Two babys, slow weight gain, whatever the cause, you just need some help flattening that stomach area. Maybe you just want to like what you see in the mirror again. A tummy tuck procedure can get rid of both fat and hanging skin. This is the difference between a tummy tuck and liposuction, that just gets rid of the fat. Liposuction also tightens the muscles, which has a profound effect on changing a loose stomach into a firm, tight abdomen.
