Your Body

Perimenopause and menopause, properly explained

Most women arrive at perimenopause knowing three things about it: hot flushes, periods stopping, and something vaguely worrying about HRT. That leaves out the years of erratic hormones beforehand, the symptoms nobody links to hormones at all, and the fact that the treatment picture has changed substantially since the headlines that frightened a generation. This guide covers what is actually happening in your body, what the full range of symptoms looks like, what your options genuinely are, and how to be taken seriously when you ask for help.

💭

Sound like you?

Any of these can be hormonal, and many women are told they are not.

🌙You wake at three every morning, drenched, heart going, unable to get back to sleep.
🌀Anxiety has arrived from nowhere in your forties, and rage is far closer to the surface than it used to be.
🧠You lose words mid sentence and have started to genuinely worry about your memory.
🩹Your joints ache, your skin itches, your periods are unrecognisable, and none of it seems connected.

💜You are not losing your mind and you are not too young. This is an endocrine event, and it is treatable.

01

Know which stage you are in

Perimenopause is the run up, when hormones swing erratically and periods change but have not stopped. Menopause itself is a single point: twelve consecutive months with no period. Everything after that is postmenopause. Perimenopause is where most symptoms live and it commonly lasts several years, which is why women are so often treated too late.

02

Track symptoms before you see anyone

Write down dates, bleeding pattern, sleep, mood, temperature, joints, brain fog and libido for two or three months. Appointments are short and symptoms are easy to dismiss one at a time. Presented together as a pattern, they are much harder to attribute to stress or to simply being busy.

03

Understand why blood tests often are not the answer

In perimenopause, hormone levels swing so much week to week that a single blood test can look entirely normal while you feel terrible. For women over forty five, diagnosis is usually made on symptoms alone. Tests matter more if you are younger, if your periods have stopped early, or if something else needs ruling out.

04

Ask about the whole range of treatment

Hormone therapy, vaginal oestrogen, testosterone where appropriate, non-hormonal medication, and cognitive behavioural therapy for flushes and sleep are all legitimate options with different roles. They are not alternatives to each other so much as different tools, and many women end up using more than one.

05

Protect the long game, not just today

Falling oestrogen affects bone density and cardiovascular health, not only how you feel. Strength training, enough protein, vitamin D, not smoking and keeping blood pressure in check all matter more from here than they did before. This is the part of menopause care that gets the least attention and pays off for decades.

You are not declining. You are changing, and everything you have learned so far comes with you.

Getting taken seriously

Being dismissed is common. These three things change the odds.

06

Lead with the word, and with function

Say "I think this is perimenopause" and then describe what you can no longer do: the work you are getting wrong, the sleep you are not getting, the sex that now hurts. Functional impact moves clinicians in a way that a list of feelings often does not, and it also helps if you need to escalate.

07

Ask for the reasoning, and ask again

If you are told no, ask what the specific reason is and whether it is recorded. Menopause care is uneven, and a polite request for a second opinion or a referral to a menopause specialist service is entirely reasonable. Bringing printed NHS or British Menopause Society guidance is not rude, it is useful.

08

Do not accept vaginal symptoms as permanent

Dryness, soreness, urinary urgency and recurrent infections are extremely common, they get worse rather than better if untreated, and local vaginal oestrogen treats them directly. It is a different treatment from systemic HRT with a different risk profile, and a great many women are never told it exists.

🧰Your menopause tool kit

A symptom and cycle diary, kept for two or three months. Pattern beats anecdote in a ten minute appointment, and it also shows you what is actually improving once treatment starts.
Cool sleep conditions. Layers you can throw off, a fan, cotton rather than synthetics, a cold drink within reach. Night sweats are miserable partly because of the wakefulness they cause, so protecting sleep protects mood.
Strength training twice a week, however small the weights. Muscle and bone both respond to load, and this is the single most protective habit available for the decades after menopause.
Women's Health Concern, the patient arm of the British Menopause Society, for free evidence based factsheets you can take to an appointment.
The Daisy Network if your periods stopped before forty, which is premature ovarian insufficiency and needs different, more proactive care.

✨Try this: the one page appointment sheet

Take one sheet of paper to your GP. On it, write:

  1. Your age, your last period, and how your bleeding pattern has changed.
  2. Your five worst symptoms, ranked, with how long each has been going on.
  3. One line on what you can no longer do properly because of them.
  4. What you are asking for, in plain words, and one question you want answered.
  5. Any relevant history: blood clots, breast cancer, migraine, blood pressure, other medication.

Hand it over at the start rather than talking through it. It makes the appointment about the decision rather than about establishing that something is wrong, which is where most of the ten minutes otherwise goes.

Going deeper: what is actually happening, and what the evidence says now

Menopause is one of the most misreported areas of women's health. Understanding the biology and the history of the headlines makes the decisions much clearer.

Why perimenopause feels worse than menopause

People assume hormones decline in a tidy line. They do not. As the ovaries become less responsive, the body compensates by pushing harder, so oestrogen in perimenopause swings unpredictably, sometimes reaching levels higher than in your thirties, sometimes dropping sharply within the same month. Progesterone falls earlier and more steadily as ovulation becomes less reliable.

Hormone levels before, during and after perimenopause A line chart across three labelled stages. In the reproductive years the line rises and falls in a regular repeating monthly rhythm. In perimenopause the line becomes erratic with large unpredictable peaks and troughs. After menopause the line settles low and flat. A note says most symptoms occur during the erratic middle stage. Oestrogen does not decline in a straight line reproductive years regular monthly rhythm perimenopause erratic, unpredictable postmenopause low and steady oestrogen most symptoms belong to the erratic middle stage, not the flat one at the end
This is why symptoms come and go, why you can feel fine for a fortnight, and why one blood test proves very little.

Oestrogen receptors are not confined to the reproductive system. They are present in the brain, blood vessels, bone, joints, skin, bladder and gut. That is why the symptom list is so long and so strange: erratic oestrogen is not causing several separate illnesses, it is one signal changing in many places at once. And it is also why symptoms often settle in postmenopause, once levels are low but stable, rather than continuing to worsen forever.

The symptoms nobody connects to hormones

Hot flushes and night sweats are the famous ones and they are genuinely common. But the symptoms that most often go unrecognised are the ones that do not sound gynaecological at all: new or much worse anxiety, low mood, irritability and rage, difficulty finding words, poor concentration and memory lapses that feel frightening, disrupted sleep independent of sweating, joint and muscle aches, palpitations, dizziness, tinnitus, dry or itchy skin, burning mouth, headaches or worsening migraine, recurrent urinary infections, urgency, vaginal dryness and painful sex, loss of libido, and weight redistribution around the middle.

Women commonly get treated for each of these separately, and in particular are often offered antidepressants for what is a hormonal picture. Antidepressants have a real place, especially where there is depression or where hormone therapy is not suitable, but they are not the first line treatment for menopausal symptoms in someone whose low mood arrived alongside erratic periods and night sweats. If that is the offer and it does not fit, it is fine to say so and ask about hormone therapy specifically.

HRT, and the headlines that frightened a generation

In 2002 a large American trial reported findings that were widely covered as showing hormone therapy caused breast cancer and heart disease. Prescribing collapsed internationally, almost overnight. What was much less widely reported was that the average participant was well past the age at which women typically start treatment, that many were years beyond menopause, that the formulations used are not the ones most commonly prescribed in the UK now, and that later re-analysis found the picture depends heavily on age, timing, type and how long it is taken.

The current position, in broad terms, is this. For most women under sixty, or within ten years of menopause, who have troublesome symptoms and no specific contraindication, the benefits of hormone therapy generally outweigh the risks. Risks are not zero and they differ by preparation: oestrogen given through the skin as a patch, gel or spray does not carry the clot risk associated with tablets, and the breast cancer risk relates mainly to the progestogen component and to duration, is small in absolute terms for most women, and sits alongside risks from things like alcohol intake that receive far less attention. If you have had breast cancer, certain clotting disorders or some other specific conditions, systemic hormone therapy may not be suitable, and that is a conversation for a specialist rather than a closed door.

Two things are worth separating out. First, local vaginal oestrogen used for dryness and urinary symptoms works very differently from systemic HRT, is absorbed minimally, and is generally considered suitable for far more women, including many who cannot take systemic treatment. Second, "bioidentical" is used to mean two different things: body identical preparations, which are regulated, licensed and routinely prescribed on the NHS, and compounded bioidentical hormones sold by private clinics, which are unregulated, unlicensed and not recommended by UK menopause specialists. The words sound the same and the two are not.

The words worth knowing

Perimenopause. The transitional years of erratic hormones and changing periods before they stop. Where most symptoms happen, and commonly several years long.
Menopause. Technically a single point in time, twelve months after your last period. Everything after it is postmenopause.
Premature ovarian insufficiency. Ovarian function stopping before forty. Needs treatment for bone and heart protection, not just symptom relief, so it is managed differently.
Surgical menopause. Menopause caused abruptly by removal of the ovaries. Symptoms typically arrive fast and hard because there is no gradual transition.
Genitourinary syndrome of menopause. The umbrella term for vaginal dryness, soreness, painful sex and urinary symptoms. Progressive if untreated, and very responsive to local oestrogen.
Body identical versus compounded bioidentical. The first is regulated and NHS prescribed. The second is unlicensed, sold privately, and not recommended by UK specialists.
Vasomotor symptoms. The clinical term for hot flushes and night sweats. Useful to know because it appears throughout guidance and prescribing information.

Three things that get overstated

The belief You are too young for this if you are in your early forties or still having periods.
Closer to the truth Perimenopause commonly starts in the forties and sometimes earlier, and by definition you are still having periods during it. Being told you are too young while your periods are changing and you cannot sleep is a reason to ask again, or ask someone else, not a reason to wait.
The belief HRT causes breast cancer, so it should be avoided if at all possible.
Closer to the truth Risk depends on age, timing, preparation and duration, it is small in absolute terms for most women who start near menopause, and it has to be weighed against the benefits for symptoms, bone and quality of life. It is a personal calculation to make with a clinician who knows the current evidence, not a blanket rule.
The belief The brain fog means early dementia, and the mood changes mean you have developed a mental illness.
Closer to the truth Cognitive symptoms in perimenopause are real, well recognised, and for most women improve as hormones stabilise or with treatment. That is not a reason to ignore genuine concerns about memory or serious low mood, both of which deserve proper assessment, but hormones should be on the list of explanations rather than left off it.

Work, relationships, and the bit that is not medical

Menopause arrives, on average, at the point where many women are managing senior responsibility, teenagers and ageing parents at the same time. Symptoms that would be manageable in isolation land in the middle of all of that, which is why so many women quietly reduce their hours or leave work altogether. In the UK, menopause is not a protected characteristic in its own right, but symptoms can amount to a disability, and unfavourable treatment because of them can amount to sex, age or disability discrimination. Many employers now have menopause policies, and reasonable adjustments such as flexible hours, a fan, uniform changes, a cooler workspace or rescheduled meetings are usually straightforward to ask for.

Relationships take a hit too, particularly where painful sex and lost libido go unexplained. Saying the word out loud to a partner, and treating the physical symptoms properly rather than enduring them, resolves more of this than couples expect. And if low mood has tipped into something that frightens you, that is worth urgent help rather than patience: your GP, NHS 111, or Samaritans on 116 123, free and at any hour.

Why this actually helps

Most of the distress around perimenopause is not caused by the symptoms alone, it is caused by not knowing what is happening. Women spend years believing they are becoming anxious, unreliable, forgetful or simply diminished, when what is actually happening is an identifiable and treatable endocrine transition. Knowing the stages, recognising the full symptom list, understanding what the evidence on treatment actually says, and having the language to ask for it turns a frightening personal decline into a medical situation with options. That shift alone tends to make everything else more bearable.

If your periods stopped before you were forty, that is premature ovarian insufficiency and needs proactive treatment for your bones and heart as well as your symptoms, so ask for a referral. Women's Health Concern and The Daisy Network both offer free, evidence based information. And any bleeding after a full year without periods should always be checked by a GP.

Understand it

Erratic oestrogen, not steadily falling oestrogen, is what drives the perimenopausal years. Because oestrogen receptors sit throughout the body, one changing signal produces symptoms that look unrelated to each other.

Symptoms commonly missed as hormonal:

  • New anxiety, rage or low mood in your forties.
  • Losing words, poor concentration, frightening memory lapses.
  • Joint and muscle aches, itchy skin, palpitations.
  • Waking at three or four every morning.
  • Recurrent urinary infections and urgency.
  • Painful sex, dryness and lost libido.

In real life

A woman of forty four is treated for anxiety for two years, then for a frozen shoulder, then for recurrent cystitis, before anyone joins the three together with the fact that her periods have become unrecognisable.

Other ways this shows up:

  • A normal blood test used to rule out perimenopause, when levels swing week to week.
  • Antidepressants offered first for symptoms that arrived with night sweats.
  • Vaginal dryness endured for years without anyone mentioning local oestrogen.
  • Quietly dropping hours at work rather than asking for adjustments.
  • One small thing to try: track symptoms and bleeding for three months before your appointment.
  • Another thing worth trying: two short strength sessions a week, starting now.
