Could not wearing your surgical or sports bra 2 days after surgery cause a hematoma?

Many factors can cause a hematoma after breast augmentation.  However not wearing your bra is not one of them.  If the hematoma is going to occur, it will occur whether or not you are wearing your bra.

Hematomas are caused by excessive bleeding into the breast implant pocket after surgery.  Hematoma is a medical term which can be broken into two parts:  1) "heme" meaning blood; 2) "oma" meaning a swelling, in this case caused by blood.Your question would indicate that you wore the surgical bra for the first two days, and then apparently took it off.  Forty eight hours after surgery, it is very unlikely that the normally restricted post augmentation movements would lead to a collection of blood if a surgical bra was not worn.The short answer is that post surgical garments rarely, if ever, decrease the chance of a hematoma.
