Liposuction is risky and may cause uneven skin, loose skin, numbness of nerves, infection of liposuction site, fat liquefaction and other hazards. 1. Uneven skin: Liposuction can only be operated locally at one time, and it is not good to control the amount, too much or too little liposuction locally will lead to uneven skin. 2. Loose skin: After liposuction, the loss of large amount of fat will make the skin lose its support, which will lead to loose skin. 3. Numbness of nerves: there are peripheral blood vessels and nerves in the fat, after liposuction, because the peripheral nerves are destroyed, the human body will usually have numbness, and in serious cases, it will cause damage to the nerves of the patients. 4. Liposuction site infection: the medical equipment used in liposuction will destroy the integrity of the skin, and poor sterilization or poor resistance will make the liposuction site infected with local symptoms such as redness, swelling and pain, and in severe cases, it can cause septicemia. 5. Fat liquefaction: Liposuction will stimulate and damage the local adipose tissue, causing abnormal fat metabolism and poor healing ability, thus fat liquefaction occurs. In addition, it may also cause fat embolism and local hard nodules. When you need liposuction, you should go to a regular hospital for examination and evaluation, and have liposuction under the doctor’s advice.
