Diabetics who undergo weight-loss surgery have been found to need fewer medications and have lower health-care costs.

Around 75 percent of obese patients with Type 2 diabetes were able to stop insulin and other blood-sugar controlling drugs within six months of bariatric surgery, according to a study by researchers at the Johns Hopkins University School of Medicine published in the Archives of Surgery.

Bariatric surgery reduces stomach capacity by stapling off the stomach and creating a very small pouch.

The study suggests insurance should pick up the $30,000 hospital stay since the surgery seems to be the only way to provide a sustainable reversal of both obesity and Type 2 diabetes. Around 220,000 morbidly obese people in the U.S. had bariatric surgery last year, according to the American Society for Metabolic & Bariatric Surgery.

Obesity costs Americans around $150 billion a year, according to the Centers for Disease Control and Prevention.
