During tummy tuck surgery, the skin is lifted so it can be pulled down and the excess discarded. The process of lifting the skin off the muscles involves cutting through numerous blood vessels, both those coming up from the muscle as well as blood vessels that are cut with the long incisionNormally the skin survives with the remaining blood supply from the chest and the sides. However, both nicotine and cocaine cause blood vessels to squeeze way down so that instead of being like a large drinking straw that's served with boba tea, they shrink down tight like those little red cocktail straws.The healing tissue needs oxygen to survive, and the new scars need oxygen to heal. Blood vessels that are squeezed like tiny straws allow many fewer red blood cells to reach the wound. Red blood cells carry oxygen. So nicotine and cocaine starve the tissues of oxygen.What are the three main risks?1. Tissue loss2. Separation of the incisions3. InfectionBecause you didn't expose your body to nicotine or cocaine until two weeks after surgery, I am hoping your wounds may have healed enough to survive without complications. You need to see your plastic surgeon and describe what happened so he/she can look for any problems. Bring in your garment or binder so he/she can make sure it doesn't create any pressure points and that it's not too tight, since too much pressure can cause skin breakdown.Good luck!
