Conducting Gastric Bypass Surgeries in Ilford, Essex, and covering the whole of the South East

Gastric bypass surgery, most commonly the Roux-en-Y gastric bypass, is a weight-loss procedure that works by making your stomach smaller and bypassing part of your digestive system. This means that you won't be able to eat as much during meals, and your body will absorb less of the food you do eat. At London Obesity Clinic, in Ilford, Essex, this is just one of the weight-loss procedures that we specialise in throughout the South East. Others include gastric band and gastric sleeve surgeries.

Helping You to Lose Weight

The gastric bypass is performed as keyhole surgery, and you will be under general anaesthesia so that you sleep through the operation. It generally takes between one and three hours to complete. The average patient can expect to lose around 60% to 70% of their extra weight after this procedure. Although the gastric bypass surgery can make it a bit easier to lose weight, you will only achieve results if you stick to your diet plan.

Jane - Gastric Bypass

“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 familair 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.”
