Liposuction, liposuction in English, liposuction and slimming in the medical books of plastic surgery center is a method of using instruments to penetrate into the subcutaneous fat layer through small incisions in the skin and absorb fat fragments, which is suitable for body shaping. To do liposuction, general anesthesia should be done first, and a wound of about 0.5 to 1.0 cm should be cut at the liposuction site, then the catheter should be directly inserted into the bottom of the fat accumulation, and then the excess fat should be pumped out by a vacuum compressor. This surgical method is called "dry pumping". Another method is to inject water and drugs after anesthesia, so that the fat cells at the liposuction site swell up, and then insert a straw for liposuction. This method is called "wet liposuction". The average adult can bear 500 ml of blood loss. Therefore, the traditional vacuum suction liposuction method only needs more than 4000ml； at a time; Ultrasonic liposuction does not exceed 10000 ml at a time, which is equivalent to 10 kg of fat, which belongs to the safe range. After liposuction, "fattening" cells will become fat again. Liposuction is still possible at this time, but the surgical site has become fibrotic, and the traditional liposuction effect is not good. Ultrasound liposuction is needed to be effective. Liposuction can be done countless times in a lifetime, but each time it is more technically difficult. Liposuction is one of the sculptural operations in plastic surgery. The principle is to suck out excess fat in a certain part of the body through negative pressure suction, so as to achieve the purpose of local rapid weight loss. The common parts of whole body liposuction are: face, double chin, neck, shoulders, limbs, hands and feet, upper and lower abdomen, side waist, upper buttocks, hip reduction and hip lifting.

Whole body liposuction should follow the principle of "small amount and multiple times". Less attraction, less trauma, quick recovery, less pain and no need for general anesthesia. On the contrary, large-scale liposuction surgery is traumatic, painful and slow to recover, 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 job 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. Generally speaking, no more than 4 servings at a time.

Experts will communicate with beauty seekers in detail before liposuction to lose weight, and design a reasonable surgical plan according to the beauty seekers' own situation. The equipment used in the operation is advanced, and the redundant fat is sucked out layer by layer by scanning, which will not produce uneven phenomenon. And more than 80% of the fat can be sucked out by one suction, which solves the pain caused by the long operation time of beauty seekers. The liposuction effect after operation is natural, with smooth lines and perfect curves. Liposuction is a physical method to remove excess fat cells around the navel. The growth of human cells is basically completed before 18 years old, and then fat cells generally no longer divide and grow. Therefore, it is very good for people after 18 to lose weight through liposuction. The most suitable age for liposuction and weight loss is 18 to 55 years old.
