When to see a doctor
By Mayo Clinic staffMost cases of diarrhea clear on their own without treatment. However, diarrhea may cause a loss of significant amounts of water and salts. See your doctor if you experience any of the following.
Seek immediate medical attention
In children, particularly young children, diarrhea — especially if combined with either fever or vomiting or both — can sometimes lead to dehydration. Call your doctor if your child's diarrhea doesn't improve after 24 hours or if your baby:
- Hasn't had a wet diaper in three or more hours
- Has a fever of more than 102 F (39 C)
- Has bloody or black stools
- Has a dry mouth or cries without tears
- Is unusually sleepy, drowsy, unresponsive or irritable
- Has a sunken appearance to the abdomen, eyes or cheeks
- Has skin that doesn't flatten if pinched and released
Schedule a doctor's visit
In adults, diarrhea usually resolves on its own without any complications. See your doctor if:
- Your diarrhea persists beyond three days without any sign of improvement
- You become dehydrated — as evidenced by excessive thirst, dry mouth or skin, little or no urination, severe weakness, dizziness or lightheadedness, or dark-colored urine
- You have severe abdominal or rectal pain
- You have bloody or black stools
- You have a fever of more than 102 F (39 C)
