What Triggers Hormonal Migraines in Women?
Birth control pills as well as hormone replacement therapy during menopause have been recognized as migraine triggers in some women. As early as 1966, investigators noted that migraines can become more severe in women taking birth control pills, especially those containing high doses of estrogen. The frequency of side effects, such as headache, decreased in those who took birth control pills containing lower doses of estrogen and did not occur in those who took birth control pills containing progesterone.
