COVID-19 traceability should not be based on political accusations It is very important to further trace the origin of the virus

The risk of liposuction for weight loss is closely related to the standardization of surgical procedures. Under standardized procedures, the risk is controllable, but there are potential complications such as bleeding, infection, and fat embolism. Liposuction is an invasive surgery that requires negative pressure extraction of subcutaneous fat to achieve a shaping effect. If blood vessels are damaged during the operation, it may lead to local hematoma or excessive intraoperative blood loss, and timely hemostasis is necessary. Improper postoperative incision care may lead to bacterial infection, manifested as redness, swelling, heat pain, and even suppuration. Antibiotics such as cefaclor dispersible tablets and levofloxacin tablets should be used for control. The most serious risk is the entry of fat particles into the bloodstream, which can lead to pulmonary embolism. Clinically, sudden breathing difficulties and blurred consciousness can be seen, requiring emergency rescue. In special circumstances, the risk will significantly increase. Excessive liposuction may lead to uneven subcutaneous tissue or skin necrosis. Patients with combined cardiovascular and cerebrovascular diseases and coagulation dysfunction are more likely to experience circulatory fluctuations during surgery. Allergies to anesthetics may trigger shock reactions. Long term improper wearing of shapewear after surgery may affect lymphatic return and lead to chronic edema.

It is recommended to choose experienced doctors from formal medical institutions to perform preoperative tests such as coagulation function and electrocardiogram to evaluate tolerance. Strictly follow the doctor's advice to use antibiotics after surgery, wear medical compression shapewear for 3-6 months, and avoid vigorous exercise. Maintain a balanced diet and regular exercise in daily life to prevent compensatory hypertrophy of residual fat cells.
