About this assessment
Share what’s happening right now—including how severe the headache is, when the vomiting started, and any other symptoms—to get an assessment tailored to your child’s situation.
Headache and vomiting in kids can happen for several reasons. Sometimes it’s linked to a viral illness, fever, dehydration, or not eating enough. In other cases, a child headache with nausea and vomiting may be related to migraine, motion sickness, or another condition that needs closer attention. The key is looking at the full picture: how severe the headache is, whether your child can keep fluids down, how they are acting, and whether there are warning signs like neck stiffness, confusion, trouble walking, or a headache that wakes them from sleep.
A child with headache and vomiting may simply be dealing with a common illness, especially if there is fever, congestion, sore throat, or poor fluid intake. Vomiting can also make headaches worse by causing dehydration.
Some children have migraine symptoms that include headache, nausea, vomiting, light sensitivity, or needing to lie down in a dark room. This can happen even in younger kids.
Severe headache and vomiting in a child can sometimes point to a more urgent problem, especially if symptoms are sudden, intense, worsening, or paired with unusual behavior or neurologic symptoms.
Get immediate medical care if your child has a severe or sudden headache, trouble waking up, confusion, seizure, weakness, trouble speaking, stiff neck, breathing trouble, signs of dehydration, or vomiting after a head injury.
Reach out promptly if your child keeps vomiting, cannot drink, has a headache that is getting worse, has repeated episodes, has a fever with concerning symptoms, or has headache and vomiting at night or first thing in the morning.
If symptoms are mild and your child is alert, drinking some fluids, and improving, home monitoring may be reasonable. Watch for changes in pain, hydration, behavior, and any new symptoms.
It helps to know when the headache started, when vomiting began, whether one came first, and whether symptoms happen at night, after meals, or with fever.
A child who is playful between episodes is different from a child who is hard to wake, unusually quiet, confused, or in severe pain. These details matter.
Fever, neck pain, rash, dizziness, vision changes, abdominal pain, recent injury, or known migraine history can all change what causes headache and vomiting in children and how urgently they should be evaluated.
Common causes include viral illness, fever, dehydration, migraine, and sometimes stomach illness. Less often, headache and vomiting in a child can be linked to a more serious condition, especially if symptoms are severe, sudden, or come with confusion, neck stiffness, or trouble walking.
You should worry more if the headache is severe, starts suddenly, keeps getting worse, happens after a head injury, wakes your child from sleep, or comes with repeated vomiting, unusual sleepiness, confusion, weakness, seizure, or signs of dehydration.
No. Migraine is one possible cause, but not the only one. A child vomiting with headache may also have a viral infection, dehydration, fever-related illness, or another medical issue. Looking at the full symptom pattern helps narrow down what is most likely.
A child headache and vomiting at night can happen with migraine or illness, but it deserves closer attention if it is recurrent, wakes your child from sleep, or is paired with worsening pain, morning vomiting, or behavior changes. Those patterns should be discussed with a medical professional.
