I am no Dr. But it is generally related to the anesthesia, if you feel you are having more problems call your Dr.
I knew that after my gb surgery that their was something wrong and I kept calling and complaining and finaally they did aan x-ray and found some surgical equiptment in me like I believe it was surgiical scissors or something like that, it was a long time ago., so they went back in and got rid of them, after that, I was ok except I still cannot eat anything spicy or fatty.
Good luck!
