Migraine is a complex neurologic disorder, and triggers, protective factors, and symptoms can vary widely between patients.1,4

Read below and explore this evidence-based educational resource designed to help healthcare professionals support patients in identifying and managing migraine triggers, while reinforcing shared decision-making and positive health behaviors.

Commonly reported migraine triggers

Multiple factors may interact to culminate in a migraine episode, and not all patients respond to the same triggers. Commonly reported triggers include1-7:

  • Stress, one of the most frequently reported triggers and a contributor to chronification
  • Sleep disturbance, which may have a bidirectional relationship with migraine
  • Dietary factors, including skipped meals, dehydration, and certain foods
  • Light exposure, such as glare, flickering, or bright artificial light
  • Weather changes, including atmospheric pressure and temperature shifts
  • Hormonal fluctuations, particularly around menstruation

Importantly, trigger avoidance alone is often unsuccessful and may negatively affect quality of life.3

Migraine triggers are defined as measurable exposures associated with an increased probability of an attack over a short period of time.4

Identifying a single trigger may not always be possible.3,4,5,8

  • Triggers and protective factors are unique to each patient.
  • Premonitory symptoms may make trigger identification more difficult.
  • A preventive, individualized approach is often most effective.

Practical strategies to support patients include3,4:

  • Encouraging healthy lifestyle (regular sleep, meals, hydration, and physical activity)
  • Using headache diaries or calendars to identify patterns over time
  • Promoting shared decision-making rather than strict trigger avoidance
