Bariatric and Metabolic Surgery

Weight loss surgery, also called bariatric or metabolic surgery, is sometimes used as a treatment for people who are very obese.
It can lead to significant weight loss and help improve many obesity-related conditions, such as type 2 diabetes or high blood pressure.
But it's a major operation and in most cases should only be considered after trying to lose weight through a healthy diet and exercise.
Weight loss surgery is available if:
-
you have a body mass index (BMI) of 40 or more, or a BMI between 35 and 40 and an obesity-related condition that might improve if you lost weight (such as type 2 diabetes or high blood pressure)
-
you've tried all other weight loss methods, such as dieting and exercise, but have struggled to lose weight or keep it off
-
you agree to long-term follow-up after surgery – such as making healthy lifestyle changes and attending regular check-ups
Speak to a GP if you think weight loss surgery may be an option for you.
There are several types of weight loss surgery.
The most common types are:
-
gastric band – a band is placed around your stomach, so you do not need to eat as much to feel full
-
gastric bypass – the top part of your stomach is joined to the small intestine, so you feel fuller sooner and do not absorb as many calories from food
-
sleeve gastrectomy – some of your stomach is removed, so you cannot eat as much as you could before and you'll feel full sooner
-
All these operations can lead to significant weight loss within a few years, but each has advantages and disadvantages.
