The Migraine Threshold

While some people may be very sensitive to specific triggers, others may be vulnerable only when several triggers combine at once e.g. a deadline at work, together with long hours and a missed meal may bring on an attack in someone who can usually tolerate any one of those triggers individually.

If you find that this happens to you, then you may be able to limit your exposure to migraine by avoiding the 'avoidable' factors such as alcohol, food, late nights etc at times when the 'unavoidable' ones are present (hormonal changes, weather changes etc).

Summary

Everyone triggers are individual to them
Some people appear not to have any trigger factors at all
Foodstuffs are not the only trigger factors
Keep a Migraine Diary to identify possible triggers
Remember that one trigger factor on its own may not bring about an attack, but a combination of them might.
