Whether you have conventional liposuction or SmartLipo or other laser-assisted liposuction, you should see some reduction in volume by six weeks. Even if you are swollen, and many people are, there usually is significant volume reduction. Depending on the area(s) you had done, you can ask the surgeon how many ccs of fat were removed and that may give some clue. Sometimes if too many areas are treated, the surgeon is limited based on how much anesthetic is used and not enough liposuction is done. If this was the case for you, then if you need to have a second procedure (I usually suggest waiting for six months) then you might limit the number of areas done per surgery. Also remember, that liposuction is not a replacement for diet and exercise, so you have to be diligent about watching your calories after surgery. You should be eating less than before surgery to maintain a lower volume of fat on your body.
