Each time I went for a doctor appt, I have a few pounds so they said I did not need a fill. I was told that with the AP lapband, there is some saline in the band when they put the band in place. I lost 18 to 20 from 5/28 to 7/01. Then 5 more pounds before a visit, then later about 5 pounds more. That next visit, since I lost 5 pounds since the last visit, the doctor didn't think I needed a fill
