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.

Dr Ahmed is extremely personable and easy to talk to, which immediately puts you at ease as a patient. He creates an environment where you feel comfortable discussing any concerns, no matter how minor or insignificant they may seem, without feeling rushed or judged. He is an excellent listener and takes a genuinely holistic approach, looking beyond the immediate issue and considering the wider factors that may be contributing to your health and wellbeing. I first saw Dr Ahmed several years ago, and that consultation left a very positive impression on me. When I recently needed medical advice again, he was the first consultant I wanted to see, which is why I specifically requested an appointment with him this time around. I remembered how approachable, thorough, and reassuring he had been, and that experience has remained consistent. From a clinical perspective, Dr Ahmed is meticulous and thoughtful. He does not rush to conclusions and instead ensures that all relevant information has been gathered before recommending next steps. He has been able to refer me to clinicians and specialists whom he trusts to provide accurate assessments and diagnostic results, which is incredibly reassuring as a patient. You get the sense that he wants to be certain of the facts before advising on a treatment pathway, which inspires a great deal of confidence. I have also been impressed by the responsiveness of both Dr Ahmed and his PA. Queries are dealt with promptly, appointments are arranged efficiently, and reports or letters are provided in a timely manner. This level of communication a...

I have now visited Dr Ahmad twice for different issues, once in 2024 and recently in October 2026. Every time, Dr Ahmad puts particular rigour into issuing the right diagnosis. During the intake, he always really listened to me and took my concerns seriously (after I was previously dismissed by an NHS GP). He also puts a lot of effort into doing the right type of tests without sending the patient through endless assessments. The whole process from initial consultation to test to follow up is really fast and efficient.

I had an excellent experience with Dr. Omer Ahmad, from the initial consultation through to the procedure itself. He was highly professional while also being friendly and approachable, which made the whole experience very comfortable. He explained everything clearly, took the time to describe what to expect at each stage, and was happy to answer any questions I had. His knowledge and expertise were immediately apparent and gave me a great deal of confidence that I was in very capable hands throughout the process. Overall, I was extremely impressed with the level of care and professionalism. Excellent in every aspect, and I would have no hesitation in recommending him.

During the past two visits seeing Doctor Ahmed, he has been very warm and supportive taking the time to listen patiently to everything I’ve had to say. During my most recent visit, Dr Ahmed was very professional and thoughtful throughout the procedure. He has been very understanding taking the time to explain it all easing my procedure. As a skilled professional, there were no issues during this procedure and I left feeling more confident.

One of a kind! I saw Dr Ahmad a few times now and every time get greeted with a big smile, which would immediately put anyone at ease. Apart from being extremely knowledgable and laser-focused of providing the best possible care, Dr Ahmad is extremely empathetic listener and communicator. On top of that, his office is extremely efficient and very on top of things. I would wholeheartedly recommend Dr Ahmad.

I have known and been under the care of Dr. Omer Ahmad for quite some time now and I can honestly say that his medical knowledge, professionalism, compassion and dedication to his patients are truly exceptional. Throughout the time I have been seeing him, I have always experienced the same level of care and attention. He is extremely knowledgeable and thorough, but what I value most is the way he genuinely cares about his patients. He treats people with kindness, respect and compassion, and always takes the time to listen and explain things properly. Recently, I had an MRI scan of my liver, which was naturally quite worrying for me. Speaking with Dr. Omer about the scan and hearing his professional and well-informed explanation was incredibly valuable to me. He took the time to explain the findings clearly, approach everything in a scientific and balanced way, and most importantly, reassure me when I was feeling anxious. His calm and caring approach made a real difference to me. I truly believe that doctors like Dr. Omer Ahmad are rare. He is not only highly knowledgeable and professional in his field, but also a genuinely caring and conscientious doctor who always puts his patients’ wellbeing first. I am very grateful for the care and attention he has shown me, and I would wholeheartedly recommend him to anyone looking for an excellent and compassionate doctor.

This was my 2nd colonoscopy with Dr Omer and it gave me a lot of comfort that he was doing it. He is professional, efficient and communicates well. I was mildly sedated for the colonoscopy and so was able to observe the procedure. It felt like a well organised and supportive theatre environment and he kept me updated on what he was doing throughout.
