I have lost 4 pounds in 17 months. I ahd a great weightloss but now I ahve just stopped. I ahve had to be filled and un filled a few times inbetween. I am sticking to my plan and doing everything as I have done in the past. Is it possible for the band to fail and not show any signs of it doing so? I ahve had numerious bariaum U GI's done and all it shows is being too tight at times. Is is possible for a bandster to ahve another band put in or to have the gastric bypass surgery. My surgical date was Sept. 2007 I have lost about 97 pounds since then.
