Migraine affects women disproportionately, with women being about two to three times more likely than men to experience it. Hormonal fluctuations—particularly changes in estrogen—are an important part of the explanation, but it would be an oversimplification to call migraine in women simply a “hormonal headache.”
Estrogen appears to have a particularly important role. The rapid fall in estrogen just before menstruation can increase the likelihood of a migraine attack. This is why many women notice a predictable relationship between their menstrual cycle and headaches. Menstrual migraine attacks can also be longer, more severe and more disabling than attacks occurring at other times of the cycle.
However, hormones are only one piece of the puzzle. Migraine is a neurological disorder involving abnormal sensitivity and activation of brain networks, including the trigeminovascular system. Genetic susceptibility, sleep disruption, stress, dehydration, missed meals, sensory stimuli and other individual triggers can all contribute. Hormonal fluctuations may lower the brain’s threshold for an attack, while these additional factors can determine whether a migraine actually occurs.
The hormonal connection also changes across a woman’s life. Migraine may begin or become more frequent around puberty, when hormonal cycling starts. Some women experience improvement during pregnancy when estrogen levels become relatively stable, although this is not universal. Conversely, perimenopause can be a difficult period because hormone levels become highly variable, and migraine—particularly menstrual migraine—may temporarily worsen.
Importantly, not every migraine in a woman is related to menstruation. Only a subset meets the criteria for menstrual migraine, while many women have attacks throughout the month. Therefore, attributing every headache to hormones can delay recognition of other triggers or the need for appropriate preventive treatment.
Women with recurrent headaches should maintain a headache and menstrual diary. Identifying whether attacks consistently occur around menstruation can help neurologists distinguish menstrual-related migraine from other patterns and tailor treatment accordingly.
Treatment should be individualised. Acute migraine medicines, preventive therapies and, in selected women, short-term treatment around the menstrual period may be considered. Hormonal strategies can sometimes help, but they are not appropriate for everyone and require careful assessment, particularly in women who have migraine with aura because some estrogen-containing contraceptive options may carry additional vascular risk.
The key message is that hormones matter—but migraine is much more than hormones. Understanding the interaction between hormonal changes and the brain can help women recognise their pattern earlier, avoid unnecessary suffering and receive more targeted treatment.
