Liposuction is a contouring tool and not a means to weight loss. It is used for shaping problem areas which have been resistant to diet and exercise. Even when approaching the high volume limits for the procedure a patient should not expect to lose much more than 11 lbs.It is difficult to make a prediction regarding losing inches around the waist. That being said, 5 inches is a fairly lofty goal to achieve through liposuction alone (which only addresses subcutaneous fat and does nothing for excess skin, muscle laxity or intra-abdominal fat).I often recommend that patients focus on a shape rather than a sterile number like a volume or a measurement, as these goals are very difficult to achieve and can often lead to disappointment.As always, discuss your concerns with a board certified plastic surgeon (ABPS).
