In general, for a person to be a candidate for surgery, all of the following must be met:
A BMI of 40 or more or a BMI of 35-39.9 with high-risk co-morbid condition such as high blood pressure, diabetes or sleep apnea with a current treatment regimen.
Because surgery is a very serious undertaking, generally, candidates must have tried non-surgical treatments such as dietary programs, behavioral modification, and exercise. Most insurances require a 6 month physician supervised diet (1 initial visit and 6 follow ups totaling 7 physical months).
There must be no medical or hormonal reason for the clinically severe obesity. These conditions are rare, but require treatment of the underlying medical problem.
The candidate must be fully informed about the surgery and what can be expected both as to weight loss and possible complications.
The candidate must demonstrate a willingness to accept the risks of surgery and to make dramatic lifelong changes in his/her lifestyle, dietary habits, exercise, and to commit to medical follow-up.
