Bariatric surgery
Weight-loss surgery for people whose health is affected by obesity, with lifelong follow-up as part of the treatment.
Bariatric surgery changes the size or route of the digestive tract so that less food is needed to feel full, and in some procedures so that fewer calories are absorbed.
It is a tool rather than a cure. The operation changes what your stomach can hold; it does not change what you want to eat, how you respond to stress, or the habits built over years. Sustained results come from the combination of the surgery and the change that follows it, which is why every serious programme includes dietetic and psychological support rather than treating the operation as the end point.
These are major abdominal operations with real risks, including a small but genuine risk to life. Whether surgery is appropriate for you — and which procedure — is a decision for a qualified surgeon after reviewing your medical history, measurements and any obesity-related conditions. Nothing on this website can make that assessment, and no clinic should offer to make it from a form.
