When migraine changes in your forties

Something starts to change in your early forties. The migraine you have managed for years, more or less, stops behaving. Attacks turn up at odd points in the month rather than the day before your period. They last longer. The medicine that used to work now takes the edge off and no more. If that sounds familiar, you are not imagining it and it is not simply stress.

What perimenopause actually does to migraine

Perimenopause is the run-up to menopause, and it usually begins in the early to mid forties. The average age of menopause in the UK is 51, so this stage can run for years rather than months.

The important detail is that oestrogen does not glide gently downwards. It swings. A fall in oestrogen is a well-recognised migraine trigger, which is why so many women have attacks in the days around a period. During perimenopause those falls happen more often and far less predictably.

Two things are important to follow from this. Cycles tend to shorten, so menstrual attacks come round more frequently. And hot flushes and night sweats break up sleep, which is a trigger in its own right. More attacks, less recovery between them. It is also possible to develop migraine for the first time at this stage of life, which surprises people who have never had a bad headache before.

Why it gets missed so often

Migraine and perimenopause peak in the same decade, and they share a good deal of overlapping ground. Tiredness, disturbed sleep, low mood, difficulty concentrating: all of it belongs to both. When symptoms could plausibly be either, they tend to get attributed to one thing in passing and treated properly by nobody.

There is a treatment gap here too. When women attending a specialist menopause clinic were surveyed, 42% were found to have migraine, and most were relying on medication not designed for it. A third used paracetamol alone. A fifth were treating attacks with codeine-containing painkillers, which is a poor choice for migraine and carries a real risk of medication overuse headache. That was a specialist clinic population rather than the general public, so treat it as information about undertreatment rather than a prevalence figure. It matches what I see in clinic too.

What tends to help

• Check whether your attacks still follow your cycle. Many women assume the hormonal link has broken because the timing has gone strange. Often the link is still there, it has simply sped up. A few months of simple records usually shows it.
• Get the acute treatment right. If paracetamol or a codeine-based painkiller is all you have, that is worth another trip to your GP. Keep acute medication to no more than two days a week where you can.
• Protect sleep deliberately. Night sweats fragment it and fragmented sleep feeds attacks. Room temperature, bedding and timing are unglamorous but they can make a huge difference.
• If HRT is being discussed, ask about the route. Transdermal oestrogen, meaning patches, gel or spray, gives steadier hormone levels than tablets and is generally preferred where migraine is present. Worth knowing: migraine with aura rules out the combined oral contraceptive pill, but it does not rule out HRT, which uses a different form of oestrogen at a much lower dose.

Prescribing decisions belong with your GP or menopause specialist, not with an osteopath. What we can do is help you walk into that appointment with a clear picture of your pattern, so the conversation starts from evidence rather than a vague sense that things have got worse.

The part that is not about hormones

Hormonal change raises the baseline but it rarely acts alone. Neck and shoulder tension, jaw clenching, disturbed sleep and long stretches of stress all sit on top of that raised baseline, and unlike your oestrogen levels, several of them can be assessed and treated directly. That is usually where the practical gains are.

It is worth noting that migraine does often settle after natural menopause, though not straight away, since the ovaries can keep producing variable amounts of oestrogen for some years. Surgical menopause, where the ovaries are removed, can make migraine worse rather than better. Either way, waiting it out is not much of a plan for a stage of life that can last the better part of a decade.

If your migraine has changed and nobody has looked at the whole picture, a full assessment is a reasonable next step. You are welcome to book an appointment or get in touch.
