Most cases of acute diarrhea last a short time and a search for the cause may not be necessary. Avoid undercooked or raw seafood, buffet or picnic foods left out several hours and food served by street vendors. Wash hands frequently, especially after using the toilet. Your own observation of symptoms. Medical history and exam by a doctor.
Diarrhea is a symptom.
If possible, the underlying disorder should be treated. If cramps are present, place hot compresses, a hot-water bottle or an electric heating pad on the abdomen. Maintain fluid intake. Severe diarrhea may require urgent fluid and electrolyte replacement to correct dehydration. Follow package instructions.
