The Welsh Health Specialised Services Committee (WHSSC) says there are 'strong reasons' for reviewing the criteria for weight-loss surgery eligibility.
It is thought 60,000 people in Wales have a body mass index of 40 or more. The healthy range is 18.5 - 24.9.

Bariatric surgery is a clinically and cost-effective specialised service for the treatment of morbid obesity.
There are strong reasons for revising the current access criteria and considering an increase in commissioning activity.
However, the majority of individuals seeking help to address problems of obesity will require non-surgical management, with bariatric surgery reserved for a small number of carefully selected cases.
Health regulator NICE recommends people with a BMI of 40 or more, or those with a BMI of 35-40 who also have another significant disease, should have access to bariatric surgery.
NICE also says bariatric surgery should be considered as a first-line treatment option for adults with a BMI of 50 plus.
