Liposuction is a surgical procedure that uses a suction technique to remove fat from specific areas of the body, such as the abdomen, hips, thighs, buttocks, arms or neck. Liposuction also shapes (contours) these areas. To be a candidate for liposuction, you must be in good health without conditions that could complicate surgery — such as restricted blood flow, coronary artery disease, diabetes or a weak immune system.
