What it is
Hormonal migraines typically hit just before a period or during the erratic estrogen drops of perimenopause, often with light sensitivity and nausea.
What's causing it
Estradiol withdrawal
It's the rate of the drop that triggers migraine, which is why perimenopause — with its wild swings — is the worst window for many women.
Low magnesium
One of the best-evidenced nutritional factors in migraine prevention.
Poor sleep and skipped meals
Classic amplifiers.
Nutrients commonly involved
What actually helps
- Steady, continuous estradiol delivery rather than dosing that creates peaks and drops
- Magnesium and riboflavin as preventives
- Consistent sleep and meal timing
- Discussing migraine with aura with your prescriber, as it affects hormone therapy choices
