Management of Obesity
The nonsurgical treatment of severe obesity like diet ,exercise and drugs is a life-long struggle with own weight. While no one disputes the ability of morbidly obese patients to lose weight  for significant weight loss but the challenge is to maintain weight loss in the long term .

Bariatric surgery (weight loss surgery) is the only treatment modality that produces significant, sustained, long-term weight loss in patients with severe obesity . The National Institutes of Health,USA consensus conference in 1991 stated unequivocally that  surgery is the only approach that provides consistent, permanent weight loss for morbidly obese patients.
