When to see a doctor
If you're an adult, see your doctor if:

- You have severe abdominal or rectal pain
- You have bloody or black stools
- You have a temperature of more than 102 F (39 C)
In children, particularly young children, diarrhea can quickly lead to dehydration. Call your doctor if your child's diarrhea doesn't improve within 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
