Diarrhea
Overview
Diarrhea is usually caused by a virus or, sometimes, contaminated food. Less frequently, it can be a sign of another disorder, such as inflammatory bowel disease or irritable bowel syndrome.
Symptoms
Symptoms include frequent, loose, watery stools and belly pain.
Treatments
Most cases clear on their own. Some infections may need antibiotics. Severe cases can cause enough dehydration to require IV fluids.
