Gastric bypass operations in the UK are costing the NHS over £85 million a year.

(In 2011-12 there have been 1,316 gastric band insertions and 124 gastric band removals performed for obesity under the NHS, and there have been 5,407 gastric bypass procedures performed under the NHS for obesity. The figures, provided by the Health and Social Care Information Centre, show an increase of
530% in 6 years.)

A gastric band is an inflatable band that sits around the top of the stomach. Inflation of the band narrows the stomach, limiting it’s capacity to take food and increasing the feeling of fullness. This, combined with lifestyle changes, leads to weight loss.
