This the simplest and safest procedure of the bariatric surgeries. The weight loss is lower than the other surgeries, however. Also, individuals with gastric banding are more likely to regain weight in the long run.
There are currently three primary weight loss (or bariatric) surgeries being performed across the United States. They are Roux-en-Y gastric bypass, adjustable gastric banding and sleeve gastrectomy.
To be eligible for bariatric surgery, you must be between 16 and 70 years of age (with some exceptions) and morbidly obese (weighing at least 100 pounds over your ideal body weight and having a BMI of 40).
