A new technique that involves folding the stomach into pleats is being tested as a potentially less risky form of weight-loss surgery.
It involves no incisions, the entire procedure can be done via a tube passed down the throat and the patient can go home the same day.
Weight-loss surgery, also called bariatric surgery, is available on the NHS to those who are morbidly obese with a body mass index (BMI) of over 40 — or to those who have a BMI of 35 to 40, but whose weight is causing a serious, obesity-related health complaint, such as type 2 diabetes.
The new surgery does not require any incisions to be made and involves folding the stomach into pleats, shrinking it and preventing it expanding to accommodate food
Thousands already have the surgery each year and, recently, the National Institute of Health and Care Excellence proposed that those newly diagnosed with type 2 diabetes who have a BMI of 30 or above should be considered for it, too.
