I think you only get bloody stool if there is bleeding AFTER the stomach, because the stomach blood gets digested and doesnt appear in your poop. But i dont know that from experience. Im just making an educated poop guess.

Idk. It sounds like you are rationalizing your way out of a slow blood leak, when it could account for some of your dis-ease, no?

Again, idk. I hate to throw up. I really hate the idea of putting my face in a toilet. Just THAT will make me throw up. If i have a bad stomach upset, i prepare a small trash can lined with several plastic bags.

Might be why i never had kids.
