Weight-loss surgery is not for everyone. Usually candidates have tried
and failed repeated attempts to lose weight. Most are at least 100 pounds
overweight. To qualify for the Baylor Grapevine program, you must have
a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with
medical complications such as heart disease or diabetes due to obesity. BMI is the ratio of your height to weight.
