Both laser liposuction and coolsculpting can be used in someone with diastasis. However, the contour improvement will only be related to the superficial or pinchable fat. There will be less flattening of the abdomen due to abdominal bulging; and there will be no effect postively or negatively to the diastasis. In general, if you can pinch it, you can get rid of it. In patients with significant diastasis, a tummy tuck may be preferable for optimizing results. It is important to have a consultation with a body contouring expert who is experienced in non-invasive and invasive techniques to get an accurate assessment of potential results. Patients with significant diastasis sometimes have hernias present and should be evaluated for this; coolsculpting should probably not be performed in a patient with a hernia present.
