About this assessment
Answer a few questions to understand whether vomiting may need emergency care
Start with how urgent this feels right now, then get personalized guidance on warning signs like dehydration, persistent vomiting, severe pain, and changes in alertness.
01
Vomiting in children can range from mild to urgent
Many children vomit with common illnesses and improve with rest and fluids. But sometimes vomiting is a sign that a child needs emergency evaluation, especially if there are signs of dehydration, trouble staying awake, severe belly pain, breathing problems, or vomiting that will not stop. This page is designed to help parents who are wondering when to seek emergency care for a vomiting child and when it may be appropriate to contact a pediatrician or monitor closely at home.
02
Signs a child vomiting may need the ER
Concerning behavior or breathing changes
Emergency care is important if your child is hard to wake, confused, unusually limp, has a seizure, or is having trouble breathing along with vomiting.
Severe pain, blood, or other high-risk symptoms
Seek urgent evaluation for severe or worsening belly pain, a swollen abdomen, blood or dark green vomit, a serious head injury, or vomiting with a stiff neck or severe headache.
03
When vomiting may be less likely to need emergency care
Short-lived vomiting with normal alertness
If your child is awake, responsive, and starts improving after a few episodes, home care may be reasonable while watching closely.
Able to take small amounts of fluid
Children who can keep down small sips and are still urinating may not need the emergency room, though they may still need pediatric advice.
No major red-flag symptoms
If there is no severe pain, no breathing trouble, no blood or green vomit, and no signs of dehydration, the next step may be home care or a call to your child’s doctor.

Frequently asked questions
When is vomiting an emergency in kids?
Vomiting may be an emergency if your child has signs of dehydration, cannot keep down fluids, is hard to wake, has trouble breathing, severe belly pain, blood or dark green vomit, or seems much sicker than with a typical stomach bug.
Should I go to the ER if my child keeps throwing up?
Persistent vomiting can need emergency care if your child cannot hold down even small sips of fluid, is becoming dehydrated, or has other warning signs like lethargy, severe pain, or abnormal behavior. If vomiting continues and you are unsure, it is reasonable to seek guidance promptly.
How do I know if vomiting and dehydration mean my child should go to the ER?
Warning signs include very little urine, no tears, dry mouth, sunken eyes, dizziness, unusual sleepiness, or vomiting that prevents any fluid intake. These can be signs that dehydration is becoming serious.
Does every child with vomiting need the emergency room?
No. Many children with vomiting improve with rest and careful fluids at home. The concern is higher when vomiting is severe, persistent, or happens with dehydration, severe pain, breathing problems, or changes in alertness.
