Review of weight loss surgery for obese people in Wales

A review is examining if weight loss surgery should be offered to greater numbers of obese people in Wales.
Welsh ministers are awaiting a report into criteria deciding who is eligible for operations which could mean surgery is available for the less obese.
The review is also considering the cost to the NHS of changing guidelines.
One surgeon said Wales should eventually lower the threshold at which people qualify for NHS-funded surgery, as recommended by a health watchdog.
Radio Wales' Good Morning Wales presenter Peter Johnson spoke to Scott Caplin, a consultant surgeon at the Welsh Institute of Metabolic and Obesity Surgery at Morriston Hospital in Swansea.
