The most common cause of diarrhea is a mild viral infection that
resolves on its own within a few days, usually known as the
"stomach flu". Two other common causes of diarrhea is from food
poisoning and traveler's diarrhea. They occur from eating food or
drinking water contaminated with organisms like bacteria and
parasites. Medications can also cause diarrhea, especially
antibiotics, laxatives containing magnesium, and chemotherapy for
cancer treatment.
