Migraine Triggers

What triggers a migraine?

Certain triggers may increase your risk of a migraine attack. While triggers do not directly cause migraines, they are thought to activate abnormal brain activity in people who are prone to get migraine headaches.1

Tracking your migraines

Migraine triggers vary from person to person, and a single trigger won’t necessarily cause a migraine headache every time you’re exposed to it.1 A combination of migraine triggers may be more likely to bring on a migraine attack.2 And sometimes migraines come on spontaneously — during sleep, for instance.3

It’s a good idea to keep track of the factors that may trigger your migraines. By avoiding your triggers, you may be able to reduce the number of migraine headaches you get.1
