If your child repeatedly has severe tummy pain but medical assessment does not identify another clear cause, you may be surprised to hear the term abdominal migraine. It can sound confusing when there is no headache, but this recognised migraine-related condition mainly causes episodes of abdominal pain.
The pain is often around the middle of the tummy or near the belly button and may come with nausea, vomiting, loss of appetite or paleness. You may notice that your child feels unwell for several hours before returning to normal between attacks, while treatment can include regular meals, good hydration, consistent sleep and individualised migraine care.
What Is Abdominal Migraine?
Abdominal migraine is a migraine-related condition where repeated episodes of tummy pain are the main symptom. Under ICHD-3 criteria, headache is absent during the abdominal attacks, which can make the condition seem different from a typical migraine headache.
What makes abdominal migraine different is the pattern of significant abdominal pain, migraine-like symptoms and periods when your child returns to normal health. If the pain happens almost every day without clear symptom-free periods, you should speak to their doctor so other possible causes can be considered.
What Are the Main Symptoms of Abdominal Migraine?
The main symptom of abdominal migraine is repeated moderate or severe tummy pain, usually around the belly button. You may also notice nausea, vomiting, loss of appetite or paleness, with the pain sometimes making it difficult for your child to carry on with normal activities.
One useful clue is how your child feels after an attack. Under ICHD-3 criteria, your child should return to their usual health and be symptom-free between attacks. Ongoing symptoms between episodes may suggest that another diagnosis should be considered.
Why Can Abdominal Migraine Happen Without a Headache?
Migraine does not always cause a headache, particularly in children. Your child may instead experience tummy pain, nausea or pallor, which can make the connection with migraine less obvious.
Under ICHD-3 criteria, headache does not occur during an abdominal migraine attack. If head pain consistently occurs during the same episode, the clinician may consider whether another migraine diagnosis fits better. If headaches develop at other times as your child grows, their migraine pattern can be reassessed.
What Does an Abdominal Migraine Attack Look Like?
An abdominal migraine attack may start with tummy pain, followed by nausea, vomiting, pallor or a loss of appetite. Under ICHD-3 criteria, untreated or unsuccessfully treated abdominal migraine attacks last between two and 72 hours.
The pattern can vary between attacks, but similar symptoms and recovery periods may become noticeable over time. Noticing whether each episode follows a similar pattern can provide useful information for your child’s clinician.
What Causes Abdominal Migraine?
The exact cause of abdominal migraine is not fully understood. It is considered part of the migraine spectrum, and interactions between the brain, nervous system and digestive system may contribute to symptoms such as pain, nausea and vomiting.
This does not mean the symptoms are psychological or imagined; your child can have severe pain even when tests show no clear digestive problem. You may also notice attacks are more likely when sleep, meals or hydration are disrupted, although triggers vary from child to child.
What Can Trigger an Abdominal Migraine Attack?
Triggers can vary from child to child, and some attacks may happen without an obvious reason. You may notice links with missed meals, dehydration, irregular sleep or stress, but these factors do not affect every child in the same way.
Rather than removing lots of foods, focus on regular meals, enough fluids and a consistent sleep routine. You can use a simple symptom diary to spot patterns and discuss any repeated triggers with your child’s doctor before making major changes.
Clinical Tip
Avoid removing several foods from your child’s diet based on one or two attacks. If a possible trigger appears repeatedly, record it in the symptom diary and discuss it with their clinician before making significant dietary restrictions.
Abdominal Migraine Diagnostic Features at a Glance
| ICHD-3 feature | What it means |
| Number of attacks | At least five episodes |
| Pain location | Midline, around the belly button or poorly localised |
| Pain quality | Dull or “just sore” in character |
| Pain severity | Moderate or severe and significant enough to affect normal activities |
| Associated symptoms | At least two of loss of appetite, nausea, vomiting or pallor |
| Attack duration | 2–72 hours if untreated or unsuccessfully treated |
| Between attacks | Your child returns to normal health |
| Other causes | Another condition should not better explain the symptoms |
Different diagnostic frameworks are used for abdominal migraine. This article uses the ICHD-3 criteria; Rome IV criteria differ in areas such as attack duration and associated symptoms. Under ICHD-3, the abdominal pain should have at least two of the three features relating to location, quality and intensity. These criteria help clinicians recognise the pattern, but diagnosis still depends on your child’s complete history and examination rather than simply ticking boxes.
How Is Abdominal Migraine Diagnosed?
There is no single test or scan that can confirm abdominal migraine in your child. Diagnosis is mainly based on the pattern of attacks, including tummy pain, nausea, vomiting, loss of appetite or pallor, while making sure another condition does not better explain the symptoms.
Doctors will also consider your child’s symptoms between attacks and whether there are signs of gastrointestinal or kidney problems. You can help by describing several typical episodes, as a clear history is often more useful than repeated tests when the overall pattern is reassuring.
What Other Conditions Can Look Like Abdominal Migraine?
Recurrent tummy pain can have many causes, so abdominal migraine is only one possible explanation. Your child’s doctor may consider conditions such as constipation, urinary infections, coeliac disease, reflux, inflammatory bowel disease and other digestive problems.
Abdominal migraine usually causes clear attacks with periods when your child feels completely well. If symptoms continue between attacks, or you notice fever, persistent vomiting or changing pain, you should speak to their doctor so other causes can be considered.
How Is Abdominal Migraine Different from Cyclical Vomiting Syndrome?
Abdominal migraine and cyclical vomiting syndrome can both cause repeated episodes with normal health between attacks, and both are recognised as migraine-related episodic conditions. A key difference is which symptom dominates: significant abdominal pain is central to abdominal migraine, while intense recurrent nausea and vomiting are the main features of cyclical vomiting syndrome. Clinicians also consider the timing and pattern of attacks against recognised diagnostic criteria.
The distinction is not always obvious when your child has both pain and vomiting. Your clinician will look at which symptom is most severe and consistent, how attacks develop and whether the overall pattern meets recognised diagnostic criteria.
Clinical Note
A child’s symptom pattern can change over time. If vomiting becomes the dominant symptom, headaches start occurring during the abdominal episodes or your child stops returning to normal between attacks, the diagnosis should be reviewed rather than assuming the pattern is still abdominal migraine.
When Does Abdominal Pain Need Urgent Medical Attention?
Even if your child has been diagnosed with abdominal migraine, you should not assume every new episode of tummy pain is caused by it. A significant change from their usual pattern or new warning signs should be assessed.
Call 999 or go to A&E if your child has dark-green (bilious) vomit, vomits blood, becomes pale and floppy, becomes very drowsy or difficult to wake, has severe abdominal pain that is not controlled with simple pain relief, or develops testicular pain in boys.
Contact NHS 111 or seek an urgent GP assessment if your child has unexplained weight loss, jaundice, blood in the stool or urine, a swollen tummy, constant pain lasting more than a day despite pain relief, fever or other symptoms continuing for more than five days, or becomes unusually thirsty or starts passing significantly more or less urine than normal.
UK Guidance Note
Alder Hey advises emergency assessment for features such as becoming pale and floppy, dark-green (bilious) vomit, blood in vomit, marked drowsiness or difficulty waking, severe uncontrolled abdominal pain, or testicular pain in boys. Other warning signs, including jaundice, unexplained weight loss, a swollen tummy or blood in the stool or urine, should prompt NHS 111 or urgent GP advice.
Will My Child Need Tests or Scans?
Your child may not need tests or scans if their symptoms fit abdominal migraine and their examination is reassuring. You can expect the doctor to consider their growth, tummy symptoms, appetite, stools, urine, fever and general health before deciding whether further tests are needed.
If there are warning signs, selected blood, urine or stool tests may be recommended, while scans are not always needed for recurring tummy pain. You can ask what each test is intended to look for and why it is or is not considered necessary for your child.
What Can You Do During an Abdominal Migraine Attack?
During an attack, your child may need to stop normal activities and rest in a calm environment. You can offer small, regular amounts of fluid if they can tolerate them, and food can be given according to their appetite rather than being forced.
If your clinician has provided a treatment plan, follow it and use recommended medicines as advised. You should seek medical advice if vomiting continues, your child cannot stay hydrated or the pain changes from their usual pattern.
Can Abdominal Migraine Be Prevented?
You may not be able to prevent every abdominal migraine attack, but a consistent routine can help reduce avoidable triggers. Regular meals, good hydration and steady sleep patterns are particularly useful, especially when changes in routine seem to trigger symptoms.
Your child can usually continue normal activities such as school, exercise and seeing friends when they are well. If stress seems to play a role, simple ways of managing school pressure or changes in routine may also help without making your child’s lifestyle unnecessarily restrictive.
How Can You Tell Whether Treatment Is Helping?
Improvement does not always mean that every attack disappears immediately. You can look for changes in how often attacks occur, how long they last, how severe the pain or vomiting becomes and how quickly your child returns to normal afterwards. Fewer missed school days or less disruption to activities can also be useful signs that management is helping.
A symptom diary can make these changes easier to recognise over time. If attacks remain frequent, become more severe or continue to interfere significantly with eating, hydration, school or everyday activities, discuss the pattern with your child’s clinician so the diagnosis and treatment plan can be reviewed.
What Medicines Can Be Used for Abdominal Migraine?
There is less high-quality evidence for treating abdominal migraine than conventional migraine headaches, so treatment needs to be tailored to your child. Simple pain relief may sometimes be used, while medicines for nausea or vomiting may be considered depending on their age, symptoms and overall health.
If attacks are frequent or affecting school and daily life, you may be offered preventive treatment by a clinician experienced in childhood migraine. You should not start medicines from an online list, as the correct dose, side effects and suitability can vary between children.
Evidence Note
Evidence specifically for treating childhood abdominal migraine remains limited. A 2025 systematic review and network meta-analysis included several paediatric functional abdominal pain disorders, including abdominal migraine. Across the overall evidence, CBT and hypnotherapy showed moderate-certainty benefit, but this does not establish the same level of benefit specifically for children with abdominal migraine, and evidence for most other interventions remained uncertain.
When Might Your Child Need Specialist Review?
If attacks are frequent, severe, disrupting school or not improving with initial management, your child may benefit from review by a clinician experienced in childhood migraine or recurrent abdominal pain. Specialist assessment may also be useful when the diagnosis is uncertain or the symptom pattern changes.
A specialist can review whether abdominal migraine remains the most likely diagnosis, decide whether further investigation is appropriate and discuss treatment options according to your child’s age, symptoms and how much the attacks affect everyday life.
Why Is a Symptom Diary So Helpful?
A symptom diary can help you and your child’s clinician spot a clearer pattern in their tummy pain. For each attack, note when it started and ended, where the pain occurred, and whether symptoms such as nausea, vomiting or loss of appetite were present.
You can also record sleep, missed meals, fluid intake and any headaches or symptoms between attacks. Bringing a short record to appointments can make it easier for the clinician to understand the pattern and decide whether treatment needs adjusting.
Myth vs Fact
| Myth | Fact |
| Abdominal migraine always causes a headache. | No. Under ICHD-3 criteria, headache does not occur during the abdominal episode. |
| Tummy pain means there must be a digestive disease. | Not always. Abdominal migraine is a recognised migraine-related condition, although other causes need to be considered. |
| A normal scan proves abdominal migraine. | No. There is no single test that confirms it; diagnosis mainly depends on the clinical pattern. |
| Every child needs extensive testing. | No. Testing is guided by the history, examination and presence of warning signs. |
| Children with abdominal migraine will always have it permanently. | No. Abdominal attacks can improve with age, although migraine headache may develop later. |
How Can You Manage Abdominal Migraine at School?
Abdominal migraine can affect school because attacks may be severe even when your child seems completely well between episodes. It can help to explain the diagnosis to school staff so they understand that your child may need to rest and follow their treatment plan during an attack.
Try to maintain normal school attendance when your child is well, while making sure staff know what to do if symptoms occur. If attacks are causing frequent absence or affecting everyday activities, speak to your child’s doctor so their treatment can be reviewed.
Do Children Grow Out of Abdominal Migraine?
Abdominal migraine can change as your child grows. You may notice that tummy symptoms become less frequent, while migraine headaches develop later, and the International Headache Society states that most children with abdominal migraine go on to develop migraine headaches.
This does not mean your child will continue having abdominal attacks indefinitely. If they develop new headaches or other symptoms, tell their clinician about the previous diagnosis so their symptoms can be reassessed and treatment adjusted if needed.

- There is no single blood test or scan that confirms abdominal migraine.
- New or unusual abdominal symptoms should not automatically be assumed to be another migraine attack.
- Treatment is individualised because high-quality abdominal migraine-specific evidence remains limited.
- Regular meals, hydration, sleep and identifying individual triggers can form part of management.
- Many children stop having abdominal migraine as they grow, although migraine headaches may occur later.
FAQs
1. What is abdominal migraine in children?
Abdominal migraine is a migraine-related condition where recurrent episodes of moderate to severe tummy pain are the main symptom. Attacks may also cause nausea, vomiting, loss of appetite and paleness, with the child usually returning to normal between episodes.
2. What are the symptoms of abdominal migraine in children?
Common symptoms include significant pain around the belly button or middle of the tummy, nausea, vomiting, loss of appetite and pallor. Episodes can last for several hours and may interfere with school, play and normal activities.
3. Can abdominal migraine happen without a headache?
Yes. Under ICHD-3 criteria, headache is absent during the abdominal migraine attack. If headache consistently occurs during the same episode, the clinician may consider whether another migraine diagnosis is more appropriate.
4. How is abdominal migraine diagnosed?
There is no single blood test or scan that confirms abdominal migraine. Diagnosis is mainly based on the pattern of recurrent attacks, associated symptoms and symptom-free periods between episodes, while ensuring that another condition does not better explain the symptoms.
5. What can trigger abdominal migraine in children?
Possible triggers include missed meals, dehydration, irregular sleep and stress. Triggers vary between children, so keeping a symptom diary can help identify whether a particular pattern is linked to attacks.
6. How long does an abdominal migraine attack last?
Under the ICHD-3 diagnostic criteria, untreated or unsuccessfully treated attacks last between two and 72 hours, with the child returning to their usual health and being symptom-free between attacks.
7. How is abdominal migraine treated in children?
Treatment may include regular meals, good hydration, consistent sleep and avoiding recognised triggers. Depending on the frequency and severity of attacks, a clinician may also recommend medicines for symptoms or preventive migraine treatment.
8. When should abdominal pain in a child be assessed urgently?
Urgent assessment is important if abdominal pain is accompanied by unexplained weight loss, jaundice, blood in the stool or urine, a swollen tummy, constant pain lasting more than a day despite pain relief, or fever or other symptoms continuing for more than five days. Call 999 or go to A&E if your child becomes pale and floppy, has dark-green (bilious) vomit, blood in vomit, marked drowsiness or difficulty waking, severe abdominal pain despite simple pain relief, or testicular pain in boys.
9. Do children grow out of abdominal migraine?
The way migraine presents can change as a child grows. Abdominal symptoms may become less prominent, while migraine headaches may develop later, so ongoing symptoms should be reviewed if the pattern changes.
10. Can abdominal migraine be prevented?
Not every attack can be prevented, but a consistent routine may reduce the likelihood of episodes for some children. Regular meals, adequate fluids, sufficient sleep and identifying individual triggers can all form part of a prevention plan.
Final Thoughts: Understanding Abdominal Migraine in Children
Abdominal migraine can be difficult to recognise because tummy pain, rather than headache, is often the main symptom. Recurrent attacks of significant abdominal pain with nausea, vomiting, loss of appetite or paleness, followed by complete recovery between episodes, can provide important clues. Keeping a symptom diary and maintaining regular meals, good hydration and consistent sleep may also help manage the condition and identify possible triggers.
If your child’s attacks become more frequent, change in character or begin to affect school and everyday activities, it is important to review their symptoms with a clinician.
