About
Janusz Jankowski is a consultant gastroenterologist with more than four decades in gastroenterology, cancer prevention, nutrition, and clinical trials. His training spans Glasgow, London, Oxford, Dundee, and Cambridge, and his research profile is unusually deep for a Dubai clinic: the AspECT trial in The Lancet, later work on Barrett's surveillance, 447 ResearchGate-listed publications, and 30,000+ citations. At Biongevity, that background is most relevant for reflux, Barrett's esophagus, GI cancer prevention, fatty liver, and metabolic digestive risk.
What to Know
Signature approach
Jankowski brings a prevention-first gastroenterology lens. For reflux, Barrett's esophagus, family GI-cancer risk, obesity, or fatty-liver patterns, the visit is about understanding trajectory: what needs surveillance, what can be modified, and where chemoprevention, nutrition, endoscopy, or metabolic care should sit. He is especially useful when trial-level evidence needs to become practical GI risk planning.
What sets them apart
- AspECT trial leadership. His Barrett's esophagus chemoprevention work helped define how high-dose PPI and aspirin strategies are discussed for the right patients.
- Research depth. 447 listed publications, 30,000+ citations, major GI oncology textbook work, and $100M+ in grant history give him rare academic weight in a clinic setting.
- GI cancer prevention focus. Reflux, Barrett's, nutrition, obesity, fatty liver, and surveillance strategy all connect to a coherent prevention focus.
Before You Book
- Care focus. Reflux, Barrett's esophagus, GI cancer risk, fatty liver, or digestive prevention questions that benefit from a research-heavy specialist.
- Dubai consults. Patient visits are in person in Dubai, with additional academic and advisory roles outside the clinic.
- Availability may vary. He is also publicly listed with Clemenceau Medical Center Dubai, so confirm Biongevity appointment timing before planning around him.
