Gastric Bypass

High-Quality Gastric Bypass Surgery

 throughout South East England

Looking for gastric bypass surgery in South East England? Most commonly known as the Roux-en-Y gastric bypass, this weight-loss surgery procedure bypasses part of your digestive system, making your stomach smaller and reducing food intake at meal times. When your body absorbs less of the food you do eat, weight loss will become easier. Alternatively, we also offer gastric band and gastric sleeve surgeries. Get in touch with London Obesity Clinic today for more information.

About the Bypass Procedure

Performed as keyhole surgery, the gastric bypass procedure will be performed while you are under general anaesthesia. The procedure generally takes between 1 and 3 hours to complete. The average patient can expect to lose 60 to 70% of their extra weight after this surgery is complete. Although gastric bypass surgery can make it easier to lose weight, you must follow your diet plan to achieve the best results.

Cristin Casey

"Mr Agrawal was an absolutely fantastic surgeon, he was very supportive throughout the whole process."


Holly Grayson

"My experience with Mr Agrawal has been positive from start to finish, he’s absolutely lovely, he made me feel really at ease”



“After I had my children I put around 3 stone on and I tried everything to get it off, I’ve done all the diets everyone is familiar with, but the weight would come back on. The decision to have the operation was made 18 months after I was diagnosed with diabetes, I was not convinced I was going to have this operation, but it was one of the best decisions I have ever made
