Migraine Triggers in Women: Hormones, Thyroid and More-Looking Beyond the Headache

If you’ve ever had a migraine, you already know it isn’t “just a bad headache.”

Migraine is a neurologic disorder that can affect far more than your head. Depending on the person, an attack can include nausea, light and sound sensitivity, visual changes, numbness or tingling, difficulty finding or saying words, dizziness, fatigue, and other neurologic symptoms.

I know because I’ve lived with migraine for most of my life.

But here’s something I’ve learned both personally and professionally:

The factors influencing your migraines may not stay the same throughout your life.

For women especially, migraine patterns can change dramatically during puberty, pregnancy, perimenopause, and menopause. Hormonal fluctuations can matter, but they aren’t the only pieces worth considering.

Thyroid health, nutrient deficiencies, blood sugar, sleep, stress, inflammation, food triggers, medications, neck and musculoskeletal factors, and other health conditions may all influence an individual’s migraine threshold.

That’s why I don’t think the most useful question is always:

“What is causing my migraines?”

Sometimes a better question is:

“What is making my brain more vulnerable to a migraine right now?”

That distinction matters.

I’ve Had Migraines Since I Was a Child

My migraine story didn’t begin with perimenopause.

It didn’t begin with thyroid dysfunction.

It didn’t even begin with my first menstrual cycle.

I started having migraines as a small child.

By the time I was around five or six years old, I had undergone neurologic testing, including an EEG, and had been diagnosed with migraine. Both of my parents also experienced migraines, so I had a strong family history from the beginning.

There were other pieces to my health history, too.

I was born with torticollis, which affected my neck. When I was very young, my mom took me to a chiropractor, and I received gentle care over a period of several months. I believe structural and neck issues may have been one factor in my headache history, although I certainly can’t say they were the cause of my migraines.

Around age six, I was also diagnosed with a dairy intolerance. I don’t remember well enough to say whether eliminating dairy changed my headaches.

What I do remember is needing migraine medication off and on throughout childhood—including having medication available at school.

Migraine was simply part of my life from a very young age.

And then puberty changed the pattern.

When My Periods Started, My Migraines Changed

Once I started menstruating, a hormonal pattern became much more obvious.

Throughout my teens and 20s and into my early 30s, I experienced frequent headaches, but my migraines were particularly likely to occur the day before my period.

That timing wasn’t random.

Changes in estrogen around menstruation are a well-recognized migraine trigger for some women. The relationship between estrogen and migraine is complex, but fluctuations—particularly a drop in estrogen—can influence migraine susceptibility.

That doesn’t mean “estrogen causes migraines.”

It means the changing hormonal environment may affect the threshold at which a susceptible brain develops a migraine attack.

And I was clearly susceptible long before I ever had a menstrual cycle.

That’s an important distinction.

Think of Migraine Like a Threshold

One of the most useful ways to understand migraine is to think about a migraine threshold.

Imagine a bucket.

Genetics may already put some water in your bucket. Then you add hormonal fluctuations. Poor sleep adds a little more. Stress adds more. Skipping meals, dehydration, nutrient deficiencies, certain foods, illness, neck tension, or other individual triggers may add to it too.

One factor by itself might not be enough to overflow the bucket.

But once enough factors accumulate, you cross your migraine threshold.

The attack is the overflow.

This helps explain why something that seemed to trigger a migraine one week may not trigger one the next.

It also helps explain why migraine patterns can change so dramatically throughout a woman’s life.

The bucket itself isn’t necessarily the same at 15, 35, 45, and 55.

Migraine Can Be Much More Than Head Pain

Before my 30s, I typically knew a migraine was coming because I would feel pain around my right eye. I would develop light sensitivity and nausea. There was a familiar feeling that told me, Here it comes.

But in my early to mid-30s, my migraine symptoms began changing.

I started experiencing more frightening neurologic symptoms along with some attacks.

My legs could feel shaky or weak. I could have numbness. I could become extremely nauseated and sensitive to light.

At other times, I knew exactly which word I wanted to say, but a completely different word would come out of my mouth.

I’ve had one hand and half of my face go numb.

I’ve had spots in my vision so that I cannot see.

I’ve experienced brain fog and clumsiness surrounding migraines as well.

These symptoms are part of why it’s so important to understand that migraine—especially migraine with aura—is a neurologic condition, not simply severe head pain.

A very important safety note

Neurologic symptoms should never automatically be blamed on migraine.

New weakness, numbness, difficulty speaking, confusion, vision changes, or other new or significantly different neurologic symptoms can overlap with symptoms of stroke and other serious conditions.

New, sudden, severe, or unusual neurologic symptoms require appropriate medical evaluation.

Even if you’ve had migraine with aura before, a significant change from your usual pattern deserves attention.

Then My Health Started Changing Too

Here’s where my story becomes more complicated—and, I think, more useful.

During my 30s, I wasn’t only experiencing changes in migraine.

I was also developing increasing joint pain. By my later 30s, my menstrual cycles were becoming irregular. Eventually, I entered what I now recognize as a much more obvious perimenopausal transition.

Looking backward, I also had symptoms that make me wonder whether thyroid dysfunction and Hashimoto’s may have been developing during this period.

But I want to be very clear about that:

I wasn’t appropriately tested for thyroid antibodies and a more complete picture of thyroid function at that time, so I cannot say that I had Hashimoto’s then (although, looking back, I had most of the symptoms).

Because I wasn’t tested, I can only say that I had symptoms years before I was eventually diagnosed that, in hindsight, made me wish someone had taken a deeper look at my thyroid.

That’s one reason “Test. Don’t guess.” has become such an important part of how I practice today.

It’s easy to connect dots retrospectively. It’s much harder—and much more important—to gather enough information to determine whether those dots actually belong together.

Perimenopause Changed My Migraine Pattern Again

Perimenopause can be a time of migraine triggers for may women. By the time I reached early perimenopause, another pattern had emerged.

Instead of primarily experiencing migraine right before my period, I began having attacks around two hormonally significant points in my cycle:

• Around ovulation
• The day before menstruation

That pattern made sense physiologically because both times involve significant changes in reproductive hormones.

Perimenopause can make those fluctuations even less predictable.

Ovulation may become inconsistent. Estrogen can fluctuate substantially. Progesterone exposure may change as ovulation becomes less predictable.

For a woman whose brain is already susceptible to migraine, that changing hormonal environment may matter.

But here’s where I want women to be careful.

If migraines become worse during perimenopause, it’s tempting to conclude:

“My hormones are the problem.”

Sometimes hormones are an important piece.

But they may not be the only piece.

And my own story eventually taught me exactly that.

What Else Can Influence Your Migraine Threshold?

During that earlier perimenopausal period, I started paying more attention to the things that seemed to influence my migraines.

I used acupuncture. I took higher doses of magnesium glycinate and riboflavin (vitamin B2). I worked on my gut health. I had also gone gluten-free around age 38.

Over time, my migraines became much more manageable again. For quite a while, they were mostly limited to those predictable hormonal windows around ovulation and right before my period.

Can I tell you exactly which intervention made the difference?

No. (Although I can say that going gluten-free yielded a HUGE improvement for me.)

And I think that’s an important part of my story.

It would be easy to look backward and say, “I did this, and therefore this fixed my migraines.”

The human body rarely gives us such tidy answers.

What I can say is that several factors that may influence migraine susceptibility were changing at the same time.

And that brings us to an important question:

What should we look at when someone’s migraine pattern changes?

1. Hormonal Fluctuations

Hormones deserve a prominent place in any discussion about migraine triggers in women.

Many women notice migraine patterns around:

• Menstruation
• Ovulation
• Pregnancy and postpartum
• Perimenopause
• Menopause
• Starting or changing hormone therapy

Estrogen appears to be particularly important.

It isn’t necessarily having “too much” or “too little” estrogen that matters. Changes and fluctuations in estrogen may influence migraine susceptibility, especially in someone already prone to migraine.

That’s one reason perimenopause can be such a challenging time.

Hormones don’t simply decline in a nice, predictable straight line.

Estrogen can fluctuate substantially. Ovulation can become less consistent. Progesterone exposure can change. Menstrual cycles may shorten, lengthen, become heavier, or become unpredictable.

For someone with hormonally sensitive migraines, those changes can alter a pattern that may have been fairly predictable for years.

My migraines changed again in later perimenopause

I did relatively well through much of my 40s.

Then, in my later 40s, my headaches and migraines became much worse.

Eventually, I was having headaches or migraines almost daily.

By that point, however, hormones weren’t the only thing changing.

My energy was poor. My joint pain was worse. And eventually I was diagnosed with hypothyroidism.

That became another important piece of my puzzle.

2. Thyroid Health

Migraine and thyroid disorders can occur together, and research has found associations between migraine and hypothyroidism.

That does not mean hypothyroidism causes every migraine.

It also doesn’t mean treating someone’s thyroid will automatically make migraines disappear.

But if a woman with migraines also has symptoms that raise questions about thyroid function—fatigue, cold intolerance, constipation, hair changes, dry skin, menstrual changes, unexplained weight changes, or other compatible symptoms—it may be reasonable to make sure her thyroid has been appropriately evaluated.

My experience made this particularly meaningful to me.

When I was finally diagnosed with hypothyroidism and started prescription thyroid medication through my prescribing clinician, my headaches and migraines improved substantially.

At one point, however, my thyroid medication was discontinued for a short period.

My energy dropped.

My joint pain increased.

And my headaches and migraines worsened again.

Once I was eventually able to get back on an appropriate thyroid treatment plan with my prescribing clinician, I improved again.

That experience is one of the reasons I’m so passionate about looking beyond TSH alone when the clinical picture warrants it.

TSH is important.

But depending on the situation, understanding thyroid physiology may involve looking at the broader clinical picture and additional thyroid testing.

The goal isn’t to blame every migraine on the thyroid.

It’s to avoid overlooking thyroid dysfunction in a woman who has other reasons for us to investigate it.

3. Perimenopause May Change More Than Your Period

After thyroid treatment, I did much better for about a year.

Then my migraines began worsening again.

This time, my thyroid wasn’t the only question.

I was also experiencing other symptoms consistent with the menopause transition, including mood changes and vaginal dryness.

My prescribing clinician and I discussed the possibility that changing reproductive hormones were contributing to the bigger picture. We ultimately decided that menopausal hormone therapy was appropriate for me.

After I started hormone therapy, my migraines improved again.

That is my personal experience, not a recommendation that every woman with migraine should start hormone therapy.

Hormone therapy and migraine require individualized medical decision-making. Migraine type, aura history, age, cardiovascular and stroke risk factors, personal and family medical history, route of estrogen administration, dose, and other factors may all matter.

If hormone therapy is being considered, that conversation belongs with an appropriately qualified prescribing clinician.

What my experience illustrates is something different:

When your migraine pattern changes, ask what else changed.

Did your periods change?

Did your sleep change?

Did your stress level change?

Did you begin skipping meals?

Did your thyroid function change?

Did you start or stop a medication?

Are you entering perimenopause?

Did your iron status change because your periods became heavier?

Sometimes the timeline gives us clues that a single migraine diary never could.

4. Magnesium, Riboflavin and Nutrient Status

Nutrition doesn’t get nearly enough attention in conversations about migraine.

Two nutrients with evidence supporting their use in migraine prevention are magnesium and riboflavin, or vitamin B2.

I have personally used both.

But there’s a larger lesson here than simply buying magnesium and B2.

I don’t want women walking away from this article thinking:

“Great. I just need another supplement.”

That’s still guessing.

Depending on someone’s history, I may also want to understand her overall nutritional status.

For example, does she have:

• A highly restrictive diet?
• Heavy menstrual bleeding?
• Digestive problems affecting nutrient intake or absorption?
• Iron deficiency?
• Low vitamin B12 or folate?
• Poor appetite?
• A history of bariatric surgery?
• Medications that may affect nutrient status?

The goal isn’t to order every nutrient test available because someone has migraines.

It’s to use her history to decide which questions actually make sense to ask.

Test. Don’t guess.

5. Blood Sugar and Skipping Meals

Have you ever gotten busy, skipped lunch, and then realized your head was starting to hurt?

For some people with migraine, fasting or missing meals can be a trigger.

This doesn’t necessarily mean they have diabetes or even insulin resistance.

The brain needs a steady supply of energy, and significant changes in meal timing or energy availability can be problematic for some migraine-prone people.

This is why I often want to know more than:

“What do you eat?”

I want to know:

When do you eat?

Are you drinking coffee for breakfast and not eating until noon?

Are you eating very little protein?

Do you crash in the afternoon?

Do you get shaky, irritable, nauseated, or headachy if you go too long without food?

Are migraines more likely on days when meals are delayed?

Patterns matter.

Sometimes a symptom diary that includes food, sleep, menstrual cycle timing, stress, and headache symptoms reveals relationships that aren’t obvious when we look at migraine in isolation.

6. Sleep and Stress Can Lower the Threshold

Sleep and migraine have a complicated relationship.

Poor sleep may increase migraine susceptibility, while migraine itself can disrupt sleep.

Stress can work similarly.

This doesn’t mean migraines are “just stress.”

They aren’t.

Telling someone with a neurologic disorder to simply relax is neither accurate nor particularly useful.

But chronic stress can affect sleep, muscle tension, eating patterns, blood sugar regulation, pain processing, and the autonomic nervous system.

That’s why I don’t ignore stress simply because it isn’t the whole explanation.

The question isn’t:

“Is this physical or stress-related?”

Stress is physical.

The better question is whether stress and inadequate recovery are adding more water to an already-full migraine bucket.

7. What About Gut Health and Food Triggers?

This is an area where we need nuance.

I went gluten-free around age 38 and felt that my overall health—and  my migraine pattern—improved.

I was later diagnosed with Hashimoto’s, which naturally makes me wonder whether gluten was relevant to my health at that earlier stage.

But I wasn’t appropriately tested for Hashimoto’s then.

So I can’t go backward and prove that connection.

And I certainly wouldn’t tell every woman with migraine to eliminate gluten.

Food triggers are highly individual.

For someone with celiac disease, gluten must be avoided for reasons that extend far beyond migraine. Other people may identify specific foods that reliably trigger attacks. Still others can unnecessarily restrict their diets while trying to find the one food responsible for their symptoms.

Gut health is also an emerging area of migraine research, including interest in the gut-brain axis and the relationship between gastrointestinal disorders and migraine.

But “heal your gut and your migraines will disappear” is far too simplistic.

If a woman has migraine and chronic bloating, reflux, constipation, diarrhea, abdominal pain, known food reactions, or other digestive symptoms, I think those symptoms deserve their own appropriate evaluation.

Not because every gut problem causes migraine.

Because the body doesn’t operate in separate compartments.

8. Don’t Forget the Neck and Musculoskeletal System

My own history includes another piece I can’t ignore.

I was born with torticollis and have dealt with neck and structural issues throughout my life.

That does not mean my neck caused a neurologic disorder that clearly also has a strong genetic and hormonal component.

But neck pain and migraine frequently overlap, and some people notice that neck tension or musculoskeletal problems accompany or influence their headaches.

There is also an important chicken-or-the-egg problem here:

Neck pain can sometimes be part of the migraine attack itself.

In other cases, musculoskeletal problems may contribute to headache symptoms.

That’s why neck pain shouldn’t automatically be assumed to be either the cause or merely a consequence of migraine.

It deserves to be evaluated in context.

Acupuncture Has Been an Important Tool for Me

Acupuncture has also played an important role in my own migraine management.

When I can treat myself with acupuncture during a severe migraine, I often find that I move through the painful phase more quickly.

One of the biggest differences I’ve personally noticed is afterward.

Migraine doesn’t necessarily end when the headache stops.

The postdrome, sometimes called the “migraine hangover,” can last hours or even longer. People may experience fatigue, difficulty concentrating, mood changes, weakness, or simply feel unlike themselves.

My postdrome often manifests as fatigue and clumsiness.

When acupuncture works well for me during an attack, I frequently don’t experience as much of that next-day migraine hangover.

Occasionally I still do.

That’s an important distinction because acupuncture isn’t a guaranteed migraine cure.

It is an evidence-informed complementary therapy that may be helpful for migraine prevention and symptom management for some people.

For me, it has become one tool in a much larger toolbox.

Stop Looking for One Universal Migraine Trigger

If there’s one thing my migraine history has taught me, it’s this:

There was never one thing to fix.

I had migraines as a child, long before menstruation, thyroid dysfunction, or perimenopause entered the picture.

I also have a strong family history of migraine.

That tells me there was an underlying susceptibility from the beginning.

But the pattern changed.

Puberty changed it.

My menstrual cycle affected it.

Perimenopause changed it again.

Thyroid dysfunction appears to have been an important part of my later health picture.

Sleep, stress, nutrition and musculoskeletal factors can matter.

And different interventions have helped me at different stages of my life.

That’s why I don’t think the goal should always be to identify the one root cause of migraine.

A better goal may be to understand the factors affecting your migraine threshold.

Start With the Timeline

If your migraines are changing, one of the most useful things you can do is build a timeline.

Ask yourself:

• When did my migraines begin?
• Do I have a family history?
• Did they change when I started menstruating?
• Do they occur around ovulation or menstruation?
• Have they changed during perimenopause?
• What happens when I don’t sleep well?
• Do skipped meals matter?
• Is neck pain associated with my attacks?
• Did my migraines change after starting or stopping a medication?
• Are there digestive symptoms or known food triggers?
• Do I have symptoms that warrant evaluation of thyroid function, iron status, or other health concerns?
• What happens in the 24–48 hours before my migraine—not just during it?

That last question can be particularly revealing.

Sometimes what we think is a trigger may actually be an early part of the migraine process itself.

The more carefully you understand your pattern, the better questions you can bring to your healthcare team.

You Don’t Have to Explain Everything With One Diagnosis

I spent much of my life knowing I had migraine.

What changed was my understanding of everything happening around the migraine.

My migraines didn’t begin because of perimenopause.

They didn’t begin because of my thyroid.

And I can’t claim that changing my diet, taking magnesium, using acupuncture, treating my thyroid, or starting hormone therapy “fixed” the root cause.

My history is more complicated than that.

Most real health stories are.

What I learned was to stop looking at each symptom in isolation.

Migraine was one piece.

My menstrual cycle was another.

My thyroid was another.

My joint pain, energy, sleep, nutrition, gut health, stress and changing hormones were additional pieces.

Sometimes those pieces were related.

Sometimes they may simply have existed at the same time.

The job is to figure out which connections are meaningful.

That’s what I mean when I talk about connecting the dots.

Not assuming everything is connected.

Investigating whether it is.

And sometimes that shift—from chasing one explanation to asking better questions—is where we finally begin to understand what our bodies have been trying to tell us.

Ready to Stop Guessing?

If your migraines have changed and you’re also struggling with fatigue, brain fog, digestive symptoms, thyroid concerns, perimenopause symptoms, poor sleep, or other unexplained changes, it may be worth looking at the bigger picture.

Functional medicine doesn’t replace appropriate neurologic evaluation or migraine treatment.

It can help us ask whether there are additional pieces of your health that deserve attention.

At Functional Health KC, I work with women to review their health history, symptoms, previous laboratory testing, nutrition, lifestyle, and other factors to determine where deeper investigation may be appropriate.

You don’t need someone to promise you one magical root cause.

You need someone willing to listen to the whole story.

FAQ

Can perimenopause make migraines worse?

Yes, migraine patterns can change during perimenopause. Fluctuating estrogen and changing ovulatory patterns may influence migraine susceptibility in some women. Some women experience worsening migraines, while others may experience different patterns. A significant change in headaches should still be discussed with an appropriate healthcare professional rather than automatically attributed to hormones.

Can thyroid problems cause migraines?

Thyroid disorders and migraine have been associated in research, but that doesn’t mean thyroid dysfunction is the cause of every migraine. If someone with migraines also has symptoms or history suggesting thyroid dysfunction, appropriate thyroid evaluation may be worthwhile.

What vitamins or supplements may help prevent migraines?

Magnesium and riboflavin (vitamin B2) are among the nutritional supplements with evidence supporting migraine prevention in some people. Appropriate products and doses should be individualized, particularly when other medical conditions or medications are involved.

Can migraines cause trouble finding words or numbness?

Migraine with aura can include neurologic symptoms such as visual changes, sensory symptoms, and speech or language disturbances. However, similar symptoms can occur with serious neurologic conditions. New, sudden, severe, or significantly different neurologic symptoms require prompt medical evaluation.

Can acupuncture help migraines?

Research suggests acupuncture may be useful as a complementary option for migraine prevention for some people. Response varies, and acupuncture should be considered one potential component of an individualized migraine management plan rather than a guaranteed treatment.
