Taxpayers should be appalled by Medicare’s decision to pay for some types of bariatric surgery to treat obesity. Unlike many other conditions, obesity is frequently reversible without a surgeon’s intervention. Try eating less and walking more (“Medicare to cover surgery to treat obesity,” Money, Feb. 22).

Unfortunately, Americans have gotten away from such simple wisdom. And they’ve had plenty of help. Stomach-stapling doctors and makers of weight-loss drugs have spent years lobbying government to cover their products. In essence, they want to turn obesity into a recognized “disease” with taxpayer-funded “cures.” Perhaps they could call this new disease “couch-potato-itis.”

What’s the next step? Will Blue Cross be forced to buy me a treadmill?
