Migraine is roughly three times more common in women than men, and the reason is oestrogen – specifically, the drop in oestrogen rather than the level itself. That is why attacks cluster in the days around a period, why they often improve in pregnancy, and why perimenopause is frequently the worst migraine decade of a woman’s life.
What Is a Menstrual Migraine?
A menstrual migraine occurs in the window from two days before bleeding starts to three days after. It is triggered by the sharp fall in oestrogen that precedes a period. These attacks tend to be longer, more severe, less responsive to treatment and more likely to relapse than migraines at other times of the month – which is why they need a slightly different approach.
Most menstrual migraines occur without aura. If you get visual disturbance or numbness beforehand, that is migraine with aura, which carries a specific safety implication covered below.
Why Does Perimenopause Make It Worse?
In a regular cycle, the oestrogen fall is predictable and happens once a month. In perimenopause, oestrogen swings erratically – sometimes higher than ever, sometimes collapsing – and each fall is a potential trigger. Add the broken sleep, night sweats and stress that characterise this stage, and attacks become both more frequent and harder to predict.
The reassuring part is what follows. Once oestrogen settles at a consistently low level after menopause, migraine improves for most women. The difficult years are the transition, not the destination.
What Triggers an Attack?
| Trigger | What to do about it |
|---|---|
| Oestrogen withdrawal | Track your cycle; consider timed preventive treatment |
| Skipped or delayed meals | Eat regularly – a long gap is one of the most reliable triggers |
| Poor or irregular sleep | Fixed wake time matters more than fixed bedtime |
| Dehydration | Steady fluid through the day, not a large amount at once |
| Alcohol, especially red wine | Common and dose-dependent |
| Stress let-down | Attacks often arrive on the first day off, not during the pressure |
| Bright light, strong smells | Sunglasses, unscented products, screen filters |
Individual food triggers such as chocolate, cheese and citrus are far less consistent than people assume – the craving for chocolate is often an early symptom of the attack rather than its cause. Fix meal timing, sleep and hydration before eliminating foods.
How Is It Treated?
Treatment splits into three parts, and most women only ever try the first.
- Acute treatment. Taken at the very first sign, not once the pain is established. NSAIDs or a triptan, with an anti-sickness medication if nausea prevents absorption. Treating early is the difference between a two-hour and a two-day attack.
- Mini-prophylaxis. For predictable menstrual migraine, a short preventive course started two days before the expected attack and continued through the window. This is prescribed and is genuinely underused.
- Daily prevention. Considered when you have four or more attack days a month. Options include beta blockers, certain antidepressants, topiramate, candesartan and newer CGRP-targeted treatments.
Beware of medication-overuse headache. Taking acute painkillers on more than ten to fifteen days a month can convert episodic migraine into a chronic daily headache. If you are reaching for tablets that often, the answer is prevention, not more painkillers.
What Does Nutrition Contribute?
- Regular meals. Three meals at consistent times, never leaving a gap of more than four to five waking hours. This is the highest-yield change and costs nothing.
- Magnesium. Around 400-600 mg daily of magnesium citrate or glycinate has modest evidence for prevention. Give it three months; loose stools mean reduce the dose.
- Riboflavin (vitamin B2). 400 mg daily has some supportive evidence, though it takes around three months to show effect.
- Steady caffeine. Abrupt withdrawal is a potent trigger. Keep intake consistent and modest rather than swinging.
- Adequate hydration and protein at breakfast, both of which stabilise the blood sugar dips that provoke attacks.
- Check ferritin and vitamin D. Deficiency in either worsens headache burden and is common in Indian women.
The One Safety Point You Must Know
If you have migraine with aura, the combined oral contraceptive pill is generally not recommended, because the combination raises stroke risk. This applies to the pill, patch and vaginal ring containing oestrogen – progestogen-only methods are usually fine. Many women are prescribed the combined pill without ever being asked about aura. If this describes you, raise it with your doctor rather than waiting to be asked. Transdermal HRT is a separate matter and is generally considered suitable, but that decision belongs with your clinician.
When Should You Seek Urgent Help?
- A sudden severe headache reaching peak intensity within a minute
- The worst headache of your life, or one clearly different from your usual pattern
- Headache with fever, neck stiffness, rash or confusion
- New weakness, slurred speech or visual loss
- Aura lasting longer than an hour, or aura on only one side for the first time
- A new headache after the age of 50
Frequently Asked Questions
Will HRT help or worsen my migraines?
It can do either. Steady transdermal delivery through a patch or gel tends to help by smoothing oestrogen fluctuation, while tablets and cyclical regimens more often aggravate it. Discuss the route specifically.
Does migraine mean something is wrong with my brain?
No. Migraine is a disorder of how the brain processes sensory input, not evidence of damage. Imaging is only needed when the pattern changes or red flags appear.
Can I still exercise?
Yes, and regular aerobic exercise reduces attack frequency. Build gradually – sudden intense effort can trigger an attack in some people.
Will my migraines stop after menopause?
For most women they improve substantially once hormone levels stabilise, though it may take a couple of years after the final period.
