Diarrhea is characterized by loose, watery stools occurring more frequently than usual. It is often caused by viral or bacterial infections, food poisoning, medications, or digestive disorders. Symptoms can include abdominal cramps, urgency to have a bowel movement, nausea, and dehydration due to fluid loss. Treatment focuses on addressing the underlying cause and managing symptoms. This may include staying hydrated with water or electrolyte solutions, modifying diet to include bland foods like rice and bananas, and avoiding dairy, caffeine, and fatty foods. In some cases, over-the-counter medications or antibiotics may be prescribed to alleviate symptoms and promote recovery.
