Hi, I am an 18 year old female who sufferes from constant yellow diarrhea, burping and nausea. i have taken mutliple pregnancy tests to rule that out. Also, i feel like i always have to go, but when i sit down only a little comes out then i have to go about 15 minutes later. i am also experiencing alot of stress, and wake up almost every morning feeling nauseous. when i would make myself throw up to stop feeling sick, it was nothing but yellow bile. :-(
