Abdominal migraine symptoms adults experience include episodic stomach pain, nausea, and vomiting with no gut cause. Learn signs, triggers, and when to seek care.
Abdominal migraine symptoms adults present with are frequently mistaken for irritable bowel syndrome, food intolerance, or anxiety for months or even years before a correct diagnosis is made. The condition produces recurring episodes of moderate to severe stomach pain, often centered around the navel, paired with nausea, vomiting, and a loss of appetite, all without any identifiable structural problem in the digestive system. Between attacks, the person feels completely normal.
This pattern is the key: it comes, it goes, and nothing in the gut explains it.
Abdominal migraine is recognized by the International Headache Society as a formal migraine variant. To meet diagnostic criteria, a person must have had at least five episodes with all of the following features:
Crucially, the pain occurs without a headache in many cases. This is what throws both patients and clinicians off. Migraine is a brain condition, not just a head condition, and the gut is richly supplied with the same neural pathways that drive migraine in the skull.
The migraine brain processes sensory information differently than a neurotypical brain, and this includes signals from the gut. The vagus nerve and the enteric nervous system (the "second brain" in the gut) are deeply connected to the central nervous system. During a migraine episode, the same cascade of neurological events that triggers head pain can instead produce intense, wave-like abdominal symptoms.
Abdominal migraine in adults is often linked to a personal or family history of migraine with or without aura. Adults who experienced cyclical vomiting or unexplained stomach pain as children are particularly likely to carry this diagnosis into adulthood, sometimes transitioning toward more typical head-focused migraine over time.
Understanding the biology of CGRP (calcitonin gene-related peptide) helps explain why these episodes feel systemic rather than localized. For a deeper look at how CGRP drives migraine, see the CGRP explainer.
Because the headache is often absent, people tend to focus entirely on the gut. Here is what a typical episode looks like:

Duration and pattern
If you are tracking how often episodes occur each month, the monthly migraine days tool can help you build a clearer picture of frequency over time.
Abdominal migraine shares triggers with other migraine types:
| Trigger Category | Examples |
|---|---|
| Dietary | Skipping meals, chocolate, aged cheeses, caffeine changes |
| Sleep | Too little, too much, irregular schedule |
| Stress | Emotional stress, anxiety, post-stress "letdown" |
| Hormonal | Menstrual cycle fluctuations in adults with cycles |
| Sensory | Bright lights, strong smells, loud environments |
| Physical | Intense exercise, dehydration |
Not every person has the same triggers, and some attacks have no clear trigger at all. Systematic tracking is the most reliable way to identify your personal pattern. A structured diary approach is described in what to log in a migraine diary.
Abdominal migraine is a diagnosis of exclusion, meaning a clinician needs to rule out other causes of recurrent abdominal pain before landing on this label. That process typically involves:
Because this condition overlaps symptomatically with functional gastrointestinal disorders, it is worth mentioning to both your primary care clinician and any GI specialist that you want migraine variants considered. Many people benefit from tracking their episodes in detail to bring a clear account to the appointment.
If you are unsure whether your pattern looks episodic or chronic, the episodic vs. chronic migraine guide gives useful context for that conversation.
Not all recurrent abdominal pain is migraine. See a clinician promptly or go to an emergency room for:
An established pattern of abdominal migraine can still coexist with a new, different problem. When something feels different from your usual episodes, get it evaluated.
Abdominal migraine in adults is underdiagnosed partly because the episodes are easy to attribute to stress, diet, or a "sensitive stomach" without ever seeing the full pattern. Logging each episode with timestamps, symptom details, potential triggers, what you ate, how you slept, and how long it lasted transforms scattered data points into a coherent clinical picture.
The migraine symptom checker is a useful starting point if you want help organizing your symptoms. You can also use the tracking features in the app to log each episode consistently so that your clinician sees months of data at once rather than relying solely on your recall.
As always, bring your tracking data to a qualified healthcare provider before making any changes to how you manage your condition. Self-diagnosis has real limits here, and a clinician who can review your full history is essential for getting the right care.

Yes. Abdominal migraine is more common in children, but adults can and do experience it. Many adults with this condition had recurrent unexplained stomach pain as children before receiving a diagnosis later in life.
