Bariatric surgery is the most effective treatment for morbid obesity, providing substantial long-term mortality reduction and remission of type 2 diabetes (T2DM) compared to non-surgical management.
For individuals with severe obesity (BMI ≥40 or ≥35 with comorbidities) who have not succeeded with lifestyle changes, bariatric surgery is the most effective medical intervention for long-term survival and diabetes remission. It is not a quick fix but a lifelong commitment requiring strict adherence to nutritional supplementation and medical monitoring to prevent deficiencies and manage metabolic health.
Bariatric surgery has proven to be the most effective mode of treatment of the morbidly obese patients, with recent long-term studies providing evidence of a substantial reduction of mortality in bariatric surgery patients as well as decreased risk of developing new health-related co-morbidities...
