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.
