Seattle How does liposuction surgery work? Abigail V.

Hi Abi, thank you for your question. Liposuction involves removing fat from certain parts of the body to create a more streamlined shape.  There are two layers of subcutaneous fat: deep and superficial. During a liposuction procedure the doctor makes a tiny incision and inserts a hollow, stainless-steel tube called a  cannula into the deep fat layer.  The doctor pushes and pulls the tube through the fat layer. As the cannula moves, it breaks up fat cells, and a vacuum pump or syringe removes the fat with suction.  Liposuction is most often used for cosmetic purposes, to give a smoother shape to areas such as the thighs, abdomen, buttocks, hips, thighs, calves, arms or back — areas that haven’t responded to diet and exercise. It’s important to note that liposuction is not a weight-loss technique; it is merely a  reshaping technique. Only diet and exercise can result in real weight loss.
