When to seek emergency care for vomiting, diarrhea and fever
As a parent, it’s natural to worry when your child has a fever, vomiting or diarrhea. While these symptoms are often linked to minor illnesses like the stomach flu or food poisoning, there are times when they may signal something more serious. Knowing when to seek emergency care can help keep your child safe.
Fever and vomiting: When to call a doctor
If your child has a low-grade fever and vomits once, it’s usually safe to monitor them at home and contact your pediatrician the next day. However, certain symptoms should not be ignored and may need urgent attention. Visit the pediatric emergency room (ER) if your child or toddler shows any of these additional symptoms:
Seek medical attention if your child:
- Is an infant younger than 3 months
- Has repetitive or forceful vomiting
- Has not urinated or has dry diapers
- Seems excessively sleepy or lethargic
- Cries inconsolably
- Has black or bloody vomit
- Has a fever:
- Over 100.4°F in infants under 3 months
- Over 102.2°F in children over 3 months
Fever and diarrhea: When to call a doctor
Diarrhea and fever are also common in children, but if your child has additional symptoms, it may be time to seek emergency care. Go to the ER if diarrhea and fever are accompanied by:
- Blood in the stool
- Signs of dehydration (dry mouth, sunken eyes, no tears when crying)
- No urination or dry diapers
- Lethargy or extreme fatigue
- Inconsolable crying
- High fever (same thresholds as above)
