Roux-en-Y gastric bypass (RYGB) surgery is the only treatment for morbid obesity that conveys substantial and sustained weight loss and long-term remission of obesity-related comorbidities, whereas lifestyle interventions have failed to reduce cardiovascular event rates in obese patients with type 2 diabetes.
For individuals with morbid obesity (BMI >40 or >35 with comorbidities), lifestyle interventions alone are insufficient for sustained weight loss and cardiovascular risk reduction. Bariatric surgery, specifically Roux-en-Y gastric bypass, is identified as the only treatment providing substantial, sustained weight loss and remission of comorbidities.
Currently, bariatric surgery is the only treatment for morbid obesity conveying a substantial and sustained weight loss and long-term remission of obesity-related comorbidities... Lifestyle intervention was not able to reduce the rate of cardiovascular events in obese patients with type 2 diabetes (16), but mortality might be reduced by bariatric surgery (11, 17).
