Does your poop be yellow

Yes. People with Gilbert's Syndrome don't process as many blood cells - or not as fast - and their waste tends to be pale brown or yellow from the lower quantity of discarded red blood cell matter. This is especially true if there is less matter in your intestines (i.e., on a diet - as I have noticed) to remove the excess blood cells. Very frightening until you determine what is causing it. Gilbert's is a totally benign thing that doesn't harm anyone, although when a person is sick they can turn yellowish as if jaundiced, but it is not jaundice."

Another cause of yellow waste is a giardia infection. Giardia are tiny Protozoan parasites that can invade the intestines and result in severe yellow diarrhea. It is a dangerous and contagious affliction that doctors are obligated to report to the Center for Disease Control.
