Yes, my preop surgeons visit, I asked that question of weight gain w the sleeve bc I'd seen a lady who had gbs n gained it all bck n then some...he said yes, w any1 of the surgeries mentioned, u can gain it all nd more bck IF U CHOOSE to make the SAME BAD CHOICES AS PREOP, the surgeries are all tools, aides, to help us succeed, NOT MAKE US SUCCEED, it is still going to b up to the patient to make the tool work w u, not for you:) hope that helps nd makes sense to u. If u think its going to stop you from making bad choices, u shud rethink ur decision, the only thing that can do that is wiring ur mouth shut, then ud prolly die:/ start learning all u need to know about how to use the new tool, sleeve, prior to getting it. I mean, u can't know how to build a house just bc som1 handed u a hammer, it won't build itself, right? And u can't build a better more healthier you wo knowing how to work w ur sleeve. So gl to us all:))
