My biggest concern about WLS was that I viewed this as the last ditch effort for losing weight and having had a past of losing weight only to gain it all back again eventually was preventing me from making this decision for fear that I would be doing something as drastic as this and it was probably not going to work either. thankfully, I overcame that fear after listening to my surgeon at the info session explain all the health benefits of WLS and all the health detriments of remaining obese. I have to admit that now even 18 mos. post surgery I still am fearful of gaining back my weight.
