Banish soft drinks from school vending machines.Cut down on Happy Meals. Load school lunches with fruits and vegetables. Pull the plug on the television and shove kids outdoors. Those are some of the weapons that schools, doctors and parents wield to prevent overweight kids from packing on more pounds.

But there’s another possibility: Surgically implant an inflatable silicone band around the top of the stomach to restrict food intake. That way, people eat smaller meals.Banding works for many adults. NowAllergan In
C、, a maker of the band, is asking the Food andDrugAdministration to approve its device for morbidly obese adolescents as young as 14.
You may or may not find this hard to stomach. We suspect your response will depend on your view of the causes of obesity, teen and otherwise. If you think losing weight is only a matter of will power, then you probably will figure this is another stab at a quick-fix that can’t work for long.But here’s why we can’t dismiss it.Chicago is a national epicenter for childhood obesity. From toddlers to teens,Chicago’s children far exceed national averages for obesity.An obese teen faces a lifetime of increased health risks.
The band surgery wouldn’t be for the girl who wants to shed 25 pounds to fit into a dancing party dress. This would be for the morbidly obese—adolescents 100 pounds or more overweight. The surgery is safe and effective for adults. In limited trials, it has helped obese teens.A、2010 study in the Journal of theAmerican MedicalAssociation found banding surgery to be far more effective than diet and exercise programs in helping teens shed significant poundage. Of 25 patients who got the surgery, 21 lost more than half their excess weight.By contrast, only three of 25 teens on a supervised dieting and exercise program lost that much weight.
The prospect of such surgery on a teen should give pause to parents and doctors.But let’s remember that this is envisioned as a last resort for teens who are 100 pounds or more overweight.Before they’re cleared for surgery, kids would have to show they diligently tried other weight loss methods. That they could stabilize their weight in preparation for surgery.And that they’re ready to follow through with psychological counseling and other after-surgery programs.
Parents and kids need to know: There is no quick, pain-free way around diet and exercise as a weight control. Pills, gastric surgery and other shortcuts may help some for a while.But even surgery likely won’t be effective for long if you don’t change the way you think about food and about controlling portions. Yes, we share concerns that once doctors start ratcheting up the numbers of these surgeries, they won’t stop at the small numbers of extremely overweight teens.But that’s for doctors and parents to monitor. The FDA、should allow the band to be marketed for adolescents, to give them a chance at a normal, healthy life.

[A] it has proved to be more effective in reducing weight.
[B]Chicago has an excessive number of obese children.
