Have you ever wondered why a migraine can make your stomach completely revolt,
[00:04]
leaving you nauseous, unable to eat or even vomiting before the head's pain fully hits?
[00:10]
Today, we're diving into the fascinating and powerful connection
[00:14]
between your gut and your brain on nausea and migraine.
[00:20]
Welcome to Migraine Heroes, a podcast for people living with chronic migraines with years of pain,
[00:26]
misunderstanding and lack of answers. I'm Diane Ducarme. I've helped more than a thousand people
[00:33]
reduce the burden of migraines and feel more in control. My mission in life? To help a million
[00:39]
people. Each episode brings you grounded insight into what your body might be asking for and what
[00:46]
can truly help. Just to keep you fully supported, this podcast is educational. For diagnosis or
[00:54]
medication, always work with your doctor. Now, take a breath and let's dive in.
[01:06]
In this episode, you will learn why nausea is not just a side symptom of migraines but a core part
[01:11]
of the migraine process itself, how the gut-brain axis can amplify inflammation, stress signals and
[01:18]
nervous system overload that trigger migraine attacks, and a simple way to calm your digestive
[01:23]
system at home that may reduce the intensity of migraine-related nausea starting today.
[01:29]
Stay with me till the end because at the end of this episode, you will understand why
[01:33]
calming your gut may sometimes calm your migraine faster than focusing only on your head pain.
[01:40]
If you live with migraines, you probably know this feeling all too well. The wave of nausea,
[01:45]
sort of the sudden food aversion, the stomach cramping, the inability to digest properly,
[01:51]
that you have food in your stomach or not, or even vomiting during an attack. And honestly,
[01:57]
it can feel quite frightening at times. You may feel trapped between your brain and your stomach,
[02:03]
unable to function, eat or even think clearly. And if this is you, please know this. Your body
[02:09]
is not overreacting. There is a very real biological connection happening. The relationship
[02:14]
between migraine and nausea is deeply connected to what scientists now call the gut-brain axis.
[02:20]
And I'm sure you've heard of this. This is the two-way communication system between your
[02:25]
gastrointestinal tract and your central nervous system. And so your gut and your brain are
[02:30]
constantly talking to each other through your nerves, through your hormones, your immune signals,
[02:36]
and even your gut bacteria. And one of the key players here is the vagus nerve, which is often
[02:41]
called the superhighway between the gut and the brain. And the vagus nerve helps regulate digestion,
[02:47]
inflammation, heart rate, and stress responses. And during a migraine attack,
[02:51]
this communication pathway can become really disrupted. I don't know if you've ever watched
[02:56]
small children. So they sort of share an ice cream together and one of them suddenly eats it
[03:01]
far too quickly and grabs their forehead and laughs, brain freeze, and only to encourage the
[03:06]
other children to try it too. And it's very cute to watch, but it's also surprisingly revealing.
[03:11]
In this brief moment, the child is going to experience something completely profound.
[03:16]
It's going to experience for the first time the connection between their brain and their stomach.
[03:20]
When the stomach is suddenly exposed to intense cold, the sensation can travel upward and be
[03:26]
felt almost instantly in the forehead. It comes like a snap, sharp, sudden, but fleeting. And
[03:32]
the body reacts quickly, warming and melting the ice cream, almost immediately restoring that
[03:38]
balance. So what is fascinating is that the connection has been established. The child
[03:42]
intuitively realizes that the gas in the brain are deeply linked, that what happens in the stomach
[03:47]
does not stay in the stomach. The body speaks in pathways, echoes, and responses. So in the West,
[03:53]
we now know that the stomach can communicate continuously with the brain region involved in
[03:57]
emotions, stress, awareness, and cognition, including the prefrontal cortex. And research
[04:03]
published in Nature Reviews Neurology by Goatsby explained that migraines are not simply vascular
[04:10]
headaches that once we believed, but complex neurological events involving multiple systems,
[04:15]
including the digestive system. And during a migraine attack, the brainstem becomes activated,
[04:21]
particularly areas associated with nausea and vomiting. And this is going to include the
[04:26]
dorsal vagal complex, which directly influences the stomach function. So what does it mean in
[04:31]
practice? So it means your stomach may literally slow down during a migraine attack. This condition
[04:38]
is known as gastric stasis, where food is going to remain in the stomach longer than normal.
[04:45]
And studies published in the journal Cephalalgia found that migraine patients frequently experience
[04:51]
delayed gastric emptying, both during and between attacks. But why would that happen? Why would
[04:58]
nausea happen in the first place? Why would that gastric stasis happen in the first place?
[05:03]
Most nausea tends to come from five major events. The first one is irritation. Something
[05:09]
physically upsets your stomach. Food poisoning, it can be alcohol, a virus, overeating, reflux.
[05:15]
The body reacts almost protectively, saying, something here doesn't feel right. The second
[05:21]
comes from the balance system. And motion sickness here is a perfect example. So when your eyes,
[05:27]
your inner ears, and your body disagree about movement on a boat, or in turbulence, or in a car,
[05:33]
the brain can trigger nausea almost like an emergent response. So I don't know if you've
[05:38]
ever noticed, do you have more nausea and migraine while on the road? That's what I'm
[05:42]
talking about. The third involves hormones and chemistry. So pregnancy, hormonal shifts,
[05:48]
blood sugar crashes, all of these can activate nausea pathways because the brain is constantly
[05:53]
monitoring the chemistry of the body. The fourth is linked to stress and emotion. Most of us have
[05:58]
experienced this, this sick feeling before an exam. Nausea before public speaking, a sort of a
[06:04]
loss of appetite during grief or a heartbreak. And Western science now understands that the gut and
[06:09]
brain are in constant communication through what is called the gut-brain axis. So anxiety, fear,
[06:14]
overwhelm, and chronic stress can absolutely create physical nausea. And the fifth is protection.
[06:20]
Nausea is actually a survival mechanism. The body evolves to help protect us from toxins,
[06:26]
spoiled foods, infections, and danger. In many ways, nausea is the body choosing caution before
[06:32]
catastrophe. Because during a nausea, the stomach's normal rhythm and downward movement becomes
[06:38]
disrupted, while the brain and nervous system activates protective signals to slow the digestion
[06:45]
and prepare the body to reject or to avoid a perceived threat. In traditional Chinese medicine,
[06:51]
the perspective converges. In Chinese, there's a saying, and the saying goes like this,
[06:58]
when the stomach energy rebels upward, the head suffers. Yes, these guys have a saying for what
[07:05]
you feel so often, like there's a sentence for it. If you know me a little, you will know that
[07:10]
I love languages and travel. And so I've learned many languages in my life, about seven, and
[07:16]
Mandarin is one of them. And I find languages so revealing of a culture and so many other
[07:20]
learnings, and Mandarin is definitely one of them when it comes to Mandarin. In Chinese medicine,
[07:25]
the stomach is meant to send energy downward, calmly, smoothly, like a river flowing toward
[07:33]
the sea. But modern life often pulls us upward instead. We rush, we multitask, we ease while
[07:40]
answering emails, driving, scrolling, worrying. We live in a constant state of stimulation, and over time,
[07:46]
the body can lose its natural rhythm. And what Chinese medicine calls rebellious stomach qi is
[07:52]
when that downward flow reverses direction. Instead of grounding, the energy rises upward, showing up
[07:57]
as reflux, nausea, burping, tightness, or even, of course, headaches and migraines. It's fascinating
[08:03]
because the causes are often deeply human. Stress, overthinking, emotional tension, eating too quickly,
[08:09]
skipping meals, too much coffee, too little rest, not enough presence. And migraine and nausea are
[08:14]
not viewed as isolated symptoms. They are seen as signs as the body's internal energies are
[08:18]
struggling to move harmoniously. From an Eastern perspective, the body's not malfunctioning
[08:23]
randomly. It's trying to communicate imbalance. And in a more fundamental way, the stomach doesn't
[08:29]
just digest food, it digests life. And when life becomes too rushed, pressured, cold, irregular, or
[08:35]
emotionally overwhelming, or intoxicated with recreational and non-recreational toxins, the body
[08:42]
begins to rebel against the pace we're asking it to keep. Ayurveda, so the Indian traditions, offer
[08:48]
another interesting lens. In Ayurvedic medicine, migraines with nausea are linked often to the
[08:53]
imbalances of pitta and vata. And pitta relates to heat, intensity, inflammation, overdrive. And vata
[09:00]
relates to movement, the nervous system, instability, hypersensitivity. And so when
[09:05]
both become aggravated, symptoms such as throbbing headache, nausea, digestive upset, may merge
[09:11]
together. Eastern medicine often focuses less on suppressing symptoms and more on restoring rhythm.
[09:18]
Warm cooked foods, gentle routines, calming the nervous system, reducing overstimulation,
[09:24]
supporting digestion before forcing productivity. There's also a deep respect for the emotional
[09:30]
dimension of illness. In many Eastern traditions, digestion is not just about food, it's also about
[09:36]
what you are emotionally trying to process. And sometimes migraines appear when the body feels
[09:41]
overloaded, physically, emotionally, mentally, or energetically. So rather than asking
[09:47]
what is wrong with me, Eastern philosophy gently asks, what is my body trying to tell me?
[09:52]
That shift alone can change the entire healing journey. So what can you do today from your home?
[09:57]
Today, I'd like you to try this simple gut brain calming ritual at home. When nausea or migraine
[10:02]
symptoms begin, sit somewhere quiet and place one hand on your chest, one hand on your stomach,
[10:08]
and slowly inhale through your nose for four seconds, exhale for six seconds, for two minutes.
[10:14]
Then chew, if you have nausea and migraines often, keep them in your fridge. Chew some candied ginger
[10:19]
slowly, no ice cold, no ice drinks, avoid screen and harsh light for just 10 minutes if possible.
[10:28]
And this combination can help activate your vagus nerve, calm your nervous system, and support
[10:33]
digestion gently instead of forcing your body into more stress. Small signals of safety can
[10:39]
sometimes interrupt the migraine spiral earlier than you think. And by no stretch of imagination
[10:44]
am I saying things are that simple. Sometimes, and maybe for your profile, things are incredibly
[10:50]
complex and incredibly difficult. And if that's you, then search for this podcast and then search
[10:56]
in our podcast for other keywords beyond nausea, what else is happening, so you can rebuild a whole
[11:02]
mental picture of what's happening in your body and have lots of these small advice that help you
[11:08]
make the right decisions and more and more better decisions that allow you to regain control.
[11:14]
And remember, every small step you take moves you closer to freedom. You are powerful,
[11:21]
you are resilient, and you're not alone. Keep rising, Migraine Hero.
