Bariatric surgery is a safe, effective, and durable treatment for severe obesity in people with Type 2 Diabetes, leading to significant weight loss and high rates of diabetes remission, yet it remains significantly underutilized.

If you have severe obesity and Type 2 Diabetes, bariatric surgery is the most effective treatment for long-term weight loss and diabetes remission. It is recommended for those with a BMI over 35, or over 30 if your diabetes is recent. Despite being safe and effective, it is underused. Discuss with your specialist if you are a candidate, keeping in mind the need for lifelong vitamin supplementation and monitoring.
