Bariatric surgery may be an option for adults who have a:

  • Body Mass Index (BMI) of 40 or more, OR
  • BMI of 35 or more with a serious health problem linked to obesity, such as type 2 diabetes, heart disease, or sleep apnea
  • BMI of 30 or more with a serious health problem linked to obesity, for the gastric band only.

Obesity is defined as having a body mass index (BMI) of 30 or more. BMI is a measure of your weight in relation to your height. Class 1 obesity means a BMI of 30 to 35, Class 2 obesity is a BMI of 35 to 40, and Class 3 obesity is a BMI of 40 or more. Classes 2 and 3, also known as severe obesity, are often hard to treat with diet and exercise alone.

Bariatric surgery is an operation that helps you lose weight by making changes to your digestive system.

Laparoscopic Bariatric Surgery

Laparoscopic Bariatric Surgery

Some types of bariatric surgeries make your stomach smaller, allowing you to eat and drink less at one time and making you feel full sooner. Other bariatric surgeries also change your small intestine—the part of your body that absorbs calories and nutrients from foods and beverages.

Bariatric surgery may be an option if you have severe obesity and have not been able to lose weight or keep from gaining back any weight you lost using other methods such as lifestyle treatment or medications. Bariatric surgery also may be an option if you have serious health problems, such as type 2 diabetes or sleep apnea, related to obesity. Bariatric surgery can improve many of the medical conditions linked to obesity, especially type 2 diabetes.* Having surgery to lose weight is a serious decision. If you are thinking about having bariatric surgery, you should know what’s involved. Your answers to the following questions may help you decide if surgery is an option for you:

  • Have you been unable to lose weight or keep it off using nonsurgical methods such as lifestyle changes or drug treatment?
  • Do you understand what the operation involves and its risks and benefits?
  • Do you understand how your eating and physical activity patterns will need to change after you have surgery?
  • Can you commit to following lifelong healthy eating and physical activity habits, medical follow-up, and the need to take extra vitamins and minerals?
