Total body liposuction is a common cosmetic surgery procedure that uses liposuction needles under anesthesia to suck out fat accumulated in the thighs, abdomen, arms and other areas. In general, regular, professional doctors do not recommend liposuction of multiple parts at once, and full-body liposuction needs to be completed in several sessions, and the operation should not take too long. The amount of liposuction in one surgery needs to be decided according to individual circumstances. In general, the amount of liposuction in one operation is controlled at about 3000ml, and for those with more fat accumulation, 4000ml is also possible, and 5000ml is the safe limit. However, if a candidate chooses an unqualified institution to perform the surgery, it may lead to the following side effects: 1. infection: irregular aseptic operation or prolonged surgery during the surgery can lead to bacterial infection; 2. uneven liposuction surface: shallow liposuction level or repeated liposuction of the same part may lead to uneven liposuction, thus causing uneven liposuction surface; 3. subcutaneous blood leakage: The liposuction process may damage the subcutaneous blood vessels, which may cause slight bruising and swelling under the skin if it is a small vessel, and may lead to a large amount of hematoma under the skin if it is a large vessel; 4. Fat embolism: The liposuction process may lead to fat mistakenly entering the larger blood vessels in the body, and the fat may reach other organs in the body with blood circulation, causing blockage of some small blood vessels, thus leading to fat embolism. In summary, candidates should choose a regular hospital and be operated by a doctor with enough experience to obtain good surgical results while minimizing surgical risks.
