Diarrhea is a common gastrointestinal condition characterized by loose, watery stools that occur more frequently than usual. It can be caused by various factors, including viral or bacterial infections, foodborne illnesses, certain medications, and underlying medical conditions. The primary symptom of diarrhea is an increased frequency of bowel movements, often accompanied by abdominal cramps, dehydration, and a sense of urgency. While most cases of diarrhea are acute and resolve on their own within a few days, persistent or severe episodes may require medical attention. Maintaining hydration is crucial in managing diarrhea, as fluid loss is a common concern.
