Usually after a breast augmentation surgery, we do recommend that the patient sleep on their back for four to six weeks after surgery. It will be okay to sleep on the side after the first week, but what we don't want is the compression directly on the implant, which will force it towards the scar. So we could have an incision opening, so an open wound, or we can have a widening of the scar if we start putting pressure on that breast a little bit too early. And also, we could also have bleeding. So I'll tell my patients, you can sleep on your back sometimes with the head a little bit elevated so all the swelling comes down as the patient is healing. It's nice to sleep with a light post surgical bra or a light sports bra to give that sense of security and also to also improve a little bit of the swelling. But really sleeping on your stomach, I would say only after six weeks of surgery.
