Hi.Jordan. apparently, gastroparesis can be caused by Hypochlrhydria (low stomach acid) this would make sense to me as if you have ever been at the kitchen sink and smelled rotton food that has been trapped in the pipe, it smells loike someome has passed gas? could this be the bacteria that is feeding on the undigested food. maybe this is whats going on with us? just clutching at straws but kinda makes sense to me. any thoughts?
