Liposuction is process in which stubborn fat deposits are removed from specific body areas, such as the stomach, thighs, chest and hips. Liposuction works best for patients who have stubborn fat deposits that they are not able to remove through diet and exercise alone. Fat is removed by inserting small thin tubes under the fat layer, which are connected to a large vacuum pump or suction syringe. Fluid is injected into the areas from which fat is to be removed; this helps to prevent blood loss. Liposuction can be performed on several areas of the body at once.
