My Dr checks everytime to see how much is in the band. It should be what was put in the last time. I had 3cc in my band when I went for the fill. He then added another half cc. When he did I felt a tightness at my port area. He felt it to because he said this one feels really tight. It felt different from all my previous fills. Well I went home and was on liquids then soft. Then I started on regular food and I felt wide open. So when I went back the next month I said this is not working I can't feel anything. He was joking as he got ready for the fill saying I will put more in and then you will be throughing up and mad at me. And then he stopped talking and said Oh you don't have anything in your band no wonder you are gripping. You may have a leak. He put 1.5cc back in and said come back in a month. Well I could tell there was something there again and when I went back I said I don't think I have a leak and he checked and it was all there. So he has been putting in more each month. I went yesterday and I am now at 3cc again. I don't know what happened when I lost that fill, maybe the needle slipped or something but it happened to me and set me back 4 months in fills which is a bummer. I wish my Dr did floro but he doesn't. He is not a band Dr only he does mostly RNY but is an excellent Dr and does not put bandsters down he just wants what is best for his patients.
