Liposuction involves the removal of fat by small tubes, or cannulas, attached to a vacuum aspiration device. Only fat in the subcutaneous layers of the body are accessible for liposuction, but instead must resort to dieting and exercise for this visceral fat loss. Liposuction is not a substitute for proper diet and exercise. Although liposuction, per se, is not a reliable way of losing weight; it is a very reliable means of contouring.
Once the fat cells are removed, your net fat cell number is reduced permanently, thus making it theoretically more difficult for you to regain the fullness in the treated area. Liposuction is essentially a redistribution operation in that the fat in the areas treated is reduced in proportion to the rest of the body. We are frequently asked if the fat "goes somewhere else", or if one tends to put on weight in other areas of the body. One explanation for this perception may be that without a change in caloric intake, in the setting of stable or declining basal metabolic rate (which occurs as we age), it is predictable that fat would accumulate as a means of storing energy. If the depots of fat that were once present have been significantly reduced in capacity, then it follows that those fat depots remaining untreated may tend to accumulate more fat if energy intake exceeds energy expenditure.
It is therefore very important that patients considering liposuction understand the importance of diet and exercise in maintaining their weight, and realize that liposuction is not an alternative to a healthy lifestyle.
It remains that with any elective cosmetic surgery, it is very important for women considering this procedure to be given informed consent. This means that anyone considering having permanent implantation of a medical device is made aware not only of the risks of the operation itself, but also of the lifelong risks of having implants.
