Every day or two or more, with varying intervals, I'm seeing yellow objects in my stools. They look like yellow beans on the outside, feel rather gelatinous, and have a very white substance inside. My gastroenterologist says he has no idea what this is. Otherwise, sometimes I experience no other symptoms, but today, when I passed two unusually large "beans," my digestion is very upset and I have acute diarrhea. I'd very much appreciate any thoughts you have on this.
