I've been reading quite a few posts where people are embarrassed and ashamed of telling co-workers and even family of their choice to having WLS. I really don't get it. I'm still pre-op (6 months diet, etc) and I couldn't wait to tell everyone I know (and their cousins) that I'm about to have WLS. In fact, one of the first people that I told to was my supervisor, and he is like 100% supportive. I believe because he is aware of my plans, he is being very accomodating to my pre-op doctor appointments and whatever is related to the surgery.
Very few people at work made negative comments about my decision, mostly saying that I'm "too small" to go for such radical procedure. To those, I just gave my PCP recommendation for WLS as a main reason, and my morbidly obese BMI.
Hiding the surgery is to a degree silly, like celebrities that swear never having plastic surgery. Won't it be obvious when you loose a bunch of weight (and keep it off) in a very short time?
