Dr Devinder Bansi

Consultant Gastroenterologist /
Medical Director Weight Doctors UK


Endoscopic weight loss procedures mark a revolutionary stride in our battle against obesity. As a Consultant Gastroenterologist, I’ve witnessed their transformative power:  minimal invasiveness, swift recovery and unparalleled patient comfort. They are indeed the future of obesity intervention.


Career & Education

Dr Devinder Bansi, Weight Doctors UK Medical Director and our UK Lead Clinician, is one of London’s leading experts in endoscopic weight loss procedures. He is actively involved in a number of UK and international studies investigating methods of weight loss using endoscopy as an alternative to surgery. 


Dr Bansi qualified from the University of Southampton Medical School in 1988. He completed several junior medical posts and knew early on that he wanted to work in gastroenterology. In 1993, Dr Bansi was appointed as a Research Fellow in Gastroenterology at the prestigious and internationally renowned John Radcliffe Hospital in Oxford. He completed his MD thesis in this field and published several peer-reviewed research papers in leading journals.   


After completing his training in Gastroenterology and General Medicine, Dr Bansi was appointed as a Consultant Gastroenterologist and Honorary Senior Lecturer in Medicine at the prestigious Hammersmith Hospital NHS Trust and the Royal Postgraduate Medical School (now part of Imperial College).  


Dr Bansi became one of the Trust’s most senior and leading interventional endoscopists. He has a particular passion for minimally invasive, endoscopic treatments for weight loss. In addition to ESG and Gastric Balloon treatment he has established the largest series of patients undergoing stoma revision (TORE) for weight regain post gastric bypass surgery.

Experience really matters

Undergoing weight loss treatment is a big decision, often patients have considered it for years before taking the plunge. 

For a long time patients were presented only with surgical options for obesity. Whilst these options can be good, they are also invasive. Weight Doctors® recognised early on that a large potion of weight loss patients are generally healthy with a BMI lower than 50. A minimally invasive, yet powerful procedure suits these patients perfectly. 

Weight Doctors® were amongst the first European specialists to provide Endoscopic treatment for weight loss and have grown to be the largest with centres across UK, the Netherlands, South Africa, Germany and beyond. Not only that, Endoscopic treatment is our speciality and passion. 

Working with International experts such as Dr Devinder Bansi, Professor Karl Miller and Professor Thomas Hoelting soon saw Weight Doctors® at the cutting edge of endoscopic treatment and performing cases in high volume. 

Now ESG sits alongside traditional surgical weight loss methods, is approved for use within the NHS and attracts around 10'000 patients each year. 

With all this said, ESG is an intricate procedure only to be performed by experts who carry out the procedure routinely and with an excellent clinical team. At Weight Doctors®, patients can be confident of this expert team, alongside excellent clinical facilities and industry leading aftercare.
