Diarrhea: Causes, Symptoms, and Treatment Guide

What Is Diarrhea?

Diarrhea is the passage of loose, watery stools occurring more frequently than normal. It affects all ages.

Common Causes

• Infections (viral, bacterial, parasitic)
• Food poisoning
• Medication side effects
• Food intolerances
• Certain medical conditions

Course and Complications

Most cases are self-limited, resolving in a few days. However, severe diarrhea can cause dehydration and electrolyte imbalances, which may be serious.

When to See a Doctor

Seek medical attention for severe diarrhea, signs of dehydration (dry mouth, decreased urination, dizziness), blood in stool, high fever, or persistent symptoms beyond a few days.
