Liposuction is a body contouring procedure in plastic and cosmetic surgery, in which fat is sucked out from the deep part of the body by means of negative pressure suction. With the update of surgical instruments in recent years, there are now a variety of procedures such as hydrodynamic liposuction, laser lipolysis, and radiofrequency lipolysis. The more the instruments and equipment are updated, the less painful the patient is and the safer the surgery is. Fundamentally, liposuction is a surgery that needs to be handled very carefully by the surgeon and carries certain surgical risks. Liposuction involves inserting liposuction needles into the abdomen and thighs to draw out the fat. The wound is very small and no blood can be seen on the outside, but it is more traumatic to the body and requires a full body checkup. Only in very good physical condition can a candidate do liposuction surgery, which may cause bleeding and infection during and after surgery, and in serious cases may cause fat embolism and even endanger life. Therefore, it is recommended that the majority of candidates must choose a regular hospital and have the surgery performed by a skilled surgeon, and must have good communication with the surgeon before the surgery to understand the indications for the surgery as well as the safety during the surgery. In addition, patients with cardiovascular disease, diabetes and advanced age are not recommended to undergo this surgery.
