Very effective : Studies show comparable weight loss to the bypass but safer and less invasive.. Long term resolution of medical conditions is also comparable with a slight advantage to the bypass for resolution of diabetes after 5-8 years.

Sleeve gastrectomy : The sleeve gastrectomy is very effective and has a high success rate. Patients typically lose about 60-65% of their excess body weight by a year to year and a half. That means if you are 100lbs overweight, you would lose 60-65 lbs. If you are 200 lbs overweight, you would lose 120-130 lbs. This doesn't mean you lose the weight automatically. You have to eat the right foods and exercise as well.
