Sleeping position after fat transfer to breasts?

Every surgeon has a different post op instructions for his or her patients, I recommend you consult this with your PS.

Dear M.Sch.,every plastic surgeon has his own postoperative protocol which he recommends to his patients. I would suggest you to discuss this with your plastic surgeon.Daniel Barrett, MD, MHA, MS

I ask my patients to avoid pressure of the area grafted for 3 months. I suggest sleeping on your back for that time, however, it is best to ask your surgeon what he/she prefers.

Many plastic surgeons will advise patients to avoid pressure to their breasts for several weeks after fat transfer.  Because each surgeon has his/her own preference and experience regarding positioning, activity, and garments after fat grafting, be sure to check with your own surgeon about what specifically you can and cannot do to achieve the best results.Hope this is helpful, and best of luck,Dr. Lim
