What is an abdominal migraine?
An abdominal migraine causes recurrent, severe stomach pain, often around the belly button, with possible nausea, vomiting, and pale skin. It typically affects children but can occur in adults. Each episode can last from 2 to 72 hours and is not caused by infection or structural issues. The condition shares neurological pathways with classic migraine headaches.
What are the symptoms of abdominal migraine?
Symptoms include intense, midline abdominal pain, nausea, vomiting, loss of appetite, and pallor or flushing. Episodes may last hours to days and recur in cycles. Unlike stomach flu, there is no infection. Children may miss school during attacks, and adults may experience stress-related flare-ups.
What is abdominal migraine in adults?
Although abdominal migraine is more common in children, adults can experience it too. In adults, it often appears as recurring abdominal pain linked to stress, hormones, or migraine history. Diagnosis can be challenging, as symptoms may resemble IBS or gastritis.
What causes abdominal migraine?
While research continues, the exact cause of abdominal migraine is not yet fully understood. It’s thought to be linked to genetics, stress, hormonal changes, and the gut-brain connection. Many people with abdominal migraine have a family history of migraine. The brain’s pain pathways and hypersensitivity of the nervous system likely play key roles.
What triggers an abdominal migraine?
Triggers can include stress, fatigue, skipped meals, dehydration, or foods such as chocolate, cheese, or processed meats. Hormonal changes and lack of sleep can also contribute. Identifying and managing triggers through a symptom diary often helps reduce attack frequency.
How is abdominal migraine diagnosed?
Diagnosis is based on clinical history and symptom patterns. There are no specific lab tests, but other causes of abdominal pain are ruled out through examination and, if needed, imaging or blood tests. The International Classification of Headache Disorders (ICHD) criteria are often used.
How is abdominal migraine treated?
Treatment involves both acute relief and prevention. During an attack, rest, hydration, and prescribed medications such as NSAIDs or antiemetics can help. Preventive strategies include trigger management, regular routines, and in some cases, low-dose prophylactic medication. At Brisbane Headache and Migraine Clinic, the non-drug Watson Headache Approach may be used to address cervical spine sensitivity that contributes to symptoms.
Can abdominal migraine be prevented?
Maintaining regular sleep, balanced meals, hydration, and managing stress can help prevent episodes. Avoiding identified triggers and following a personalised care plan can reduce attacks over time.
Is abdominal migraine serious?
Abdominal migraine is not dangerous, but it can affect quality of life through missed school or work and recurring discomfort. Professional assessment is important to exclude other medical causes and develop an effective treatment plan.
Abdominal Migraine vs Cyclic Vomiting Syndrome
Though they’re often mistaken for the same condition, there are differences between Abdominal Migraine and Cyclic Vomiting Syndrome.
Cyclic vomiting syndrome refers to waves of intense nausea, vomiting, and other stomach problems for no obvious reason. Cyclic vomiting syndrome may also last up to 10 days, compared to 3 days for Abdominal Migraine. While you may experience nausea and vomiting as a symptom of Abdominal Migraine, Abdominal Migraine is often experienced purely as abdominal pain.
In both cases, sufferers can experience loss of appetite and pale skin during an attack.
Sensitised Brainstem
In those individuals that may be suffering from Abdominal Migraine and have no underlying pathology or disorder that can be recognised, another known cause may be due to a sensitised brainstem.
A sensitised brainstem will perceive non-threatening stimuli (such as eating certain foods) and create pain to be felt where the sensory information was originally detected. This hyper-excitability of the pain sensation is due to the heightened arousal and sensitive brainstem. A sensitive brainstem will relay the sensory information to the brain but will heighten the sensation so that the brain perceives the information as painful.
