It is a better surgery then bypass as far as safety and long term complications are concerned, but it is only a temporary help in losing weight. More then half of my clients over the years have had weight loss surgeries. With sleeve you will lose some of the weight, but you will still have to deal with the exact same issues you have now and less then 5% keep it off. They regain it all within 3 years. You have to ask yourself if it is worth it. Maybe it is, but it is major surgery and the size of your stomach is not the problem. Your body chemistry and your metabolic disease is the problem. Those can be corrected without surgery
