Symptoms, explained
121 plain-language explainers on what the perimenopause and menopause transition does and why. Every page cites its sources, says what it cannot know, and never sells or prescribes anything. For where you are in the transition, take the free self-check.
Where you are in the transition
When it starts, which stage you are in, and what counts as early.
When does perimenopause start? The honest answer
The age perimenopause typically begins, how long before your final period it starts, why symptoms appear while cycles are still regular, and what shifts the timing.
How long does perimenopause last?
Perimenopause lasts about four years on average, with a realistic range from a few months to eight or more. What decides where you fall in that range, and how you know it has ended.
The stages of menopause, and how to tell which one you are in
Premenopause, early and late perimenopause, menopause and postmenopause — what defines each stage under the STRAW+10 system and why the stage changes what helps.
Perimenopause at 35: possible, uncommon, and worth investigating
Whether perimenopause can start at 35, what else produces the same symptoms at that age, and why a hormone test is appropriate here when it would not be at 48.
Perimenopause at 45: squarely normal, and often dismissed anyway
Why 45 is the most typical age for perimenopause, what the first signs look like, and why guidance says no hormone test is needed to diagnose it at this age.
Early menopause: symptoms, what counts as early, and why it matters more
Menopause before 45 — how common it is, the symptoms, why it carries different long-term risks from menopause at 51, and what needs investigating.
Primary ovarian insufficiency: menopause before 40
What primary ovarian insufficiency is, how it is diagnosed, why it is not simply early menopause, and why hormone therapy is treated as replacement rather than optional.
Surgical menopause: why removing the ovaries hits harder
What happens when both ovaries are removed — why symptoms are more severe than natural menopause, the long-term risks of early oophorectomy, and what guidance says about hormone therapy.
Menopause after hysterectomy: how to tell when it happens
Why hysterectomy with ovaries retained brings menopause forward, how to recognise it without periods to track, and why hormone therapy afterwards is usually estrogen alone.
Postmenopause: what changes once the transition is over
What postmenopause means, which symptoms fade and which continue or worsen, and what becomes worth monitoring once periods have stopped for good.
Perimenopause symptoms checklist: what to take to an appointment
A structured list of perimenopause symptoms by system, what to record before an appointment, and which items change the consultation when mentioned explicitly.
Hormones, periods and bleeding
What each hormone does, and every way the cycle changes.
Low estrogen symptoms: what falling estrogen actually feels like
The symptoms of low estrogen, from hot flashes and night sweats to joint pain, dry skin and brain fog — and why a single blood test rarely settles it.
Low progesterone symptoms: the first hormone to fall
Progesterone falls before estrogen does in perimenopause. The symptoms linked to it — shorter cycles, heavier periods, worse sleep, more anxiety — and what the evidence actually supports.

Why progesterone falls before estrogen in perimenopause, what that explains about symptoms, and the difference between progesterone and synthetic progestogens.

What estradiol testing shows through the menopause transition, why a single result rarely settles anything, and the few situations where measuring it genuinely helps.

How periods change through perimenopause — shorter cycles, skipped months, heavier bleeding — which patterns are expected and which need assessing.
Irregular periods in perimenopause: what's normal, what isn't
Cycle changes are how perimenopause announces itself. What typical irregularity looks like stage by stage, which bleeding patterns need prompt attention, and why contraception still matters.

Why perimenopausal bleeding becomes heavy, how to judge whether yours counts as heavy, the iron deficiency that follows, and what treatment options exist.
Spotting in perimenopause: what's hormonal and what needs a look
Light bleeding between periods is common as cycles become anovulatory in perimenopause — and it is also the symptom clinicians take most seriously. The patterns that are typical, and the ones that need assessment.
Periods every two weeks in perimenopause: what is going on
Why cycles shorten dramatically in perimenopause, when bleeding every two weeks is expected variation, and when it needs investigating.

Why period pain often worsens in perimenopause, why cramps happen in months with no bleeding at all, and what else causes pelvic pain at this age.
Postmenopausal bleeding: why this one always gets investigated
Any bleeding after twelve months without a period needs assessment. What causes it, how likely cancer actually is, and what the investigation involves.
Bleeding after sex in perimenopause and after menopause
Why bleeding after sex happens as estrogen falls, why it is usually fragile tissue rather than anything sinister, and why it is always examined anyway.
