I had my band fitted in september 2007 and lost about four and a half stone. I've gained about 3 stone back due to not working with the band and my thyroid being under treated ( I was on 125mcgr of thyroxine for a couple of years, I'm now on 200 mcgr) I have now started to lose weight again (13lbs in 4 weeks)by healthy eating, but with no help from the band. I have recently had 2 fills but still have no restriction. I'm worried that my band has slipped, can anyone give any advice please?
