Liposuction is a growing concern among beauty seekers. Although liposuction can reshape a more perfect body shape, it also has potential risks that must be a concern, mainly including the following: 1. Local unevenness: The most common complication of liposuction. Because during liposuction surgery, local swelling solution will be injected to suction out the fat cells, but it is sometimes difficult to evaluate the local flatness particularly carefully under the swelling situation, which is related to the doctor’s experience and also has a great relationship with the patient’s local skin laxity and fat expansion; 2. Local swelling: because the amount of liposuction surgery is usually large and the damage is relatively large, the recovery period of postoperative swelling may be longer; 3. Damage to blood vessels: nerves and surrounding tissues; 4. Fat embolism: a more serious hazard of liposuction surgery, but the chance of occurrence is small. Early postoperative activities can avoid fat embolism. It is recommended that patients should get out of bed on the same day after surgery to facilitate blood circulation in all parts of the body, and pay attention to the appropriate amount of liposuction, as there is a greater chance of embolism with excessive liposuction; and the configuration of swelling solution should be as reasonable as possible, which can effectively prevent fat embolism. Therefore, in the process of liposuction, patients should ask an experienced doctor to make a detailed risk assessment on the amount and location of liposuction before deciding on the scope and location of liposuction.
