Bariatric Surgery for Type 2 Diabetes in Adults

If you have uncontrolled type 2 diabetes and obesity, weight loss surgery—also known as bariatric surgery—may be an option. Even moderate weight loss—a loss of approximately 5 percent of excess weight—in people who are obese can help manage diabetes and prevent complications. More significant weight loss may be able to help reverse the condition.

NYU Langone doctors offer several types of surgery, such as gastric bypass surgery, that either limit the amount of food your stomach can hold or decrease the amount of food that is absorbed by the digestive system. On average, people who have bariatric surgery lose approximately half of excess weight within two years. 

People with type 2 diabetes who have bariatric surgery are strongly encouraged to 
adopt and maintain healthy eating and exercise habits. This commitment to a healthy lifestyle enhances the effectiveness of bariatric surgery and reduces the risk of complications. 

Your NYU Langone doctor provides you with specific instructions on how much you can eat after surgery. Our registered dietitians offer guidance on how to achieve optimal weight loss. 

You and your doctor take into account your lifestyle and goals, as well as the benefits and risks of surgery, before deciding whether it is a good option for you.
