After years of technical improvement, the safety of liposuction with “swelling technology” and “negative pressure suction” as the core has been recognized and widely used. However, liposuction is a surgical procedure, and there are risks associated with any surgery. The most serious complication of liposuction is fat embolism, which can be detected and treated early by experienced physicians. The most serious complication of liposuction in recent years is fat embolism, which can be detected and treated early by experienced physicians. Therefore, the more you pump, the better; the more you pump, the greater the chance of an accident. It is recommended that the amount of liposuction be limited to 3,000 ml, and for heavier people, it can be relaxed to 4,000 ml, but never more than 5,000 ml. Liposuction is mainly for localized fat accumulation, especially in the abdomen, waist, buttocks, outer thighs and other areas where subcutaneous fat tends to accumulate and is difficult to be lost through exercise. The use of liposuction in these areas can result in a significant improvement in body line. Therefore, liposuction is usually classified as “body contouring” rather than “weight loss”. In adults, the number of fat cells is constant and changes in fat and weight are due to changes in cell volume. Only liposuction can reduce the number of fat cells, so the results are permanent. Some people may feel slightly fatter after liposuction for a period of time than when they first had liposuction. This is not a rebound, but rather a result of improper diet causing the remaining fat to become larger and fatter. In fact, as long as you do not overeat and exercise properly, you will be able to maintain a nice figure.
