I'm 6 months post op a full Tummy Tuck with Lipo and bs. Will a lipo revision help my protruding stomach? (photos)

One would expect a flatter abdomen after and abdominoplasty. This might require re-tightening of the abdominal wall with or without liposuction it's impossible to tell without an examination.

If your muscle repair sutures become undone, liposuction will not be of any benefit.  You will need replacement of the muscle repair sutures to fix your problem.  Ideally your belly button would be redone at the same time.
