Basically, if you have stretch marks and loose skin of your abdomen, you're typically a candidate for a tummy tuck instead of liposuction. The success of liposuction alone depends on having good quality skin in the area being treated,i.e. no stretch marks with good skin tone.
You may also some underlying weakness of your abdominal wall from pregnancy, aging or weight fluctuations throughout your life. This is best treated with a tummy tuck.
To augment your buttock area, you may be a candidate for liposuction followed by fat transfer to the buttock area to provide a fuller buttock , and to reshape the entire gluteal/lower back region.
Please consult with a board certifield plastic surgeon to find out which procedure is best for you.
Best wishes.
