Signs and symptoms associated with diarrhea may include:

  • Frequent, loose, watery stools
  • Abdominal cramps
  • Abdominal pain
  • Fever
  • Blood in the stool
  • Bloating

When to see a doctor

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

  • Your diarrhea persists beyond two days
  • 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 above 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 above 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
