Liposuction and a tummy tuck seem like such similar procedures. How do you know which you need? First, it’s important to understand the differences. Liposuction is designed to remove only fat from a targeted area. A tummy tuck, on the other hand, removes fat and extra skin from around your waist and tightens your six-pack abs in order to narrow your waist. If you’re still unsure of which procedure would be best for you, try standing up and bending over at the waist. Pinch the skin on your tummy. If there’s a lot of skin to pinch, a tummy tuck is likely the best option for you.
