If you take liposuction to lose weight, you should follow the principle of "a few times". Less attraction, less trauma, quick recovery, less pain and no need for general anesthesia. On the contrary, large-scale liposuction surgery is traumatic and painful, and requires a lot of anesthetic drugs, which increases the risk of anesthesia accidents. In addition, liposuction in a large area is a labor-intensive work for plastic surgeons, and it is easy to get tired. Even if there is no life safety problem, the accuracy of liposuction will be reduced due to fatigue, which will further affect the surgical effect.
