Perimenopause isn't just one or two symptoms. Health services now list a wide range, from hot flashes, joint pain and brain fog to mood changes, sleep problems and changes to your periods. Many women have a combination of them, often years before their periods stop, and it can be hard to connect the dots. You're not imagining it, and you're not broken. If you're 45 or over, perimenopause is usually recognized from your symptoms and changes in your cycle, without a blood test.

Which symptoms can actually belong to perimenopause? This article is the full map — 25 symptoms across seven areas of your body and mind, and why so many women never connect them. If you want to know how it usually starts, read the first signs of perimenopause; if your periods have already stopped, what changes after menopause picks up the story from there.

Joint pain that seems to come out of nowhere. Waking at 3 a.m. for no reason and lying there, wide awake. Walking into a room and forgetting why. Snapping at someone you love over something so small you feel embarrassed five minutes later. On their own, each of these is easy to put down to stress or age, and many women never connect them. That's exactly why this map exists.

So what actually counts as a perimenopause symptom?

There is no official list with a fixed number. Changes to your periods and hot flashes are the best-known signs, but health services also list sleep problems, mood changes, brain fog, joint and muscle aches, headaches, palpitations, skin and hair changes, and vaginal and urinary symptoms.

Here's the honest answer: more than most people think. For a long time, the list was short. In 2005, a US National Institutes of Health panel concluded that hot flashes, night sweats and vaginal dryness were clearly tied to the menopausal transition, with some evidence for sleep disturbance — and noted how difficult it is to separate menopause symptoms from those of ageing. Today, the NHS describes a much wider picture: changes to your periods, hot flushes and night sweats, sleep problems, mood changes, poor memory and brain fog, vaginal and urinary symptoms, palpitations, headaches, muscle aches and joint pains, hair thinning, dry and itchy skin and a lower sex drive.

And it shows up differently in every woman. A 2024 review of the global picture of perimenopause points to considerable variation in how women experience cognitive issues, mood changes, sleep disturbances, urogenital symptoms, muscle and joint pain and changes in libido. The NHS puts it simply: some women have symptoms that have a big impact on daily life, others hardly have any.

This article groups the symptoms health services describe, and those women commonly report, into seven areas:

Hot flashes, skin and hair: hot flashes, dry skin, hair thinning

The classic ones, and usually the first thing people associate with "the change." The NHS describes hot flushes as your face, neck and chest suddenly feeling very hot or cold, sometimes with sweating, palpitations, anxiety or dizziness.

Physical: joint pain, headaches, heart palpitations, breast tenderness, bloating

These symptoms are often not linked to perimenopause. Joint pain, headaches and palpitations are on the NHS list; breast tenderness and bloating are things many women describe, but they can also have other causes, so they're worth mentioning to your doctor if they're new or don't settle. If joint pain is your main concern, Can Menopause Cause Joint Pain? looks at why it happens and when to get it checked.

Cognitive: brain fog, word-finding trouble, dizziness, concentration problems, memory lapses

If you've ever stood in a doorway with absolutely no idea why you walked in there — you're in good company. The Menopause Society notes that 40 to 60 percent of midlife women report cognitive symptoms such as forgetfulness during the menopause transition, including difficulty remembering words and names and trouble concentrating. For more on why it happens and what can help, see our article on brain fog during menopause.

Mood: anxiety, restlessness, low motivation, a drop in self-confidence

The NHS lists mood swings, low mood and depression among perimenopause symptoms, and notes they may feel worse when you're sleeping badly and very tired. If low mood doesn't lift, talk to your doctor. If you ever have thoughts of harming yourself, call your local emergency number, or find a free, confidential helpline in your country at findahelpline.com.

Sleep-related: poor sleep quality, drowsiness, appetite changes (more or less hungry than usual)

If you are struggling with night waking, you can read our guide on why you may wake up at 3 a.m. during perimenopause.

Intimate: vaginal dryness, urinary urgency

This category deserves its own article, so we don't go deeper into it here.

Cycle-related: periods arriving early, lighter (or heavier) bleeding, or sometimes no period at all that month

That last one trips a lot of women up, because "no period" doesn't feel like a symptom — it feels like nothing happened. But in perimenopause, nothing happening is often the something. The Menopause Society describes cycles often becoming a little shorter early on, bleeding that may be heavier or lighter, and skipped periods later in the transition.

That's 25 symptoms, and here's the part that matters most: you don't need all of them, and you don't need them constantly. Many women get a changing handful, and the NHS notes that symptoms can change over time — hot flushes may ease and be replaced by others, such as low mood and anxiety. Because some of these symptoms can also have other causes, anything new, severe or worrying is still worth checking with your doctor.

Why Did Nobody Tell You About This Sooner?

Partly because the best-known symptoms are hot flashes and missed periods, so sleep, mood, memory and joint changes are easy to put down to stress or age. And there's no single blood test that confirms perimenopause, so it has to be recognized from your symptoms and your cycle.

Sleep is a good example of how the disconnect happens. A 2018 review describes the menopausal transition as being associated with an increase in insomnia symptoms, especially difficulty staying asleep — and yet many women are handed sleep hygiene tips with no mention of why their nights suddenly feel different. You get told to put your phone away an hour before bed. Nobody mentions hormones.

Cognitive symptoms have the same problem. Forgetting words or losing your train of thought in your forties can be frightening. The Menopause Society says brain fog during perimenopause is very common, that changes in cognitive performance are typically mild and within the limits of normal, and that dementia at midlife is very rare. If a symptom feels severe, sudden or frightening, talk to a doctor about it.

The bigger issue: there's no single blood test that hands you a tidy diagnosis. Guidance from the UK's NICE says that in otherwise healthy women aged 45 or over, perimenopause should be identified without laboratory tests — based on recently started hot flashes and any changes in the menstrual cycle. Which means the noticing often starts with you. Nobody is going to hand you a chart. It helps to learn to read your own.

What Should You Take Away From This?

Being able to name your symptoms can make them feel less frightening and easier to talk about. Keeping simple notes of what you feel and when can help you and your doctor see what's going on.

No single breathing exercise fixes every symptom on this list, and "you've got this" is not a strategy. But once you can name what's happening, it stops being a shapeless, scary fog and becomes something you can actually talk about. A joint ache can have a reason. A 3 a.m. wake-up can have a reason. Forgetting why you walked into a room is very common in perimenopause — and if memory problems worry you, that's a good reason to see your doctor, not to panic.

Tracking your symptoms — intensity, frequency, what came before and after — can help you see whether something keeps coming back or was just a bad week, and it can make conversations with your doctor more concrete. That's what the Menoup app is for: logging these shifts day to day. Mona, the app's AI companion, can help you look at those patterns and share general, evidence-informed information—it isn't a substitute for advice from your doctor.

You're not falling apart. You're going through a stage of life that, for some reason, we still don't talk about enough. Let's change that one honest article at a time.

Frequently Asked Questions

At what age does perimenopause usually start?

Cleveland Clinic says perimenopause usually starts in your mid-40s, but it can start earlier. The NHS notes that menopause usually happens between 45 and 55.

How do I know if my symptoms are from perimenopause?

If you're 45 or over and have recently started hot flashes alongside changes in your cycle, NICE guidance says that's how perimenopause is usually identified. But many of these symptoms can also have other causes, so the best way to know is to talk them through with your doctor.

Is there a blood test for perimenopause?

Not a single reliable one. NICE advises that perimenopause in women aged 45 or over is identified from symptoms and cycle changes, without laboratory tests. In younger women, or in some special situations, a doctor may consider hormone blood tests.

How many symptoms of perimenopause are there?

There's no official number. The NHS lists more than a dozen, from period changes and hot flushes to brain fog, joint pain and skin changes. This article maps 25 that women commonly describe, grouped into seven areas.

When should I see a doctor about perimenopause symptoms?

The NHS advises contacting your GP if you think you have perimenopause symptoms and want to know your options, if you have palpitations, if you're bleeding more rather than less than before, or if you have any vaginal bleeding after 12 months without a period.
