I need reduction surgery, but I am 30 lbs overweight.?

I have been given conflicting advice from different surgeons. One Doctor tells me to lose weight, the other one states it does not matter. Last year, I went on Atkins and lost all of my weight and my size did not change. Although I have recently regained the weight, still my size is the same. My neck, shoulders and back are constantly hurting, and I have to sleep in my bra to be comfortable. Is my weight really an issue when it comes to a reduction?
