Well, I definitely cannot give you any professional advice. Please let me say that up front, just what I have observed. I have seen wonderful sucess stories going in and out our doors each day though. I have attended a couple of support group sessions here at the office and will be attending one tonight. It seems everyone varies quite a bit on when they lose though. Some patients lose quite a bit at first, others don't. Some patients really start losing after their first fill and others it may take a few. The loss seems to happen for everyone but at different times. I would have to say at this practice I have seen a lot of patients lose six to eight pounds every six weeks during the first year as an average. Hope that helps a little. I would not hesitate to call your surgeon's office with any questions you may have about what to expect during this post op stage. Do you have a support group? Honestly, that is where I have learned the most on what to expect. Leslie
