Menstrual migraine: understanding and relieving headaches related to menstruation

Studies show that menstrual migraine attacks tend to be longer and more intense than migraines occurring outside the menstrual period, and they respond less effectively to conventional pain relievers. Understanding this hormonal link and discussing it with your doctor allows you to consider strategies tailored to your profile and improve your menstrual comfort.

A menstrual migraine is diagnosed when:

• An attack systematically appears within a window spanning from 2 days before to 3 days after the first day of your period;
• This recurs across at least two consecutive cycles (IHS criteria);
• It is predominantly a migraine without aura, although rare cases with aura have been documented.

A migraine, whether linked to your period or not, is recognized by the same signs. However, the experience differs from one woman to another. The pain can affect only one side of the head or both. It can beat like a pulse or feel more diffuse. Depending on the profile, it may be accompanied by nausea, vomiting, or sensitivity to light and sound.

A migraine attack typically unfolds in three stages: the warning signs, the pain itself, and then the recovery phase. For some women, an aura is also present.

The aura involves temporary symptoms that do not cause lasting harm, preceding or accompanying the onset of pain. Most often, these symptoms affect vision: bright spots, zigzag lines, or blurry areas in the visual field. They can also manifest as tingling sensations or difficulty finding words.

The warning signs (referred to by doctors as the prodrome) appear anywhere from a few hours up to one or two days before the attack, depending on the person: unusual fatigue, irritability, difficulty concentrating, specific food cravings, or repeated yawning.

The recovery phase (the postdrome) follows the resolution of the pain. Many women describe experiencing brain fog, marked fatigue, trouble concentrating, or persistent irritability during this time.

Both of these phases are fully part of the migraine experience. Yet, they are frequently ignored, even though they can weigh just as heavily as the attack itself on daily life.

Therefore, the difference with a menstrual migraine does not stem from its nature, but from its hormonal trigger and its timing of occurrence. Its specific characteristics include:

• It returns at a fixed time, in direct alignment with the menstrual cycle;
• It is often more intense, with attacks lasting an average of 24 hours, compared to 12 hours for migraines occurring outside of the menstrual window (European study, 2021).

• The International Classification of Headache Disorders (ICHD-3) distinguishes between two sub-types:
• Pure Menstrual Migraine (PMM): attacks occur exclusively within the perimenstrual window (between Day -2 and Day +3 of the cycle, where Day 1 represents the first day of the period) and never at any other time during the cycle. This accounts for about 10% of women who experience migraines.
• Menstruation-Related Migraine (MRM): attacks repeatedly occur around the time of the period but can also manifest at other points during the cycle. This is by far the most frequent form.

In both cases, the central triggering mechanism remains the same: the drop in estrogen levels.

It is not so much the absolute level of estrogen but the speed of its fluctuation that triggers the attack. A 50% drop in estrogen levels within 24 hours can increase the excitability of the trigeminovascular system, which is responsible for 70% of pain sensations (Neuroscience Letters, 2020). Cases of estrogen dominance can also modulate this sensitivity and promote increased severity of attacks.

• Estrogen modulates serotonin: a decrease promotes blood vessel dilation and meningeal inflammation.
• Prostaglandins, released during menstruation, increase nerve sensitivity and worsen the pain.

The primary mechanism identified is the sudden drop in estradiol levels (the most active form of estrogen) that occurs at the end of the luteal phase, right before your period. This rapid hormonal variation impacts several neurological and vascular systems:

• It influences the synthesis of serotonin, a key neurotransmitter in pain regulation and vasoconstriction. A drop in estrogen levels decreases the availability of serotonin, promoting cerebral vasodilation and consequently triggering migraine pain.
• It alters the sensitivity of the trigeminovascular system, the neural pathway involved in the genesis of migraines.
• It promotes the synthesis of pro-inflammatory prostaglandins, notably via uterine contractions—which explains the connection between dysmenorrhea (painful periods) and menstrual migraines.

Thus, it is not a permanently low level of estrogen itself that causes the migraine, but rather the speed and scale of its drop—which explains why some women are much more sensitive to it than others.

On a standard 28-day cycle (provided as an indication, as every cycle is unique):

• • Day -2 to Day +3 (perimenstrual window): This is the primary risk window, during which estrogen levels plummet following the post-ovulatory peak. This is the temporal zone defined by the ICHD-3 criteria.
• • Around ovulation (towards Day 13-Day 15): Some women also suffer from a migraine during the post-ovulatory drop in estrogen, which is less documented but very real.

Outside of these windows, hormonal levels are relatively stable, explaining why attacks are less frequent mid-cycle.

Hormonal fluctuation is the central factor, but several elements can lower the threshold for an attack and worsen symptoms:

• Chronic or acute stress (particularly during the premenstrual phase, when stress tolerance is naturally reduced)
• Sleep disruptions (insomnia, hypersomnia, changes in sleep rhythm)
• Dehydration and irregular meals (reactive hypoglycemia)
• Magnesium deficiency, which is common before periods and known to lower the migraine threshold
• Imbalances in the prostaglandin balance (omega-6 to omega-3 ratio)
• Alcohol, foods rich in tyramine (aged cheeses, cured meats), and excessive amounts of caffeine

Menstrual migraines share the characteristics of a classic migraine, with a few notable specificities:

• Throbbing, often one-sided pain (hemicrania), ranging from moderate to severe intensity
• Worsening with physical effort, light (photophobia), and sound (phonophobia)
• Nausea, sometimes vomiting
• Occurrence within the Day -2/Day +3 window repeatedly for at least 2 out of 3 cycles
• Longer attacks that are often less responsive to standard acute treatments (pain relievers, anti-inflammatories, or even triptans) than those occurring outside the menstrual window
• Frequent absence of aura (unlike certain non-hormonal forms, menstrual migraines are most commonly without aura)
• Possible association with other premenstrual symptoms: intense fatigue, irritability, bloating, abdominal pain

A menstrual migraine attack lasts on average between 4 and 72 hours. However, it tends to be longer than migraines that occur outside the perimenstrual window. Attacks extending over 2 to 3 days are frequently reported, sometimes coinciding with the entire duration of the period.

This extended duration is explained by the persistence of the estrogen drop during the days of menstruation, maintaining a state of neurological vulnerability for longer than a single, isolated trigger would.

The relationship between hormonal contraception and migraines is complex and highly individual. Here are the key points to know:

• In women with no contraindications, the combined estrogen-progestin pill, by suppressing natural cycle fluctuations, can reduce menstrual migraines. However, the pill-free week (or placebo week) triggers an estrogen drop that can itself cause an attack.
• The progestin-only pill or the hormonal IUD (progestin alone) can sometimes worsen migraines in certain women, or have no effect at all.

Important: migraine with aura is a strict contraindication to the combined estrogen-progestin pill, regardless of age, and must absolutely be discussed with a doctor. The synthetic estrogens it contains increase the risk of ischemic stroke, which is already higher in individuals suffering from migraines with aura. The World Health Organization classifies this combination under Category 4 of its medical eligibility criteria for contraceptive use, meaning it is a method that should not be used.

For migraines without aura, age also becomes a factor according to the WHO: from the age of 35, starting the combined pill is not recommended, and its continuation should be avoided; before the age of 35, both starting and continuing it remain not recommended but feasible under medical supervision. Contraceptives without estrogen (progestin-only pill, hormonal IUD, implant) are not subject to this aura-related contraindication.

In all cases, any decision regarding contraception in the context of migraines must be made with a healthcare professional.

The diagnosis of a menstrual migraine relies primarily on clinical observation and, more specifically, on a migraine diary kept for at least 3 consecutive cycles. This is a simple, free, yet decisive tool.

For each day, write down:

• The presence or absence of a migraine attack (and its intensity)
• The start and end of your period (Day 1 = first day of menstruation)
• The medications taken and their effectiveness
• Potential trigger factors (stress, sleep, diet, etc.)

If the attacks consistently cluster within the Day -2/Day +3 window for at least 2 out of 3 cycles, the ICHD-3 diagnostic criteria are met. This diary is also the tool your doctor will use to refine their evaluation.

Consult a doctor or a neurologist if:

• Your attacks last more than 48 hours or occur more than 4 times a month
• They are accompanied by an aura (visual disturbances, numbness, speech difficulties)
• Over-the-counter pain relievers do not provide relief or require very frequent intake (risk of medication-overuse headaches)
• The migraines significantly impact your quality of life, your work, or your activities
• You wish to explore medication-based prevention options tailored to your hormonal profile

A menstrual migraine is a real pathology that deserves serious medical care and should not be minimized as "just a simple period pain."

Several micronutrients and plants have been the subject of serious studies in the context of migraines or hormonal imbalances. They can provide complementary support without replacing professional medical advice.

• Magnesium: This is the most well-documented micronutrient for migraine prevention. Clinical studies have shown that supplementation with magnesium (especially in glycinate or bisglycinate forms) can reduce the frequency of attacks, particularly in women with menstrual migraines. Magnesium levels tend to drop before periods. (Mauskop A. et al., Headache 1995; Peikert A. et al., Cephalalgia 1996.)
• Vitamin B2 (riboflavine): Supplementation at 400 mg/day has shown a significant reduction in migraine frequency in randomized controlled trials. Its action works by improving neuronal mitochondrial metabolism. (Schoenen J. et al., Neurology 1998.)
• Coenzyme Q10: Involved in cellular energy production, it has been studied as a preventive agent for migraines with encouraging results across several clinical trials.
• Omega-3 (EPA/DHA): Their anti-inflammatory effect can help modulate the production of pain-inducing prostaglandins. Several studies highlight their value in reducing migraine frequency and intensity.
• Saffron: Recent studies suggest an effect on serotonin modulation and anxiety reduction, which are highly relevant factors in the premenstrual context.

These micronutritional approaches function as basic, long-term prevention: they do not relieve an acute attack instantly but can, over several weeks or months, contribute to reducing their frequency and intensity.

A few lifestyle adjustments can significantly reduce vulnerability to attacks, especially in the days leading up to your period:

• Maintain stable sleep schedules (even on weekends)—irregular sleep patterns are one of the primary identified triggers
• Eat smaller, more frequent meals to avoid reactive hypoglycemia, and stay regularly hydrated
• Reduce dietary triggers within the Day -5/Day +3 window: alcohol, aged cheeses, cured meats (tyramine), and ultra-processed foods
• Manage chronic stress with regular practices: cardiac coherence, yoga, and mindfulness meditation (which has documented efficacy in reducing migraine frequency)
• Keep a cycle diary to anticipate the risk window and adjust your mental and physical workload accordingly
• Engage in moderate and regular sports activities outside of attack periods (intense effort during a flare-up can worsen symptoms)

At MiYé, we build upon a simple conviction: the female body deserves answers tailored to its hormonal reality. That is why our formulations are designed to support hormonal balance as a whole, addressing common micronutritional deficiencies, the inflammation axis, and cycle regulation.

All our formulations are free from phytohormones and suspected endocrine disruptors, and they are developed with active ingredients whose action is fully documented. Because taking care of yourself should never be a guessing game.

Unlike the micronutritional approaches mentioned above, which focus on long-term baseline prevention, certain simple actions can provide relief during the attack itself:

• Hydrate at the very first signs, as dehydration can aggravate pain intensity
• Isolate yourself in a dark and quiet room, as photophobia and phonophobia make any sensory stimulation harder to bear during an attack
• Apply a cold compress to your head or neck: cold has a vasoconstrictive effect that can attenuate throbbing pain. Specially designed cooling caps exist for this purpose, or you can simply use a flexible ice pack wrapped in a clean towel or cloth (never apply ice directly to the skin)

These actions do not replace an acute medical treatment if one is necessary, but they can be combined with medical management or used as a supportive measure while waiting for its effects.

Pregnancy is one of the rare situations where many women who experience migraines notice a significant improvement, or even a complete disappearance of attacks, especially starting from the second trimester. The reason is hormonal: during pregnancy, estrogen levels increase progressively and stably, without the cyclical fluctuations that typically trigger attacks.

In the first trimester, however, hormonal variations are still unstable and may temporarily maintain or worsen migraines. After giving birth, the rapid drop in estrogen levels during the postpartum period can trigger a resurgence of attacks.

This observation firmly confirms the central role of estrogen fluctuations rather than an absolute level of hormones in triggering menstrual migraines.

Perimenopause (generally between the ages of 40 and 52) is frequently a period when hormonal migraines worsen. Cycles become irregular, and estrogen fluctuations intensify and become less predictable, multiplying the windows of vulnerability.

Short cycles follow long cycles, ovulation becomes erratic, and the body can experience multiple hormonal drops per month. For women who already suffered from menstrual migraines, this period is often described as particularly challenging.

At menopause (the permanent cessation of periods), hormones stabilize at a low level, and most women observe a progressive improvement or even a total disappearance of menstrual migraines. Menopause hormone therapy (MHT), when considered, must be discussed with a doctor while taking your migraine profile into account, especially if there is a history of migraines with aura.
