bariatric surgery

Experts now say the procedure is the most effective treatment for severe childhood obesity, which affects a growing number of kids. But stigma and insurers often stand in the way.

Earlier studies suggested that most people put the pounds back on, but a large study that followed people for a decade after bariatric surgery found that the vast majority avoided gaining weight.

Bariatric surgery has a good track record in combating the health risks of obesity. But new health exchanges in Mississippi and other Southern states won't pay for it, even though those states have some of the nation's highest rates of obesity.
