Overview
Diarrhea means passing loose or watery stools three or more times a day. Most cases are acute (lasting 1–2 days) and resolve on their own. But chronic diarrhea (lasting more than 4 weeks) needs medical evaluation. The biggest immediate risk is dehydration, especially in children and the elderly.

Self-Care Tips
Stay hydrated — drink oral rehydration solution (ORS) or clear fluids
Eat bland foods: rice, toast, bananas, boiled potatoes
Avoid dairy, fatty, and spicy foods until better
Wash hands thoroughly to prevent spread
Probiotics may help shorten duration
Avoid anti-diarrheal medication if you have fever or bloody stools
When to See a Doctor
See a doctor if diarrhea lasts more than 3 days, you have blood or mucus in stool, high fever, severe abdominal pain, signs of dehydration, or if it's a young child or elderly person.
