2.5 weeks post fat transfer to breast, how long until I can sleep on my side?

Your fat cells are fragile until about 3 months post op so we tell our patients to avoid sleeping on the side for that length of time.  Many buy the big pregnancy pillows and those seem to work really well.

Every surgeon has different post op instructions for his or her patients, I recommend you consult this with your PS.Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA

Just as is the case with fat transfer to the buttocks, you want to avoid direct pressure to your breasts (such as sleeping on your stomach) for anywhere from 2-4 weeks after surgery. If you still have swelling and/or pain, you won't want to do this anyway, but sleeping on your side should not pose a problem even 1 week out from surgery.
