During a BBL, fat is liposuctioned from one area of the body and injected into the butt. If too much fat is packed into a single spot—more than blood vessels can support—it can die. That’s called fat necrosis, and it smells about as good as it sounds. “When there is more fat in an area than the blood supply allows, the fat will die through a smelly process,” Dr. Anderson told the Daily Mail. It’s a complication that can lead to infections, hospital stays, and in rare cases, sepsis.
Imagine if you love going down on your partner and the smell of rotten flesh is a few inches away.
