Women are two to three times more likely than men to experience migraines. Here is what is known about the hormonal and neurological drivers — and the evidence for each treatment approach.
Before puberty, migraine affects boys and girls at roughly similar rates. After puberty that changes sharply and permanently: women end up two to three times more likely to have migraines than men, a gap that persists through the reproductive years and only narrows again after menopause. That specific timing pattern is the biggest clue researchers have, and it points squarely at reproductive hormones — particularly estrogen — as a central driver.
The mechanism: estrogen withdrawal, not estrogen level
The leading explanation, generally called the estrogen withdrawal theory, is more precise than “hormones cause migraines.” It is not how much estrogen is circulating that matters most — it is the rate and direction of change. A sharp drop in estrogen, of the kind that happens in the days just before menstruation, is a well-established trigger for migraine without aura. By contrast, periods of high or rising estrogen — such as with certain combined hormonal contraceptives — are more associated with triggering migraine with aura in susceptible women. This distinction matters clinically: it is why some hormonal treatments help one presentation of migraine while making another worse, and why “just take hormones” and “just avoid hormones” are both oversimplifications of what the evidence supports.

Menstrual migraine specifically
When migraine attacks cluster tightly around menstruation — generally defined as occurring from two days before to two days after the start of a period — it is classified as menstrual migraine. Migraine with a menstrual link affects a substantial share of women who get migraines at all, with estimates in the broad range of 18% to 25% of female migraine patients showing this clear cyclical pattern; some estimates for perimenstrual worsening specifically run considerably higher. These attacks have a distinct clinical profile: research consistently finds they tend to be longer, more severe, and less responsive to standard acute treatment than migraines unrelated to the cycle.
Other reproductive milestones
- Puberty is where the sex gap opens — before it, rates in boys and girls are roughly equal
- Pregnancy generally brings improvement for migraine without aura, often by the second trimester, as estrogen stabilises at a sustained high level rather than fluctuating
- Migraine with aura is a partial exception — the high-estrogen state of pregnancy is associated with increased aura frequency in some women, and since aura and pregnancy each raise stroke risk slightly, clinicians watch that combination more closely even though absolute risk stays low
- Perimenopause is a period of worsening migraine for many women, driven by the same volatile swings behind hot flashes and sleep disruption
- Menopause itself, once levels settle at a stable if lower baseline, is associated with improvement for many women
- The common thread is fluctuation, not level — stability, at whatever baseline, is the more migraine-friendly state
What the evidence supports for treatment
This is genuinely a case where the right approach depends on the specific pattern, so a doctor’s involvement in tailoring treatment matters more here than in most wellness topics. The broad categories with evidence behind them:
- Acute treatment during predictable menstrual migraine. Because these attacks tend to be more severe and harder to treat, they sometimes warrant a different approach than standard as-needed migraine medication — longer-acting triptans, or in some cases short-term preventive use of a triptan or estrogen supplementation started a few days before the expected attack, are strategies used clinically for women with predictable cycles.
- Hormonal contraception can be used deliberately to reduce estrogen fluctuation. Continuous or extended-cycle combined contraceptives — skipping the hormone-free week that would otherwise trigger an estrogen drop — are one evidence-based strategy for menstrual migraine, though the choice of method depends heavily on whether a woman has migraine with or without aura, given the stroke-risk consideration with estrogen-containing contraceptives in migraine-with-aura patients specifically. Progesterone-only options are often preferred in that situation for exactly this reason.
- Hormone therapy around perimenopause and menopause can help migraine linked to estrogen withdrawal by keeping levels more stable, and may be considered alongside its role in managing vasomotor symptoms — but as with contraceptive choices, the type, dose, and route matter, and this is a decision made with a doctor weighing migraine history against broader menopausal hormone therapy risk factors.
- Tracking. A headache diary alongside menstrual cycle tracking is a low-cost, high-value first step regardless of what comes next, since confirming an actual cyclical pattern rather than assuming one is what makes every downstream treatment decision more precise.
The practical takeaway
The size of the sex gap in migraine — two to three times higher in women, opening at puberty and narrowing after menopause — is one of the clearer hormone-linked patterns in neurology, not a vague correlation. But “hormonal” does not mean “untreatable” or “just something to live with.” Menstrual migraine in particular is a recognised, well-studied subtype with specific treatment strategies that differ from general migraine care, which is exactly why pattern tracking and a conversation with a doctor familiar with hormonal migraine tend to produce better results than generic over-the-counter management.
This is general information about migraine research, not medical advice. Migraine treatment, especially involving hormonal therapy, should be worked out with a doctor familiar with your specific history.
