Professional profile

Dr Vinay Sehgal is a Consultant Gastroenterologist and Interventional Endoscopist at University College London Hospital. University College London Hospital is a centre of excellence with strong academic ties that enables its doctors to bring the latest treatments from the benchside to the bedside which is something Dr Sehgal passionately believes in for his patients.

Dr Sehgal qualified from The University of Liverpool in 2007 and completed his specialist training in Gastroenterology in the prestigous North East London rotation. During this time, he completed his PhD at University College London where he developed a novel tumour model of oesophageal cancer used in crucial mechanistic, imaging and pre-clinical studies. Dr Sehgal has been awareded numerous awards for his cutting edge and landmark research in this field.

Dr Sehgal regularly consults patients with a wide range of gastrointestinal symptoms and conditions but his areas of specialist expertise include:

  • Heartburn and acid reflux
    Causes, consequences and treatments (such as lifestyle changes, proton pump inhibitors, and hiatus hernia- directed therapies)
    Endoscopic diagnosis including BRAVO capsule insertion and endoscopic therapies for reflux including STRETTA
  • Barrett’s Oesophagus endoscopic therapy
    Endoscopic removal (EMR) and ablation (RFA, APC, Cryotherapy) for early neoplasia and cancer which would otherwise require major surgery
  • Major Upper Gastrointestinal Motility Disorders
    Investigation and endoscopic treatment of major motility disorders such as achalasia and OGJ-outflow obstruction with treatments such as botox or dilatation
  • Eosonophillic oesophagitis
    Endoscopic diagnosis including long-term dietary, medical and endoscopic therapies for this important condition
  • Oesophago-gastric cancer
    Endoscopic therapy including stenting, laser and cryotherapy
  • Colonoscopy
    Endoscopic treatment of pre-malignant colorectal lesions
    Diagnosis of chronic lower gastrointestinal inflammatory disorders including Crohn’s disease and Ulcerative Colitis
    Endoscopic treatment of colonic strictures that may otherwise require surgery
  • Trans-nasal endoscopy
    Transnasal endoscopy and minimally invasive imaging and monitoring in the upper GI tract
  • Small intestinal bacterial overgrowth
    Investigation and novel lifestyle modifications in combination with medical therapies
  • Functional gastrointestinal disorders
    Irritable bowel syndrome, cyclical vomiting syndrome, disorders of the gut-brain axis.


Dr Sehgal has a specialist interest in the early detection of pre-malignant lesions of the Upper GI tract with particular expertise in artificial intelligence-based classification systems to improve lesion recognition of Barrett’s-related neoplasia. He also has a specialist interest in advanced endoscopic therapy for benign and malignant disorders of the Upper GI tract. He is regularly invited to present at international meetings and has published numerous original manuscripts and reviews in this field.

Dr Sehgal recently led a team that introduced a non-invasive oesophageal tissue sampling device which was used to monitor patients with pre-malignant conditions of the oesophagus instead of endoscopy which was otherwise postponed due the COVID-19 pandemic. UCLH was the first centre in the world to adopt this technology with other centres following its lead and ultimately helping to improve the care we offer to such patients.

Dr Sehgal has a keen interest in endoscopy training and is a member of faculty at the British Society of Gastroenterology and Endoscopy Training Committee for The Royal College of Physicians. He is also actively involved in numerous live endoscopy and hands-training courses at UCLH.

Dr Sehgal has a keen interest in research and supervises a research team who collect important information into endoscopic techniques and procedures he carries out to ultimately improve and streamline the care that we give to our patients. His research is focused on exisiting and novel endoscopic imaging technologies to help detect and treatment early cancer of the gastrointestinal tract including the use of artificial intelligence.

His other interests include the development of minimally invasive endoscopic techniques to treat early cancers of the upper gastrointestinal tract for which he is actively involved in several national and international clinical studies in this field.
