For women, men, and children who suffer from migraine disease, Migraine Heroes is your go-to resource for understanding, managing, and overcoming migraine attacks.

We cover all types of migraines and related headaches, including primary and secondary migraines, chronic migraines, and cluster migraines. We dive deep into the complexities of migraine with aura and migraine without aura, as well as rarer forms like hemiplegic migraine, retinal migraine, and acephalgic migraine (silent migraine). Our discussions also extend to cervicogenic headaches, ice pick headaches, and pressure headaches, which often mimic migraine or contribute to overall migraine burden.

Transcript

[00:00]

What if one of the reasons your migraine keeps showing up has nothing to do with stress,

[00:04]

hormones or food, and everything to do with your blood pressure being a little too low

[00:10]

for your brain's needs?

[00:14]

Welcome to Migraine Heroes, a podcast for people living with chronic migraines with years of pain,

[00:20]

misunderstanding and lack of answers. I'm Diane Ducarme. I've helped more than a thousand people

[00:26]

reduce the burden of migraines and feel more in control. My mission in life? To help a million

[00:33]

people. Each episode brings you grounded insight into what your body might be asking for and what

[00:39]

can truly help. Just to keep you fully supported, this podcast is educational. For diagnosis or

[00:47]

medication, always work with your doctor. Now, take a breath and let's dive in.

[00:54]

In this episode, you will learn why low blood pressure can create the perfect conditions for

[00:59]

migraine attack, even when your blood pressure is considered normal. How to recognize the subtle

[01:04]

signs that poor circulation may be contributing to your headaches, fatigue, dizziness and brain

[01:10]

fog. And one simple at-home way to estimate your monthly blood balance. Stay with me till the end

[01:17]

of this episode, because at the end of this episode, you will receive an at-home way to

[01:22]

to estimate your monthly blood balance. If you live with migraines, you may know the feeling.

[01:28]

So you stand up and suddenly you feel lightheaded. You skip a meal and your headache begins

[01:34]

creeping in. A hot shower leaves you completely exhausted. You oftentimes feel cold, tired,

[01:39]

foggy and somehow your body never seems to have enough energy. Yet, every blood test comes back

[01:46]

normal. And it can feel frustrating and super confusing. And many people spend years looking

[01:54]

at hormones, food, stress, sleep, while overlooking one important factor, your blood flow.

[02:00]

So what is low blood pressure? Blood pressure can also be called hypotension and is generally

[02:06]

defined as blood pressure below 90 over 60. So 90 over 60 millimeters of mercury. However,

[02:14]

the real issue is not always the number itself. Some people naturally have lower blood pressure

[02:21]

and feel perfectly fine and healthy. And others experience symptoms because their brain and

[02:25]

tissues are not receiving consistent blood flow throughout the day. And that distinction is

[02:31]

absolutely critical. So why does blood flow matter for migraines? The brain represents

[02:37]

only about 2% of your body weight, yet it's going to consume roughly 20% of your body's

[02:43]

oxygen supply. And because of its enormous energy demand, the brain is extremely sensitive to

[02:49]

changes in circulation. Researchers have long suspected that vascular reticulation plays a

[02:55]

role in migraine development. And although migraine is now recognized primarily as a neurological

[03:00]

disorder, blood vessel function remains a super important part of the story. Migraine involves

[03:05]

interactions among nerves, blood vessels, inflammation and signaling molecules. And so

[03:10]

when blood pressure drops, the body must compensate to maintain adequate blood flow

[03:15]

to the brain. In susceptible individuals, these compensatory mechanisms may contribute to activation

[03:21]

of migraine pathways. So what does the research show or say? The relationship between blood

[03:27]

pressure and migraine is fairly complex. Several population studies have observed that people

[03:32]

suffering from headaches and migraines often have lower systolic blood pressure compared to those

[03:37]

without headaches. And some studies have found an inverse relationship, meaning that low blood

[03:42]

pressure was associated with a higher likelihood of headaches. So for example, research discussed

[03:48]

in the Journal of Clinical Medicine found that low systolic blood pressure was a significant

[03:53]

predictor of headache occurrence in adolescents. And psychological factors also play a role,

[03:58]

suggesting that migraine is influenced by both physiological and neurological mechanisms.

[04:04]

At the same time, researchers emphasize that migraine and blood pressure have a multifactorial

[04:09]

relationship. Not everyone with low blood pressure develops migraines, and not everyone with migraines

[04:15]

has low blood pressure. So there are some common symptoms that may suggest a circulation component.

[04:21]

You may want to explore the possibility of low blood pressure contributing to migraine if you

[04:26]

regularly experience dizziness when standing up, cold hands and feet, fatigue that worsens

[04:31]

throughout the day, brain fog, a certain exercise intolerance, migraines triggered by heat,

[04:37]

migraines after skipping meals. These clues suggest that your nervous system may be struggling

[04:42]

to maintain a stable circulation. Now another important piece of the puzzle involves the

[04:48]

autonomic nervous system. So the system automatically regulates your heart rate,

[04:52]

your blood vessel tone, and your blood pressure. And many migraine sufferers show signs of autonomic

[04:57]

dysfunction. Their bodies may have difficulty adapting quickly to changes in posture,

[05:02]

temperature, stress, or hydration status. And as a result, seemingly small changes can create

[05:07]

fluctuations in blood flow that increase migraine vulnerability. Emerging research continues to

[05:13]

explore how vascular regulation, autonomic balance, and migraine are interconnected.

[05:18]

Because they truly are. The key takeaway is that low blood pressure may not be the sole cause of

[05:23]

migraines. However, for some people, it may act as a significant trigger, an amplifier, definitely

[05:30]

a missing piece of the puzzle. If you know me well, you know that my journey into health and

[05:36]

ultimately into migraine healers began with a skiing accident. When I was 17 years old,

[05:41]

I lost nearly half of my blood, literally. And at the time, I broke my femur. And at the time,

[05:46]

because of blood contamination issues at the national level in France and resulting shortages

[05:52]

in the blood banks, I could not be transfused. And my body had to rebuild what it had lost,

[05:58]

meaning half of it, on its own. Recovery was slow, slow, slow, slow. Much slower than I expected.

[06:06]

And I remember profound fatigue, dizziness, inability to do what I had previously taken for

[06:11]

granted. Some of my blood pressure readings in those first weeks were astonishingly low. But

[06:17]

later in life, they still were low. And looking back, that experience gave me an enormous empathy

[06:22]

for what traditional Chinese medicine would call blood deficiency or depletion of vital nourishment.

[06:29]

When I started to take care of people who were suffering from migraine disease, it made me realize

[06:34]

something important about women. Over the course of her lifetime, the average woman will lose

[06:39]

somewhere between 23 and 28 liters of blood through menstruation alone. That's almost half her weight.

[06:46]

For some women, it can be considerably more through heavy menstruation, copper IUDs,

[06:51]

difficult childbirth, surgery, blood donation, or other causes of blood loss. And when you've

[06:56]

personally experienced what it feels like to run on an empty tank, you develop a deep respect for

[07:02]

the role of blood, but also the pain that it comes when it comes to energy and resilience

[07:07]

and concentration and emotional well-being. Blood pressure is just one reflection of that reality.

[07:13]

And in many ways, that accident changed the course of my life. It led me to discover

[07:19]

traditional Chinese medicine 12 years later. It taught me what it feels like when your body

[07:24]

lacks resources, it needs to thrive. And it plants a seed that would eventually become my life's work.

[07:30]

The hope of helping others receive the same care, understanding, and support that I received during

[07:35]

my own recovery 12 years later. And I'm really conscious my story isn't classic.

[07:40]

Sometimes I get the comment, oh, it'd be easier if you had migraines yourself. My sister had

[07:44]

migraines. I think migraines are so, so, so plural. What it gave me was the ability to see

[07:50]

so many different root causes without bias, without judgment, not trying to solve everyone

[07:58]

the way I was, but taking everyone the way they were. And that is what makes Migraine Heroes

[08:04]

possible today, literally, is radical acceptance of the plurality and the differences that you all

[08:11]

have, your unique patterns and profile. When you go in the app today, it asks you a couple of

[08:16]

questions and immediately gives you insight into what could be, what do we see as one of the root

[08:23]

cause, the more dominant root cause of your migraines. And it comes from that massive

[08:27]

empathy, that massive gratitude of, for 12 years, feeling unwell, feeling ill-equipped, feeling tired,

[08:34]

napping from 2pm to 8am the next day, having just a body functioning in part, and the joy that

[08:41]

it comes when I get to make that gift to someone. And that's what's driving us fully. And I hope

[08:48]

that you can feel the integrity of us as a small team, the integrity of genuinely coming into your

[08:55]

life and making it flourish, giving you back your own self-transform. Now, from a traditional

[09:04]

transmedicine perspective, migraines are not viewed as an isolated set of events happening

[09:09]

only in your head. They're understood as signals that the body's internal flow has become disrupted.

[09:16]

And one concept particularly relevant here is that blood volume deficiency. That's a concept

[09:23]

a little bit, little existent in the West, very prevalent in the East, and coupled with chi

[09:29]

deficiency, just the idea of movement. So chi can be thought as the body's vital energy, the force

[09:35]

that drives circulation, warmth, vitality and function, and blood nourishing and anchoring that energy.

[09:40]

When blood is insufficient, the brain may not receive adequate nourishment. Traditional

[09:46]

transmedicine is going to describe this state as the body lacking enough resources to fully supply

[09:52]

the head and the senses. Interestingly, many people with low blood pressure fit this pattern

[09:57]

remarkably well. They will often report fatigue, you know. It's interesting, you know, when I was

[10:02]

presenting the app to, they were saying, oh, fatigue, everyone feels fatigue. I'm like, no, no, no, I'm not

[10:06]

talking fatigue. I'm talking about fatigue like I'm going to bash my head through the wall because

[10:12]

I'm so tired. I have exceeded the fatigue anything. I'm beyond the world of fatigue. They may experience

[10:19]

dizziness. Okay, this is something I was experiencing a lot. Like, you know, I'd stand up

[10:23]

too fast and I'd feel dizzy. I'd have to sit on my bed. Feeling cold definitely had that for me a lot,

[10:29]

like the hands, the feet, pale complexion, absolutely. Weak digestion, for sure. You know, if you don't

[10:34]

have enough blood, you can't digest properly. Brain fog, poor stamina. And in traditional transmedicine,

[10:39]

the head is considered the sea of the marrow, a place that requires continuous nourishment. And

[10:44]

when the body's resources are depleted, symptoms such as headaches, dizziness, and mental fatigue,

[10:49]

they may emerge, they will emerge. But the way your brain asks for these things is very sensible.

[10:55]

And I think if you take anything away from everything that I'm saying, and from all of these

[11:00]

podcasts, is you can trust your body. You can fundamentally trust it, even though you feel

[11:06]

broken inside and outside, and you feel you're not making any sense. I can promise you from the work

[11:12]

that I've done, you always do. You always do. It's just sometimes hard to see the forest from the

[11:19]

trees. But you can fundamentally trust your body. So if your body's in pain and asking for help,

[11:26]

try to listen. There's an ancient saying that teaches, when the river runs shallow, the fields

[11:33]

cannot be nourished. And the body works the same way as nature. If your circulation is insufficient,

[11:40]

the tissues at the farthest reaches, including your brain, may struggle to receive what they need.

[11:46]

And as you can feel, this is really close to my heart, because this is a root cause that I can

[11:51]

really relate to quite fundamentally. Now, sometimes it's not just about adding blood, there's

[11:56]

a lot more complexity and sophistication to things. But understanding, I fundamentally believe,

[12:03]

is the first step towards feeling completely better and completely yourself. So from this

[12:09]

perspective, migraines may seem sometimes just represent your body's way of saying,

[12:13]

I do not have enough reserves to keep going at this pace. That message, just that simple message,

[12:19]

it deserves attention. Recently, a woman that, you know, she was making progress inside the app, but

[12:25]

quite slowly. She was slower than anticipated because she was so young. I was expecting her

[12:31]

to be decently fast. And I realized that through her copper IUD, she was bleeding a lot. And when

[12:36]

asking her, she wasn't too much aware of how much she was bleeding. And I encouraged her to calculate,

[12:42]

and it turns out, she was bleeding 11 times what she was supposed to bleed. And so basically, I was

[12:47]

filling a leaky bucket. So here's my advice for today. If you menstruate, I'd like you to take a

[12:53]

moment this month to become curious about your blood loss, rather than simply accepting it as

[12:58]

normal. Okay? Menstrual blood loss is often estimated at around 30 to 40 milliliters per

[13:04]

cycle, and losses above 80 milliliters are generally considered heavy menstrual bleeding.

[13:09]

So here, we're talking 1 to 1.4 fluid ounces per cycle, and losses above 2.7 fluid ounces,

[13:18]

or about a third of a cup, are considered heavy menstrual bleeding. I want you to ask yourself,

[13:24]

do I soak through pads or tampons every hour or two? Do I need double up on protection?

[13:32]

Do I wake at night to change products? Do I feel noticeably depleted, dizzy, exhausted,

[13:38]

or short of breath during my period? If the answer to several of these questions is yes,

[13:44]

it may be worth exploring further. So today's invitation is simple. Become curious about your

[13:49]

monthly blood balance. Okay? Just you have an account balance, a money balance, you have a

[13:53]

blood balance. Not fearful, not obsessive, just curious. Because what feels normal is not always

[14:01]

optimal, and understanding your own rhythm is often the first step towards better health.

[14:07]

If you donate your blood, please calculate how much you donate a year,

[14:11]

and maybe, maybe sometimes take a small pause, if that suits you better. And remember,

[14:18]

every small step you take moves you closer to freedom. You are powerful,

[14:22]

you are resilient, and you're not alone. Keep rising, Migrant Hero.
