Liposuction requires surgery with suctioning to remove fat. The ways in which this is performed currently is much less invasive than in the past, but does have some downtime and recovery -- whether with a laser, manual, ultrasound or other methods such as power-assisted. Non-invasive fat loss does work, with coolsculpting (zeltiq) and ultrasound (liposonix) showing the best results in studies and having the most long-term patient treatments. however, each procedure only gives a small amount of body contouring or weight loss as compared to what can be done with true liposuction/lipocontouring. you will get weight loss with surgical suctioning, however it is not as significant as one would think and exercise and diet are necessary to keep the results long-term. i wish you the best of luck, Dr. Emer.
