Does a breast reduction change the nipple (areola really) size?

I have really large breast. I would say I probably average a 42DD, but I've never been measured (we can't afford things like that) and wear cheap bras that just don't hold up to breast this size. I am finally having them reduced. I am hoping that the areola area is going to be reduced too, but is something I forgot to ask. I know I can ask right before, and that is fine, but was hoping to see if it is typical.
