Various precipitants of migraine events have been identified:
Hormonal changes, such as those accompanying menstruation (common), pregnancy, and ovulation
Excessive or insufficient sleep
Medications (eg, vasodilators, oral contraceptives)
Exposure to bright or fluorescent lighting
Strong odors (eg, perfumes, colognes, petroleum distillates)
Cold stimulus (eg, ice cream headaches)
Lack of exercise
Fasting or skipping meals
Information on dietary triggers is often conflicting. Foods and food additives that have been suggested as potential precipitants of migraine include:
Artificial sweeteners (eg, aspartame, saccharin)
Monosodium glutamate (MSG)
Foods containing tyramine (eg, aged cheese)
