Bariatric surgery (Roux-en-Y gastric bypass or laparoscopic adjustable gastric banding) combined with low-level lifestyle intervention achieves significantly higher rates of Type 2 Diabetes (T2DM) remission and greater weight loss compared to intensive lifestyle intervention alone in obese adults with BMI 30-40.
For individuals with obesity (BMI 30-40) and Type 2 Diabetes, bariatric surgery (specifically Roux-en-Y gastric bypass or laparoscopic adjustable gastric banding) is significantly more effective than lifestyle changes alone in achieving diabetes remission and substantial weight loss. While lifestyle interventions are important, they rarely lead to remission on their own in this population. Surgery should be considered a viable and superior option for disease management, particularly for those who have not achieved remission through lifestyle changes.
Among obese participants with T2DM, bariatric surgery with 2 years of an adjunctive low-level lifestyle intervention resulted in more disease remission than did lifestyle intervention alone.
Why this rating
