I had the LAP-BAND® put on , on 8-2-08. I have been able to keep off 70 lbs. The past couple of months I have been sick and in a lot of pain. I had a x-ray done and it showed by band had slipped to the bottom of my stomach. I will need to have the band put back into place. Has this happened to anyone? What could be the cause. One of the side effects is reflex, which is not fun at all.
