Liposuction is a procedure that removes subcutaneous fat from the body through tiny skin punctures using negative pressure in order to sculpt and beautify the body shape. Liposuction is suitable for body shape defects caused by limited fat deposits (e.g., in the face-chin area, abdomen, iliac waist, and outer buttocks, etc.); it is also remarkably effective in improving limb bloat caused by fat abundance. Even if the patient continues to gain weight after the surgery, there will be no more localized protrusion affecting the body surface contour. In moderately to severely obese patients, large amounts of subcutaneous fat can significantly reduce the body’s need for insulin, thereby delaying the onset of diabetes or helping to control it. Since the procedure only reduces the number of fat cells and does not affect the metabolic activity of the rest of the fat cells, there is no rebound or fluctuation in weight, which is inevitable with other weight loss methods. Liposuction can also be used for the treatment of conditions such as limb lymphomas, lipomas, gynecomastia, gynecomastia, and armpit odor. However, in cases of skeletal or muscular body dysmorphia (e.g., muscular lower limbs and flabby abdominal muscles), liposuction alone can only achieve limited results and must be combined with other surgical procedures to correct the problem. After subcutaneous fat removal, most of the local skin can be retracted and flattened. A light diet, plenty of fluids and light activity for a few days after surgery are beneficial. Compression bandages should be applied to the surgical site after surgery.
