For me, the sleeve made sense over the RNY, because I was not severely obese (in fact, my insurance may not have covered it if I didn't have two other "co-morbidities" -that is, problems caused or made worse by being overweight that would be resolved or lessened by wt. loss) -I have hypertension (was on 3 meds) and arthritis in my knees. The sleeve was appealing to me because I can still take NSAID's (such as Advil, Motrin, etc.) later on if I need it, which you cannot with RNY. Also, it appealed to me that the normal anatomy was less disrupted this way -no bypass, and also much less dumping syndrome. I am just 7 days out, so we will see in 6-12 months if I made the right decision for me! I have lost almost 7 lbs in 7 days, so I think so far the weight loss couldn't be better! I have read (and have been told) that the weight loss for the sleeve is just about as good as the RNY, but a lot of it has to do with how much one exercise as the weight comes off, so I'm determined to do that too! The other very short-term difference is (at least where I had surgery) the RNY is a 36-hour stay, but the sleeve is about 48 hours, which isn't really that different. I didn't mind the second night in the hospital -I wouldn't have felt ready to go home yet anyway. I liked having the nurses and my surgeon around to make sure everything was OK and to ask questions about things if I needed to. I'm sure no matter which one you choose, it will be right for you and you will do well. The most important thing is to do as they tell you -everything is for a reason and will help you to recover better and faster. I agree that you should also ask your surgeon if he would recommend one over the other for you, given your individual needs. Good luck!!
