I wonder what it costs the ins companies to treat diabetes, heart disease, and a multitude of other medical problems? What's cheaper - WLS or a heart attack? The National Inst of Health says a tiny percentage of people effectively lose weight thru dieting. Insurance actuaries are no dummies. They know it's cheaper to allow WLS then shell out a lot more to treat weight-related diseases. That's why they're easing up on requirements. A single payer (govt) health care system would likely offer WLS. Medicare is a govt single payer system for folks 65 and older and it allows WLS. In fact it set the guidelines for WLS requirements that insurance companies follow (BMI, etc.) So, I think the govt and the insurance companies agree it's a cost-effective solution to obesity. (IMHO)
