First, these people can't have liposuction.

1. Obese people with heart disease, hypertension, diabetes, liver and renal insufficiency and hemorrhagic diseases are not suitable for liposuction to lose weight.

2. Hyperendocrine or morbid obesity caused by a certain disease is not suitable for liposuction.

3. Children under eighteen are not perfect in physical development, so they should be treated with caution.

Commonly used methods include tumescent negative pressure liposuction, ultrasonic liposuction, electronic liposuction, laser liposuction and hydraulic liposuction.

1. tumescent negative pressure liposuction is less bleeding, easy to master, large suction, safe and reliable. It is one of the main liposuction methods at present. Mainly suitable for abdomen, thighs and other parts with high suction.

2. Ultrasonic liposuction is to suck out the fat with a negative pressure aspirator after ultrasonic emulsification. Its advantages are labor-saving, less bleeding and no serious complications, while its disadvantages are low efficiency, time-consuming and less aspiration.

3. Electronic liposuction uses electric energy to decompose liquefied fat, and then sucks it out with a negative pressure aspirator. Its advantages are less bleeding, quick recovery of skin elasticity and neat appearance. The disadvantage is low efficiency.

4. Laser lipolysis is to use special laser energy to introduce fat cells into specific parts of adipose tissue through ultra-fine optical fibers, and then take them out of the body with real-time low suction through thin tubes, or choose not to take them out and be absorbed by the body through metabolism. It has a good effect on facial liposuction.
