I am in China, been eating alot of noodles and not much good food. For about four weeks now I feel the urge for a bowell movement like five-six times a day. The stool is always runny and different colours. Sometimes it is black, sometimes it is light brown etc... but it is coming out stranger than what I am used to. I feel I can't go out because I always have my bowells playing up on me, to the point that I feel I may poop myself. Is it a bad diet (Definately different than what I was eating back home) Or an irritation to the different food I never ate back home? Thanks.
