The negative pressure determines the speed of liposuction. The greater the negative pressure, the faster the suction, but the greater the harm to the human body. Therefore, normal hospitals usually only use negative 1 atmospheric pressure, while in some informal institutions, in order to shorten the operation time and increase the pressure, it is easy to cause nerve damage to operators.

2, leading to skin relaxation

Skin relaxation after liposuction is an inevitable phenomenon. But for surgeons under the age of 40, the skin itself is very elastic and can slowly adjust and repair itself. With the increase of age, or obese people, the elasticity of skin decreases.

3, cause other diseases of the human body

People with weak constitution or poor visceral tolerance, because there is no obvious disease, if there is not enough communication before liposuction, or the doctor is negligent for a while, it is easy to cause other diseases. For example, the heart is not able to bear enough, and surgery may lead to poor blood supply, which may lead to shock or even death in severe cases.

4. The human body is numb.

The main nerves of the human body are in muscles, and the fat is mainly peripheral blood vessels and nerves. After liposuction, because the peripheral nerves are destroyed, the human body will be numb, and it will generally recover in about half a year. But don't think liposuction is absolutely safe. Liposuction must be within the body's tolerance. The more you smoke, the higher the risk. Generally, the amount of liposuction at a time is 2000-5000ml, and those who are weak or older should be controlled at around 3500ml.

5. Body exudates

Liposuction can not only cause local swelling, but also cause exudation, which is an inevitable short-term hazard. Liposuction is a traumatic operation, which will cause damage to small blood vessels and capillaries, leading to the exudation of swollen liquid and blood, which will stop within 24 hours.
