an upper GI might be needed to see if it slipped i had to have one because i was getting very hard stabbing pains in my chest when i tried to eat. but it turns out with all my regurgitation the area around my band was swollen then Dr left me empty for just under 6 months (not fun) i gained 30 of the 60 i lost and now I have 2cc's back in it and has helped a little but I am still not loosing but not plowing thru food like i was. it is so discouraging to not be like the people in the commercial, but i have to try again. (grrrr) good luck
