Swelling fluid can not only relieve pain, but also separate fat cells from other tissues, reducing pain and bleeding during aspiration. There are not many side effects on human body, but it should be noted that excessive liposuction will increase two major risks: anesthesia and fat embolism.

If you smoke 1000ml of fat, you need to inject 1000ml of swelling fluid, while if you smoke 2000ml of fat, you may need to inject 2000ml of swelling fluid. The main components of swelling fluid are lidocaine and adrenaline. Most lidocaine will be absorbed by human body, but excessive injection of adrenaline may cause chills in limbs, elevated blood pressure, palpitations and other adverse reactions.

When fat cells are extracted in a large area, the probability of destroying small blood vessels increases, and the probability of fat embolism caused by broken fat cells entering blood vessels also increases. Therefore, the general doctor will not advise you to pump too much fat at a time.
