What are the long term effects of liposuction?

Once the fat is suctioned from the
abdominal area, it is gone for good. The one, finicky thing about the abdomen
is that the skin may not retract and flatten out depending on the elastic
quality of the skin. You need to fully exam this with your plastic surgeon at the time of the consult.

Injury to internal abdominal organs from liposuction is more of an acute
medical emergency, which can be lethal . . .

There's really nothing appreciably significant long-term with liposuction. I will qualify this by saying some of the laser and ultrasonically assisted liposuction create cutaneous scarring can be significant. It should have no effect on the internal organs ever.
