Liposuction, also known as liposuction for weight loss and body sculpting, is a procedure to improve the body’s appearance by removing the accumulated subcutaneous fat through a small skin incision by negative pressure suction or other related physicochemical means. The development of liposuction is advancing rapidly along the direction of continuous technical innovation, improved surgical results, and significantly reduced trauma and complications, and more and more beauty seekers are accepting this surgery, which has become one of the most popular cosmetic surgery procedures. Generally, the amount of fat extracted in one operation is about 3000 ml, and the maximum amount cannot exceed 5000 ml. Therefore, if the amount of fat is too much, multiple liposuction treatments will be needed, but the exact number of times you need to do liposuction depends on your own situation. Liposuction requires the doctor’s full attention during the surgery, which is also physically demanding. In order to keep the surgeon in good condition and make the surgery safer, a liposuction procedure should be limited to 2-3 hours. Therefore, for those who need liposuction in multiple areas or a large amount of liposuction, it is usually necessary to complete the surgery in several sessions.
