At the Mommy Makeover Institute of Hawaii, we do 9-15 procedures per week, and I have performed over 20,000 procedures (separate surgeries) in my career. I have never concerned myself with whether a patient was having her period or not on the day of surgery, and I have not seen any increased bleeding or other problems related to the proximity of one's menstrual period with surgery.From a technical point of view, we recommend our patients place a tampon in their vagina before surgery, the nurse removes the tampon at the end of surgery, and replaces it with a pad. This prevents embarrassing leakage, and the removal of the tampon at the end of surgery decreases the chance of the well documented complications associated with forgotten tampons left in after surgery. Each patient has to make her decision in consultation with her Board Certified plastic surgeon with reference as to what to do if one's period falls on the day of surgery. Personally, I see no problem technically or medically.
