I had a leak in my balloon. I was going and going for refills and not feeling any restriction. Then I finally mentioned that I could eat a 6 inch Subway and my Dr took me serious. He filled me to a 10 (I have a 14 cc band) and by the time they did the test with the dye it was all gone. So mine was big. If you feel like you have one, tell your Dr. you want the florioskpy (?) test. That way they can also see where it is leaking from. The port, band, etc. I have many friends who have had this done and none of them needed to keep getting fills. I had to have my surgery redone. Good luck.
