A common trigger of migraine headaches in women are hormonal changes. Fluctuating estrogen can bring on a migraine, and many women report migraines during or right before their menstrual cycles when estrogen levels plummet.

Aged cheeses, processed foods and salty foods can trigger migraine headaches. Food additives like monosodium glutamate or MSG as well as the artificial sweetener aspartame can bring on a migraine. Wine and other alcoholic drinks and beverages with high levels of caffeine can also be culprits.
Intense physical exertion, stress at home or work, visual stimulation from bright lights and the sun and even sexual activity can trigger a migraine. Getting too much sleep or missing sleep can also be to blame.Learn more about Conditions & Diseases
