I tell my breast reduction patients to sleep in any position they find most comfortable after their procedure. I don't think sleeping position affects the final outcome of a breast reduction procedure. Most women choose not to sleep on their stomach right after their procedure.Best of luck to you!
There are many different opinions regarding antibiotics. Some surgeons give none, some one dose at the time of the anaesthetic and some give oral antibiotics to take home. I would not be concerned. As long as everything is progressing well you do not need prophylactic antibiotics.
Surgeons are not restricted to removing a certain gm amount of breast tissue by insurance companies. They often have a minimum amount that must be removed. I would request a second consultation to discuss how much will be removed and the size you want to be. Better to ask all...
