Liposuction is generally referred to as liposuction, and common hazards include wound infection, chronic pain, skin laxity, and postoperative embolization. Liposuction is the use of instruments to absorb localized fat for body contouring purposes. Usually the effect of liposuction is relatively ideal, but some people may have wound infection, localized radiating pain and skin laxity after the surgery, which mainly jeopardize the health, reduce the quality of life and local aesthetics, and should be taken seriously. In some people, liposuction may induce pulmonary embolism and cerebral embolism because the fat particles enter the organs, which may be directly life-threatening. Some people may also experience localized edema, uneven or necrotic skin, hyperpigmentation and other hazards after surgery. Liposuction is contraindicated for special groups such as morbid obesity, severe skin laxity and too little subcutaneous fat tissue. It is recommended that those who have the need for liposuction should consult a regular hospital and undergo surgery after the doctor’s evaluation and exclusion of contraindications. After the surgery, the patient should pay attention to strengthen the skin care and closely monitor his/her condition, and if he/she suffers from any discomfort, he/she should consult a doctor in time.
