Diarrhea is the frequent passage of unformed, watery, sometimes urgent bowel movements.
It is a common symptom of the stomach flu or gastroeteritis. You may also experience a crampy pain throughout the abdomen, especially before each stool. Unless recommended by a doctor, DO NOT use medications that slow the peristalsis of the bowel such as Lomotil or Immodium as they may slow elimination of toxins or organisms. Black or bloody diarrhea may signal bleeding from the stomach or intestines. Severe abdominal pain.
