Headache associated with hormonal fluctuations

Changes in sex-hormone levels during menarche, menstruation, pregnancy, and menopause may affect the prevalence and character of migraine and other types of headaches. Migraine occurring with menses may be characterized as menstrual migraine, menstrual-associated migraine, and non-migrainous perimenstrual headache. Migraine typically improves during pregnancy, mostly in the second and third trimesters. After menopause, when sex hormone levels stabilize, most women have improvement.
