Is This Perimenopause, Or Is Your Gut Trying to Tell You Something?

"I don't know what's happening to my body." It's something I hear from women almost every week. And more often than not, the answer involves both perimenopause and the gut, working against each other in a loop that nobody warned them about.

You're in your early-to-mid forties. You're eating well — or at least you're trying to. But your stomach is unpredictable, your energy has flatlined, your mood swings arrive without warning, and there's a brain fog that follows you around like a shadow. You've started wondering whether this is just what getting older feels like.

It isn't. And here's what's really going on.

Perimenopause, the transitional phase that can begin anywhere from your late thirties to your early fifties, comes with a well-known list of symptoms. But what most women (and many GPs) don't realise is that many of those same symptoms are also classic signs of a gut that is struggling.

Look at this list and ask yourself how many feel familiar:

• Bloating that seems to appear from nowhere, regardless of what you eat

• Exhaustion that isn't fixed by a full night's sleep

• Mood swings, anxiety, or a low-level sadness you can't quite explain

• Brain fog — that frustrating sense of thinking through treacle

• Weight gain around the middle despite no change in diet

• Skin changes — dryness, dullness, or new sensitivities

• Disrupted sleep, even when hot flushes aren't the culprit

• Feeling "off" — not ill exactly, just not yourself

If you ticked most of those, you might have been told it's "just hormones." And hormones are absolutely part of the story. But they're not the whole story, and treating only the hormones while ignoring the gut is like turning down the smoke alarm instead of putting out the fire.

"Most women in perimenopause are told to manage their hormones. Very few are told that their gut health is either driving their symptoms — or making them significantly worse."

Here's the biology that changes everything. As oestrogen begins to fluctuate and decline during perimenopause, it directly affects the gut microbiome. The trillions of bacteria that live in your digestive system and regulate everything from your immune response to your mood.

Oestrogen plays a key role in maintaining the diversity of your gut bacteria. When it drops, the microbiome can become imbalanced, a state known as dysbiosis. And dysbiosis doesn't just cause digestive symptoms. It affects your entire body.

At the same time, your gut produces approximately 95% of your body's serotonin, the neurotransmitter most associated with mood, calm, and emotional stability. When the microbiome is disrupted, serotonin production falls. Which means the anxiety, the low mood, and the emotional volatility that many women experience in perimenopause are not simply "in their heads." They are, quite literally, in their gut.

Here's what's really important to understand: perimenopause and gut imbalance feed each other in a loop. Your hormones shift, and that throws your gut off balance. Your gut gets disrupted, and suddenly your hormonal symptoms feel worse. And then there's the stress, the kind that creeps in when you're not feeling like yourself, when everything feels like too much, and that stress disrupts both your hormones and your gut microbiome even further.

So it's not one single thing causing what you're feeling. It's a cycle. And the only way to break a cycle is to interrupt it in more than one place at a time.

That's exactly why my Core Courage Program works the way it does, we address the gut, the hormones, the stress response, and the emotional patterns together, all at once. Because when you only work on one piece, the rest just pulls you back into the same loop.

One question I hear again and again is whether to focus on hormones or gut health. Here's the thing, for most of us in perimenopause, it's genuinely not one or the other. But there are some clues worth paying attention to if your gut is the bigger driver:

• Your symptoms are worse after eating - particularly after sugar, alcohol, processed foods, or foods you've always tolerated fine before

• Your mood dips significantly after meals - this can indicate blood sugar instability driven by gut imbalance

• You're bloated most of the time - not just around your cycle

• You've noticed increased food sensitivities- that weren't there five years ago

• Stress makes your gut symptoms immediately worse - a classic sign of an overactive gut-brain stress response

• Your sleep is poor even on nights without hot flushes - poor gut health disrupts the production of melatonin as well as serotonin

If several of these resonate, your gut deserves serious attention, not as an alternative to addressing your hormones, but alongside it.

True holistic menopause support doesn't put you on a supplement protocol and leave you to it. It looks at the whole picture: your gut microbiome, your stress levels, your nutritional status, your sleep quality, your emotional patterns, and the beliefs that have been quietly running your health decisions for years.

In practical terms, some of the most impactful things you can do right now to support both your gut and your perimenopausal symptoms:

1. PRIORITISE THE MICROBIOME

Add fermented foods daily, good quality live yoghurt, kefir, sauerkraut, kimchi. These feed the beneficial bacteria that oestrogen decline has been depleting. Aim for 30 different plant foods a week to maximise fibre diversity, which feeds a diverse microbiome.

2. ADDRESS THE GUT-STRESS LOOP DIRECTLY

Chronic stress is one of the most damaging things you can do to your gut microbiome. Not because you're "too sensitive," but because cortisol literally changes the composition of your gut bacteria within hours. Nervous system regulation, whether that's breath work, gentle movement, or simply building more genuine rest into your day is gut health work.

3. WATCH YOUR BLOOD SUGAR

Oestrogen helps regulate insulin sensitivity, so as it declines, blood sugar can become more erratic. This is why many perimenopausal women suddenly feel worse after eating carbohydrates they used to tolerate fine. Eating protein with every meal, reducing refined sugar, and not skipping meals all help stabilise blood sugar, which in turn reduces cortisol spikes and supports the gut lining.

4. BE HONEST ABOUT ALCOHOL

I say this with kindness, not judgement. Alcohol is one of the most disruptive things for both gut health and perimenopausal symptoms, it disrupts sleep architecture, raises cortisol, depletes the microbiome, and worsens hot flushes. Many women find that reducing or removing it is one of the fastest routes to feeling significantly better.

5. CONSIDER WHAT YOU HAVEN'T YET ADDRESSED

This is perhaps the most important one. In my experience working with women through perimenopause, the physical symptoms are almost always entangled with something emotional — a pattern of putting everyone else first, a long-held belief about not being allowed to slow down, a chapter of life that's asking to be grieved or released. The gut holds that too. The body keeps the score, as they say, and it is remarkably willing to begin healing once we give it the right conditions and the right support.

"Perimenopause is not a malfunction. It is a transition. And like all meaningful transitions, it asks you to pay attention to parts of yourself you may have been ignoring for a very long time."

If you've been feeling unwell and unseen — dismissed by your GP, told your results are 'normal' when nothing about how you feel is normal — I want you to know this: what you're experiencing is real, it's connected, and there is a way through it.

This isn't about piling more onto an already overwhelming plate. It's about finally understanding what your body is actually asking for, and giving it the right support — with knowledge, not guesswork.

I work with women at exactly this stage of life. Women who are done just managing symptoms and ready to actually understand what's happening in their bodies. If that's you, I'd love to chat.
