5 Signs Your Migraine Threshold Might Be Low (And Why That Matters More Than “Finding THE Trigger”)

A lot of people with migraine spend years trying to figure out the One Thing causing their attacks.

THE food.
THE weather pattern.
THE hormone issue.
THE preservative.
THE type of lighting.
THE tight muscle.

And while triggers absolutely matter… there’s a potentially BIGGER piece of the puzzle that often gets overlooked: your migraine threshold.

Because as I’m sure you’ve noticed (and been frustrated by), two people with migraine can be exposed to the exact same trigger, but only one of you ends up in a dark room with an ice pack trying not to throw up.

That’s because migraine isn’t just about the triggers themselves. It’s also about how readily your nervous system reacts to those triggers in the first place.

When your threshold is low, your nervous system is much more likely to be affected by triggers and experience an attack. And THAT’S when life starts to feel like walking a tightrope.


Signs your migraine threshold may be low:

1. You constantly feel like you’re on the verge of an attack

Not necessarily a full-blown migraine attack every second (although that can happen too), but that feeling of:

  • pressure behind the eyes

  • neck tension

  • mild dizziness

  • lightheadedness

  • fatigue

  • brain fog

  • sound sensitivity

  • nausea

  • feeling “off”

  • waking up already feeling fragile

A lot of people end up normalizing this because it’s become their baseline, or are told that these symptoms are just “part of living with migraine”. But if you constantly feel like you’re one minor inconvenience away from spiraling into a migraine attack, that’s often a sign your system is likely already overloaded before your day even begins.

2. Your meds help… but not as much as you’d like

This one can be SO frustrating, because medications are typically the main tool we’re given to manage migraine day-to-day. It’s easy to assume that if medications aren’t working perfectly, you just haven’t found the right one yet (or worse, that you’re a hopeless case and nothing will work).

But when trying medication after medication just doesn’t do the trick, it’s possible that there’s something getting in the way of those medications being able to work in the first place..

That might be a digestive issue, an absorption issue, or simply a threshold that’s just too low to be brought up with medications alone.


3. Your triggers make no sense

One day wine causes an attack, the next day it doesn’t.

One week you tolerate an overseas trip just fine, but the next week a slightly late lunch wipes you out.

This is one of the biggest examples of how migraine is typically less about a single trigger, and more about the total load your body is carrying.

You can think of it like a bucket being filled with water:

  • A poor night’s sleep - add water.

  • A stressful morning - add water.

  • Skipping breakfast - add water.

  • Entering your luteal phase - add water.

  • That cute glass of wine because you had a day - overflows the bucket.

If you have a small bucket (aka a low threshold), it takes very little water to make it overflow. This means that everything can feel like a trigger, but at the same time triggers seem all over the place.

4. You have symptoms even outside of migraine attacks

This is such an important one! A lot of people with migraine are not just dealing with attacks, but symptoms that happen on a daily basis like:

  • fatigue

  • GI issues

  • dizziness

  • anxiety

  • feeling wired but exhausted

  • blood sugar crashes

  • brain fog

  • sensory overwhelm

  • sleep problems

  • chronic tension


These are often called interictal symptoms, or symptoms that happen between migraine attacks. Interictal symptoms are often overlooked because they aren’t accounted for when your doctor asks “how many migraine attacks do you have per month”, but they’re a BIG sign that your migraine threshold is low and needs some support!


5. You feel like you have to do everything “perfectly” to function

This is a common one for my perfectionists (which let’s be real, migraine turns a lot of us into unwilling perfectionists!).

It can feel like you:

  • can’t eat one “wrong” thing

  • can’t sleep in even 5 minutes

  • can’t miss a single dose of your supplements

  • can’t enjoy one sip of wine

  • can’t have one spontaneous day

… because if you do, your body punishes you for it with an attack.

That hypervigilance gets exhausting!! And ironically, it can make migraine feel even more consuming and life-altering.

So… how do you actually raise your migraine threshold?

This is where it’s easy to get ahead of yourself. I see so many people jumping immediately into:

  • researching histamine theories

  • deep-diving on mold toxicity

  • starting 27 supplements

  • intense diets like Heal Your Headache

  • expensive lab tests and protocols

… while their basic needs are sitting there like “hey, can we try eating breakfast please?”.

And look, I’m not judging you for this - I’ve been there before, several times. But before going down complicated rabbit holes, it’s usually worth asking:

Are your basic physiological needs consistently supported?

Things like:

  • eating enough, consistently

  • balancing protein, fat, carbs, and fiber

  • stabilizing blood sugar

  • hydrating adequately

  • getting electrolytes if needed

  • improving sleep consistency and quality

  • exercising in a supportive way

  • reducing obvious nervous system overload

  • pacing better instead of living in push-crash cycles

  • learning your body’s patterns without obsessing over every symptom


And the fun thing is, sometimes improving those foundational things creates WAY more progress than people expect!

Not because migraine is “easy to fix” (we all know it’s absolutely not), but because a stressed, under-fueled, dysregulated body is much more prone to migraine attacks.

But when the basics don’t move the needle enough…

That’s when it 100% makes sense to dig deeper into the fun stuff like:

  • nervous system hyperactivity / neurotransmitter imbalance

  • gut-brain communication issues

  • microbiome disruption

  • funky hormone patterns

  • vitamin and mineral deficiencies

  • digestion and absorption issues

  • metabolic or detoxification problems

  • excess inflammation

  • histamine build-up

An added bonus to all of this - if you’re someone who deals with any of the conditions that are commonly seen alongside migraine (like IBS, dysautonomia, chronic fatigue, autoimmunity, thyroid issues, PMS, anxiety disorders), you can often see improvements in these areas too when you address both the basics and the deeper imbalances.

That’s because the body isn’t a bunch of disconnected systems operating independently from each other - it’s all connected!


Final thoughts

If you’ve been feeling like your body is “too sensitive,” “too reactive,” or like migraine is just impossible to figure out… that doesn’t mean you’re doomed or beyond hope!

In the vast majority of cases, working on building a higher threshold thoughtfully and consistently can help you finally move the needle.
