The Perimenopause Symptoms Nobody Warned Us About

There’s this weird gap in women’s health where you go from “period chat at school” to “hot flushes and HRT”. And nobody really explains the messy middle bit.

That messy middle has a name: perimenopause.

For a lot of us, it doesn’t arrive with a big dramatic fanfare. It creeps in quietly. One day you’re just a bit more tired, a bit more snappy, your periods are a bit… odd. You put it down to stress, kids, work, life.

And then one day you realise:
“Oh. This might actually be a thing.”

This post isn’t medical advice (I’m not a doctor), but it is the honest, “why did nobody tell me this?” overview I wish we all got handed in our late 30s.

We’ll cover:

• What perimenopause actually is (in normal‑people language)
• Common symptoms nobody warned us about
• How it can show up in everyday life
• Small, practical things that can help
• When to talk to a GP or specialist

What Is Perimenopause, Really?

Perimenopause is the transition into menopause.

It’s the period of time when your hormones – mainly oestrogen and progesterone – start to fluctuate and gradually decline. Your body is essentially shifting from a fertile phase into a non‑fertile one, and it doesn’t always do it quietly or politely.

You’re officially in menopause when you’ve gone 12 months without a period.
Perimenopause is everything that happens before that.

For some women, it lasts a couple of years. For others, it can be closer to a decade. It often starts in your 40s, but it can begin earlier or later – our bodies don’t read the rule book.

The important bit:
If you’re in your 40s, your cycle is changing, and you feel like your body and brain are behaving differently… you’re not imagining it.

The Symptoms No One Warned Us About

We’ve all heard about hot flushes and night sweats. But perimenopause can show up in so many other ways that are much easier to dismiss or blame on “being busy”.

Every woman’s experience is different, but here are some of the common symptoms that often take people by surprise – including the ones that hit me hardest.

1. Anxiety and Mood Swings

You might notice:

• Feeling more anxious or on edge than usual
• Worrying about things that never used to bother you
• Sudden dips in mood or feeling low for no obvious reason
• Feeling more irritable or snappy (especially around your period)

For me, anxiety went through the roof. Things I would have taken in my stride before suddenly felt huge. My confidence in myself and my abilities just… disappeared. I started second‑guessing everything – work decisions, parenting, even simple day‑to‑day things.

2. Sleep Going Completely Rogue

Perimenopause can be brutal on sleep:

• Waking up at 3am and not being able to get back to sleep
• Lighter, more broken sleep
• Night sweats that leave you hot, clammy and wide awake
• Struggling to switch off, even when you’re exhausted

You end up permanently tired but wired – which, of course, makes everything else feel harder.

3. Periods That Don’t Play by the Rules

Your cycle might:

• Get shorter or longer
• Become heavier or lighter
• Arrive early, late, or skip a month completely
• Come with more intense PMS symptoms

For me, it was really heavy periods – the kind that make you plan your day around where the nearest loo is and what you’re wearing. It’s not just inconvenient; it’s exhausting and can be quite scary when you don’t realise it’s linked to perimenopause.

4. Brain Fog and Concentration Issues

This one can be really unsettling.

You might notice:

• Forgetting words mid‑sentence
• Walking into a room and having no idea why you’re there
• Struggling to focus on tasks you used to breeze through
• Feeling generally “foggy” or spaced out

It’s not that you’re suddenly less capable. Your brain is responding to hormonal changes and lack of decent sleep – plus the mental load you’re already carrying.

5. Aches, Pains and Physical Changes No One Mentioned

This was one of the biggest shocks for me.

I started to feel achy all over – like I was dragging my butt around in a body that felt about 200 years old. Joints, muscles, that general “stiff and sore” feeling when you get up or move around. It’s easy to write it off as “getting older” or “being unfit”, but hormonal changes can absolutely play a part.

On top of that, there were changes to how I looked:

• Hair thinning and becoming more brittle, which can really knock your confidence
• Skin feeling drier or more sensitive
• Weight shifting, especially around the middle

And then there are the more intimate changes:

• Vaginal dryness or discomfort
• Lower libido
• Discomfort during sex

All of which can impact how you feel in your body, in your clothes, and in your relationships.

How It Can Feel in Real Life

On paper, these are “symptoms”. In real life, it can look like:

• Snapping at your kids or partner and then feeling guilty for hours
• Standing in front of your wardrobe, hating everything, and not quite knowing why
• Feeling like your body has changed shape overnight, especially around your tummy
• Waking up tired, going to bed tired, and living on caffeine and willpower
• Wondering if you’re “losing it” because you can’t remember anything

For me, it was this messy combination of:

• Aching all over, like my body was twice my age
• Dragging myself through the day, feeling heavy and exhausted
• Hair thinning and feeling more brittle, which made me feel less like “me” when I looked in the mirror
• Anxiety dialled up to maximum, with my confidence in myself and my abilities pretty much vanishing
• Really heavy periods that were draining physically and emotionally

None of it arrived with a neat label saying “Hi, I’m perimenopause.” It just felt like I was falling apart a bit – until I started joining the dots.

If any of that sounds familiar, you’re not alone – and you’re not making it up.

Small, Practical Things That Can Help

Perimenopause is big and complex, and sometimes you absolutely do need medical support (we’ll talk about that in a second). But there are also small, everyday things that can make a real difference.

Think of these as tiny levers you can pull, rather than a complete life overhaul.

1. Sleep: Protect It Like a Toddler’s Bedtime

You’ve probably heard all the sleep advice before, but in perimenopause it becomes less “nice to have” and more survival strategy.

A few realistic tweaks:

• Consistent-ish bedtime: aim for roughly the same sleep and wake times most days.
• Wind‑down window: 20–30 minutes before bed without doom‑scrolling – read, stretch, or watch something gentle.
• Cool bedroom: lower temperature, lighter bedding, breathable pyjamas if night sweats are a thing.
• Parking your brain: keep a notebook by the bed to dump worries or to‑dos before you try to sleep.

None of this has to be perfect. Even one small change can help.

2. Gentle Movement Over Punishment Workouts

If your energy is low, your joints ache, and you’re not sleeping properly, the last thing you need is a brutal workout you dread.

Instead, focus on:

• Walking (school run, lunchtime, after dinner – it all counts)
• Short home workouts or YouTube videos
• Stretching or yoga, even for 5–10 minutes
• Strength work with light weights or bodyweight, if/when you can

Movement can help with mood, sleep, stress and joint health – but it doesn’t have to look like a gym membership and a new personality.

3. Food and Hydration That Support You

You don’t need a perfect diet. You’re not failing if you like biscuits.

But some gentle shifts can help with energy and mood:

• Regular meals to avoid blood sugar crashes (which can make anxiety and irritability worse)
• Plenty of protein and fibre to keep you fuller for longer
• Drinking enough water (especially if you’re having hot flushes or night sweats)
• Noticing how caffeine and alcohol affect your sleep and mood, and adjusting if needed

Think of it as supporting your body, not punishing it.

4. Stress: Tiny Boundaries, Big Difference

Hormonal changes can make you more sensitive to stress, so things that were “fine” before might now feel overwhelming.

Small boundaries can help:

• Saying no to the extra thing you really don’t have capacity for
• Protecting one small pocket of time each week that’s just for you
• Asking for help at home instead of silently doing everything

You don’t have to fix your whole life. Just look for one place you can take the pressure down a notch.

5. Talk About It

Perimenopause loves secrecy and shame. Talking about it takes some of that power away.

You might:

• Mention how you’re feeling to a friend and realise she’s going through the same
• Share an article or podcast with your partner so they understand what’s happening
• Join an online community or follow accounts that talk honestly about midlife and hormones

You don’t have to turn it into your whole personality – just give yourself permission to say, “This is happening, and it’s hard sometimes.”

When to Talk to a Doctor

As much as lifestyle tweaks can help, they’re not a replacement for proper medical support.

It’s worth talking to your GP or a menopause specialist if:

• Your mood is very low or you’re struggling with anxiety
• Your sleep is consistently poor and affecting your daily life
• Your periods are extremely heavy, painful or unpredictable
• You’re having intense hot flushes or night sweats
• You just feel “not yourself” and it’s worrying you
• Aches, pains or heart palpitations are frequent or severe

You can:

• Keep a simple symptom diary for a few weeks (sleep, mood, cycle changes, physical symptoms like aches, hair changes, heavy bleeding)
• Take it to your appointment so you’re not trying to remember everything on the spot
• Ask specifically about perimenopause and options like HRT, non‑hormonal treatments and lifestyle support

You deserve to be taken seriously. You’re not being dramatic. You know your body better than anyone.

You’re Not Broken – You’re Changing

Perimenopause can feel like someone has quietly swapped your body and brain for a slightly glitchy version.

You’re more tired. Your jeans fit differently. Your patience is thinner. Your neck has lines that weren’t there before. Your once‑reliable brain occasionally forgets the word for “kettle”. Your hair isn’t behaving like it used to. Your joints ache when you get up.

It’s a lot.

But you’re not broken. You’re not failing at coping. You’re moving through a huge hormonal transition while still doing school runs, work, laundry, relationships and life.

Your next tiny step:
If anything in this post sounded familiar, pick one small thing to try this week:

• Go to bed 20 minutes earlier
• Add a short walk into your day
• Make a GP appointment
• Text a friend and say, “I think I might be in perimenopause – can we talk about it?”
