Abdominal migraine

Abdominal migraine (AM) is a syndrome which presents as recurrent episodes of severe abdominal pain, coupled with autonomic symptoms, nausea and emesis. Historically it has tended to be a pediatric diagnosis, but is now increasingly seen in adults. It is one of the functional gastrointestinal disorders (FGIDs) 1. Similar to the other FGIDs its pathogenesis remains unresolved despite extensive ongoing work.



Clinical presentation

Diagnosis employs both the International Classification of Headache Disorders diagnostic criteria and Rome III Criteria. Establishing the diagnosis requires at least two discrete episodes in a one-year period 1.

These episodes must consist of:

  1. paroxysmal episodes of intense, acute periumbilical pain that lasts for one hour or more
  2. intervening periods of usual health lasting weeks to months
  3. pain interferes with normal activities
  4. pain is associated with two of the following:
    • anorexia
    • nausea
    • vomiting
    • headache
    • photophobia
    • pallor
  5. No evidence of an inflammatory, anatomic, metabolic, or neoplastic process considered that explains the subject’s symptoms
