I have had IBS for a few years with normal symptoms and mostly normal bowel movements. Today something out of the ordinary happened and I made the mistake of googling it. (bad idea!) My stool was a normal brown color (shape, size, exc) but at the end was white. It almost reminded me of when a dog eats and passes a kleenex. Sorry for the gross description! I have looked up white stool and mostly came back with liver related responses. But, the stool was normal brown, just had a white chunk at the end. There was also a bit of mucous that passed. Is this IBS related or do I have something else going on??
