For people who are very obese and have loose skin, simple liposuction can't achieve good shaping effect. For this kind of people, liposuction and abdominal plastic surgery must be combined, that is, on the basis of liposuction, part of the waist and abdomen skin is removed, and the surgical trauma will be greater than that of liposuction alone, but the plastic effect is better, so whether liposuction on the waist and abdomen has side effects is also related to the choice of surgery.
