Recommendation | Most effective for patients with a BMI of 35-55 kg/m2 and those with a "sweet-tooth". Virtually all insurance companies will authorize this procedure. | Utilized for high risk or very heavy (BMI > 60 kg/m2) patients as a "first-stage" procedure. Very low complication rate due to quicker OR time and no intestinal bypass performed. Insurance companies will authorize this procedure in select patients. | Best for patients who enjoy participating in an exercise program and are more disciplined in following dietary restrictions. Many insurance companies will NOT authorize this procedure. |
