This is a common misperception. Following your Laser Liposuction procedure, should you experience weight gain or loss, it will tend to be proportionately distributed over your entire body. Once you have fat removed, it is gone and, assuming a healthy lifestyle of proper diet and exercise, it will not return or migrate. However, because fat is necessary to a healthy body, some essential fat layers in any given site remain untreated. If you do gain a significant amount of weight, the remaining fatty tissue will expand. Normal aging changes can also be expected.
