You’re in your late thirties, forties, or early fifties. You’re exhausted in a way that feels bone-deep. Your sleep is all over the place. You’re snapping at people you love and then feeling terrible about it. Your brain isn’t working the way it used to. And underneath all of it is a low hum of anxiety you just can’t switch off.
So what’s going on?
Two of the most common things I hear from women in this situation are: “I think I’m burning out” and “I wonder if this is perimenopause starting.” And here’s the thing, both might be right. Or one might be masking the other. Or what looks like burnout is actually a hormonal shift, or vice versa.
It matters which it is, because the support for each looks quite different. But it’s complicated, because these two experiences share a lot of the same symptoms, and they frequently happen at the same time, in the same women, often for related reasons.
Here’s what we know.
What Is Perimenopause, Really?
Perimenopause is the transition phase leading up to menopause: the point at which your periods have stopped for twelve consecutive months. It can begin anywhere from your late thirties onwards, though most women start noticing changes in their mid-to-late forties. For some it lasts a couple of years. For others, it can go on for a decade.
During perimenopause, oestrogen and progesterone begin to fluctuate and gradually decline. It’s rarely a smooth, gradual descent. It’s more like a road with unexpected dips and surges, and this is part of why the symptoms can feel so unpredictable.
Common signs of perimenopause:
- Irregular periods: shorter or longer cycles, heavier or lighter bleeds, or periods becoming less predictable
- Hot flushes and night sweats: sudden waves of heat, often accompanied by flushing and sweating
- Sleep disruption: difficulty falling asleep, waking in the night, or waking early and being unable to get back to sleep
- Mood changes: anxiety, low mood, tearfulness, or emotional volatility that feels out of character
- Brain fog: word-finding difficulties, memory lapses, difficulty concentrating
- Weight changes: particularly around the middle, despite no change in diet or exercise
- Low libido: reduced interest in sex, sometimes accompanied by vaginal dryness or discomfort
- Joint aches and pains: less commonly discussed but a recognised symptom linked to oestrogen’s anti-inflammatory role
- Heart palpitations: an awareness of the heartbeat that can feel alarming but is often hormonal in origin
Some women sail through with minimal disruption. Others find it debilitating. And many, particularly those who don’t connect their symptoms to hormonal change, spend months or years not understanding why they feel so unlike themselves.
What Is Burnout, Really?
Burnout is a state of physical, emotional, and mental exhaustion caused by prolonged and unrelenting stress. It’s not just being very tired. It’s what happens when your nervous system has been running on high alert for too long without adequate recovery, until something gives.
The three hallmarks of burnout, as defined by researchers, are: emotional exhaustion, a sense of cynicism or detachment from things that used to matter, and a feeling of reduced effectiveness or capability. In practice, it tends to show up as a whole cluster of physical and psychological symptoms.
Common signs of burnout:
- Chronic exhaustion: a tiredness that goes beyond physical fatigue, where even rest doesn’t restore you
- Emotional flatness or detachment: feeling disconnected from your work, relationships, or things you used to enjoy
- Dread and overwhelm: a sense that everything is too much, and difficulty with tasks that used to feel manageable
- Anxiety and irritability: being short-tempered, hypervigilant, or in a constant low-level state of stress
- Sleep problems: particularly struggling to switch off at night despite being exhausted, or waking at 3am with your mind racing
- Brain fog and poor concentration: difficulty thinking clearly, making decisions, or retaining information
- Physical symptoms: headaches, digestive issues, lowered immunity, getting ill more frequently
- Loss of motivation: things that once felt meaningful or enjoyable now feeling effortful or pointless
Burnout doesn’t usually arrive suddenly. It’s the result of running on empty for too long and ignoring the signs that your tank needed refilling.
Why They’re So Easy to Confuse
Look at those two symptom lists side by side and you’ll notice something immediately: they’re nearly identical in several key areas.
Fatigue. Sleep disruption. Anxiety. Brain fog. Mood changes. Poor concentration. These are symptoms of both perimenopause and burnout. Which is why so many women, and so many healthcare providers, struggle to tell them apart.
But there’s a deeper reason they’re so intertwined, and it goes beyond symptom overlap.
Stress accelerates hormonal change
Chronic stress has a direct effect on your hormonal system. When your body is under sustained pressure, it prioritises the production of cortisol (your stress hormone) over sex hormones like progesterone and oestrogen. This is sometimes called the “pregnenolone steal”: your body diverts the raw materials it would normally use to make progesterone towards making cortisol instead.
The result? Lower progesterone. More hormonal volatility. Disrupted sleep. Heightened anxiety. Weight changes.
Sustained stress doesn’t just cause burnout symptoms in their own right. It actively worsens the hormonal imbalance that drives perimenopausal symptoms. The two feed each other.
A woman in her mid-forties dealing with high levels of stress and insufficient recovery isn’t just burning out. She may also be accelerating her hormonal transition.
Perimenopause makes you more vulnerable to burnout
The relationship runs in the other direction too. The hormonal shifts of perimenopause (declining progesterone, fluctuating oestrogen, disrupted cortisol patterns) reduce your resilience to stress. Things that felt manageable before can start to feel overwhelming. Your buffer has shrunk.
So you may not have more stress than before. You just have fewer hormonal resources to cope with it.
How to Tell Them Apart: Key Differences
While they share a great deal of common ground, there are some distinguishing features that can help point you in the right direction.
Pointers towards perimenopause:
- Age: if you’re in your late thirties or older, perimenopause is worth considering even if you think you’re too young
- Menstrual changes: any shift in your cycle pattern (timing, flow, frequency) is a significant indicator
- Physical symptoms with no obvious stress trigger: hot flushes, night sweats, vaginal dryness, joint pain, and heart palpitations tend to be hormonal rather than stress-related
- Cyclical symptom patterns: if your symptoms track with your cycle, worse in the week before your period for example, this often points to hormonal fluctuation
- Worsening PMS: many women notice their previously manageable PMS becoming significantly more intense in the years leading up to menopause
Pointers towards burnout:
- A clear link to workload or life circumstances: if symptoms began or significantly worsened during a period of high demand, this is an important clue
- Emotional exhaustion and detachment: a cynicism or disconnection that feels specific to your work or responsibilities rather than generalised
- The sense that you’ve hit a wall: a sudden or marked deterioration after a sustained period of overdoing it
- Symptoms that fluctuate with stress levels: if you feel noticeably better on holiday or during lower-demand periods, this suggests a stress-driven pattern
- No menstrual changes: if your cycle is completely regular and unchanged, the hormonal shift of perimenopause is less likely (though not impossible) to be the primary driver
These are pointers, not a diagnostic tool. The truth is that many women will see themselves in both lists. Which is exactly the point.
Why It Matters Which It Is
You might be wondering: does it actually matter what we call it, as long as I start feeling better?
Yes. Here’s why.
If you’re primarily burnt out and you treat it as perimenopause (or wait for it to pass as a hormonal phase), you’ll likely stay burnt out. The chronic stress driving your symptoms won’t resolve on its own, and it will continue to affect your physical health, your relationships, and your hormonal balance.
If you’re primarily in perimenopause and you treat it as burnout (rest more, do less, manage your workload), you may feel somewhat better, but you’ll be missing the hormonal support your body actually needs at this stage.
If it’s both (which is common), then you need a plan that addresses both. That means understanding your cortisol pattern alongside your sex hormones, because the approach for high cortisol is different from the approach for low progesterone, and both need to be addressed in the right order.
Getting clarity on what’s driving your symptoms isn’t just semantics. It’s the difference between a plan that works and one that doesn’t.
So What Do You Actually Do?
The first step is to stop guessing and start looking at what’s happening inside your body.
This is where testing becomes invaluable. Specifically, the DUTCH Complete Test.
The DUTCH test is a dried urine test that gives a comprehensive picture of both your sex hormones and your stress hormones. It doesn’t just measure levels: it shows how your body is metabolising and processing each hormone. And it maps your cortisol pattern across the full day, including the critical cortisol awakening response, something a standard blood test simply cannot do.
What the DUTCH test can show us:
- Whether your oestrogen and progesterone are shifting in ways consistent with perimenopause
- Whether your cortisol pattern shows signs of HPA axis dysfunction (the physiological signature of burnout)
- Whether both are happening simultaneously, and to what degree
- Which hormonal pathways need the most support, and in what order
With those results, we can build a nutritional and lifestyle plan that targets what’s actually going on, not just the symptoms on the surface.
You don’t have to choose between “it’s hormones” and “it’s stress”. The DUTCH test shows you both, and how they’re interacting.

A Final Note
If you’re reading this and recognising yourself, in one picture or both, I want you to know something.
The fact that your symptoms are hard to pin down, that they don’t fit neatly into one box, that even the people around you might not fully understand what you’re going through, none of that means they’re not real. It means they’re complex. And complexity deserves a thoughtful, personalised response.
You don’t have to push through this on your own. You don’t have to settle for feeling like a lesser version of yourself.
If you’d like to explore what’s going on for you specifically, I’d love to hear from you.
