed and answered all of my questions in a way that put me at ease. For the first time in a long while, I feel optimistic about getting answers and moving forward with treatment. I am very grateful for the care, professionalism, and compassion he has shown throughout the process.
