Most cases of diarrhea resolve without treatment. However, severe diarrhea can cause dehydration, which can be life-threatening if untreated. Dehydration is particularly dangerous in children, older adults and those with weakened immune systems.

Seek medical attention for your child if:

• Diarrhea doesn't improve after 24 hours
• 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 tongue 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 for yourself if:

• Your diarrhea lasts more than two days without improvement
• You become dehydrated — indicated 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)
