Perimenopause symptoms: the signs, the myths and what actually helps
You’re sleeping badly, your periods have started doing their own thing, and you’ve found yourself walking into a room and forgetting why. Maybe your mood feels shorter than it used to, or you wake up drenched at 3am. You might put it down to stress, a busy job or just getting older.
For many women in their 40s, these changes have a name: perimenopause. It’s the stage before the menopause, and it can start years earlier than most people expect. The good news is that once you know what’s going on, there’s a lot that can help.
This guide explains the common and not-so-common perimenopause symptoms, when tests are useful (and when they’re not), your treatment options, and why this is a good time to think about your long-term health. At OneMedicine, we see women at every point of this transition, and we hear the same thing again and again: I wish I’d known sooner.
What is perimenopause?
Perimenopause is the time when your hormone levels, mainly oestrogen and progesterone, start to rise and fall unevenly as your ovaries slow down. It ends with the menopause, which is officially reached when you haven’t had a period for 12 months in a row.
A few useful numbers:
- In the UK, the average age of menopause is 51
- Perimenopause usually starts in your mid-40s, but it can begin earlier
- It typically lasts around four years, though for some women it’s a few months and for others it’s ten years or more
- Menopause before 45 is called early menopause, and before 40 it’s known as premature ovarian insufficiency. Both need to be properly assessed by a doctor
Because hormone levels go up and down rather than falling steadily, symptoms often come and go. You might feel fine for weeks, then have a rough patch. That unpredictability is one of the reasons perimenopause is so often missed.
The signs of perimenopause, grouped by how they affect you
Most people know about hot flushes. Far fewer know that anxiety, joint pain or palpitations can be part of the same picture. Here are the signs of perimenopause we see most often, grouped so you can spot patterns.
Changes to your periods
This is often the first sign. Periods may become:
- Closer together or further apart
- Heavier or lighter than usual
- More painful, or with worse premenstrual symptoms
- Skipped altogether for a month or two, then back again
Body temperature and sleep
- Hot flushes: a sudden wave of heat through the chest, neck and face, sometimes with redness and sweating
- Night sweats: hot flushes during sleep that can soak your bedding
- Poor sleep: trouble falling asleep, waking early, or waking several times a night, even without sweats
Mood and mind
- Low mood, tearfulness or feeling flat
- Anxiety, sometimes for the first time in your life
- Irritability and a shorter fuse
- Brain fog: forgetfulness, losing words mid-sentence, finding it harder to concentrate
Many women are offered antidepressants for these symptoms without anyone mentioning perimenopause. If the timing fits, it’s worth asking the question.
The less obvious physical signs
- Aching joints and muscles
- Headaches, or migraines that get worse or change pattern
- Palpitations: a fluttering, racing or pounding heartbeat
- Tiredness that doesn’t lift with rest
- Dry, itchy skin and thinning hair
- Weight gain, especially around the middle
Intimate and urinary symptoms
- Vaginal dryness, itching or discomfort during sex
- Lower sex drive
- Needing to wee more often, or more urinary infections
These are very common and very treatable, but they’re often the symptoms people feel least comfortable raising. A good GP will ask about them directly, so you don’t have to bring them up first.
When symptoms need checking quickly
Most perimenopause symptoms are uncomfortable rather than dangerous. But some changes should never be put down to hormones without a proper check. Book a private GP appointment promptly if you have:
- Bleeding after sex or between periods
- Very heavy bleeding, especially with clots or flooding
- Any bleeding after your periods have stopped for 12 months
- Palpitations with chest pain, breathlessness, dizziness or fainting
- Thoughts of self-harm or feeling unable to cope (in this case, contact your GP the same day, call NHS 111, or ring 999 in an emergency)
Do you need a blood test to diagnose perimenopause?
This surprises a lot of people, but often the answer is no.
National guidance from NICE says that for women over 45 with typical symptoms, perimenopause can be diagnosed based on your symptoms and periods alone. Hormone tests such as FSH aren’t usually needed, because your levels change from day to day. A single test can come back “normal” even when you’re clearly perimenopausal, which can be confusing and falsely reassuring.
That doesn’t mean blood tests have no role. They can be very useful to:
- Rule out other causes. An underactive or overactive thyroid, anaemia, low vitamin D, low B12 and diabetes can all cause tiredness, low mood and brain fog. A thyroid test or full blood count can make sure nothing else is being missed
- Check for anaemia if your periods have become heavy
- Assess younger women. If you’re under 45, and especially under 40, hormone tests are more helpful and an early diagnosis matters
- Look at your wider health, such as cholesterol and blood sugar, which become more important after the menopause
At OneMedicine, we’ll only recommend tests that will actually change what we do next.
If tests are needed, they can be arranged after a private GP appointment or an online consultation, and your doctor will go through the results with you so you know exactly what they mean.
Perimenopause treatment: your options
There’s no single right answer. The best perimenopause treatment depends on your symptoms, your health history and what matters most to you. Here are the main options.
Hormone replacement therapy (HRT)
HRT replaces the oestrogen your body is making less of. If you still have a womb, you’ll also take a progestogen to protect the womb lining.
- It’s the most effective treatment for hot flushes and night sweats, and often helps with sleep, mood, joint aches and brain fog
- Oestrogen can be taken as patches, gel or spray through the skin. These carry no extra risk of blood clots compared with not taking HRT, unlike tablets
- “Body-identical” hormones, which match the hormones your body makes, are widely available
- HRT also helps protect your bones
HRT isn’t right for everyone, and the risks and benefits are different for each woman. For most women under 60, the benefits outweigh the risks, but this needs an individual discussion with a doctor who knows your history.
At OneMedicine, we go through your personal and family history in detail before recommending any treatment, and we review how you’re getting on after you start.
Vaginal oestrogen
For dryness, discomfort and urinary symptoms, a low-dose oestrogen cream, pessary or ring used directly in the vagina works very well. Very little is absorbed into the rest of the body, so it’s suitable for most women, including many who can’t take standard HRT.
Non-hormonal medicines
If HRT isn’t suitable or you’d rather not take it, some non-hormonal medicines can reduce hot flushes. Your GP can explain which might suit you.
Talking therapy
Cognitive behavioural therapy (CBT) is recommended in national guidance for low mood and anxiety linked to the menopause, and it can also help you cope with hot flushes and poor sleep.
Lifestyle changes that make a real difference
- Regular exercise, including strength training
- Cutting back on alcohol and caffeine, which can trigger flushes and disturb sleep
- Stopping smoking
- Keeping your bedroom cool and wearing layers
- Building in time to rest and manage stress
A quick comparison
Option | Best for | Things to know |
|---|---|---|
HRT | Hot flushes, sweats, sleep, mood, bone protection | Most effective option; needs an individual risk discussion |
Vaginal oestrogen | Dryness, discomfort, urinary symptoms | Low dose, suitable for most women |
Non-hormonal medicines | Hot flushes when HRT isn’t suitable | Less effective than HRT for most women |
CBT | Low mood, anxiety, coping with flushes | Can be used alongside other treatments |
Lifestyle changes | Everyone | Helps on its own and alongside treatment |
Why perimenopause matters for your bones and heart
Perimenopause isn’t only about how you feel today. Oestrogen helps protect both your bones and your heart, and as it falls, both need more attention.
Your bones
Bone loss speeds up in the years around the menopause, and you won’t feel it happening. That’s why perimenopause is a good moment for a bone health review, especially if you have other risk factors such as a family history of hip fracture, low body weight, smoking, heavy drinking or long-term steroid use.
Simple steps make a difference:
- Weight-bearing exercise such as brisk walking, dancing or resistance training
- Enough calcium from food such as dairy, fortified plant milks, tinned fish with bones and leafy greens
- A vitamin D supplement, particularly from October to March, as UK guidance recommends
A bone health assessment looks at your individual risk and whether you’d benefit from a bone density scan or treatment.
Your heart
After the menopause, “bad” LDL cholesterol often rises and the risk of heart disease starts to catch up with men’s. Palpitations during perimenopause are common and usually harmless, but they deserve a proper check, particularly if they come with other symptoms.
Dr Ibrar Ahmed, our principal GP, has a specialist interest in heart health and a diploma in cardiology, so heart checks are a natural part of how we look after women at this stage. A blood pressure check, a cholesterol test and, where needed, an ECG give a clear picture of where you stand.
Getting the most from your appointment
Perimenopause is easier to diagnose and treat when your doctor has the full picture. Before your appointment:
- Keep a symptom diary for a few weeks. Note your periods, hot flushes, sleep, mood and anything else that feels different
- List your questions. For example: is this perimenopause? Is HRT right for me? Do I need any tests?
- Bring a list of medicines, including supplements
- Know your family history, especially of breast cancer, blood clots, heart disease and osteoporosis
- Think about what matters most to you. Is it sleep? Mood? Work? Your relationship?
Many first conversations about perimenopause work well by video. An online GP appointment lets you talk through your symptoms from home or work, and we can arrange blood tests or an in-person review if needed. Video appointments at OneMedicine start from £45.
If you’d rather be seen face to face, or you need an examination, an in-clinic private GP appointment gives you unhurried time to talk everything through. Our team also includes Dr Sarah Elhag, a GP with MRCGP membership.

Frequently questions our patients ask
What are the first signs of perimenopause?
Changes to your periods are often the first sign: they may come closer together, become heavier or lighter, or be skipped. Many women also notice poor sleep, low mood, anxiety or hot flushes in the early stages, sometimes before their periods change at all.
At what age do perimenopause symptoms usually start?
Most women notice perimenopause symptoms in their mid-40s, but they can start in the late 30s or early 40s. If you’re under 40 and your periods stop or change, see a doctor, as this may be premature ovarian insufficiency and needs proper assessment.
Can I get pregnant during perimenopause?
Yes. You can still ovulate during perimenopause, even if your periods are irregular. Contraception is recommended until two years after your last period if you’re under 50, or one year after if you’re over 50. HRT is not a contraceptive.
Is there a blood test for perimenopause?
For women over 45 with typical symptoms, a blood test usually isn’t needed to diagnose perimenopause, as hormone levels change from day to day. Blood tests are useful to rule out other causes, such as thyroid problems or anaemia, and to assess women under 45.
How long does perimenopause last?
Perimenopause lasts around four years on average, but it varies a lot. For some women it’s a few months, and for others it’s ten years or more. It ends when you reach the menopause, which is 12 months without a period.
