According to the 1991 National Institute of Health criteria, bariatric surgery is offered to individuals with Body Mass Index (BMI) > 40, or individuals with BMI > 35 and obesity-related illnesses such as diabetes, obstructive sleep apnea, high blood pressure, joint disease, etc. To determine your BMI, use the BMI calculator.
- 100 lbs or more over ideal body weight or
- Have a Body Mass Index (BMI) of 40 or greater or
- Have a BMI of 35 or greater with two or more obesity-related co-morbidities (medical problems) such as diabetes, obstructive sleep apnea, high blood pressure, joint disease, etc.
People who have not yet tried traditional weight loss techniques are usually not candidates for bariatric surgery. Usually, you have to have tried and failed to lose weight using traditional methods. While surgery is a proven weight loss tool, it should not be the first option.
