The best time to schedule tummy tuck is when you feel confident in your decision to undergo the procedure and the plastic surgeon you have selected. You should also have a stable weight (close to your ideal weight). Women who wish to restore their pre-baby body should wait at least six months following pregnancy. Because future weight gain can stretch out the skin and abdominal muscles, Dr. McAllister recommends that women wait to have tummy tuck until they are done having biological children.
