I Have Severe Headaches Every Period: Hormonal Headache?

Period-Related Headaches: The Disharmony Between the Brain and Hormones is to Blame

Many women suffer from headaches that occur around the same time each month. They often dismiss them as simple fatigue or stress, taking a painkiller or two, but for some, the pain is so severe that even those don't provide relief.

Headaches that show a clear pattern aligned with the menstrual cycle are called 'menstrual migraines' or 'hormonal headaches'. These are not just simple pain issues, but can be a signal from our body's intricate hormonal system.

The prime suspect is the female hormone 'estrogen'. Estrogen levels, which peak during ovulation, drop sharply like a rollercoaster just before menstruation. This very 'estrogen cliff' triggers headaches. Estrogen plays a crucial role in regulating the secretion of 'serotonin,' often called the happiness hormone in the brain. When estrogen levels drop, serotonin concentrations also decrease.

Serotonin is a neurotransmitter that plays a key role in regulating blood vessel constriction and dilation, as well as controlling pain. When serotonin levels are low, brain blood vessels are more prone to abnormal dilation, and sensitivity to pain becomes extremely heightened. This is why the head throbs particularly intensely just before menstruation, and why patients with 'hormonal migraines' become sensitive to external stimuli like light and sound.

This situation is like 'a dam's water level control system breaking down'. Normally, the dam (brain) maintains an appropriate water level (serotonin) and stably manages pain signals, but when the core control system, estrogen, falters, even a small rain (stimulus) can easily lead to a flood (headache).

There's another accomplice here: 'magnesium'. Estrogen is also involved in maintaining magnesium levels in the body, so when estrogen levels drop, magnesium absorption decreases, and its excretion through urine increases. Indeed, studies have shown that women suffering from menstrual migraines have significantly lower intracellular magnesium levels in red blood cells than women who do not.

Magnesium is a vital mineral, often called a 'natural tranquilizer,' as it calms nerve excitability and relaxes muscles. This is also why headaches are listed as one of the symptoms of magnesium deficiency. When magnesium is deficient, brain nerves become easily excited even by minor stimuli, which further exacerbates headaches.

Ultimately, the cause of period headaches is a complex result created by two factors—'serotonin depletion' and 'magnesium deficiency'—acting simultaneously on the trigger of 'estrogen plummeting'. Estrogen plunge begins 3-5 days before menstruation → Increased sensitivity due to serotonin depletion 1-2 days later → Worsening magnesium deficiency just before menstruation begins → Severe PMS headache occurs.

So, what can we do to break this vicious cycle of headaches? Instead of relying solely on painkillers for menstrual pain relief, we need to shift our perspective towards stabilizing our body's hormonal balance.
