Where does the list of 34 symptoms of perimenopause come from?
Nowhere official. The number is a content convention that spread between commercial menopause sites by mutual citation; no NHS page, no NICE guideline and no British Menopause Society document contains a list of 34.[1][4] UK sources group symptoms by domain and never count them.

That absence explains the variants. Split "changes to your periods" into heavier, lighter, more frequent and less frequent and the count rises; merge them and it falls. The list is a way of saying "a lot of things change at once", and it is worth reading as that rather than as a diagnostic instrument.
What the NHS actually lists instead of 34 symptoms
Eight groups, and 38 named entries inside them — 36 of them distinct, because anxiety and palpitations each appear under two headings. The NHS symptoms page is the closest thing the UK has to an official inventory, and it is organised by where in the body a change shows up rather than by a running total.[1]
| NHS group | Changes named | Count |
|---|---|---|
| Changes to your periods | More frequent, less frequent, heavier, lighter, eventually stopping | 5 |
| Hot flushes and night sweats | Hot flushes, night sweats, heavy sweating, palpitations, anxiety, dizziness | 6 |
| Sleep problems | Trouble getting to sleep, trouble staying asleep, irritability, stress, anxiety | 5 |
| Mood changes, poor memory and brain fog | Mood swings, low mood, depression, memory problems, concentration problems | 5 |
| Weight gain | Weight gain around the stomach and upper body | 1 |
| Vaginal problems | Dryness, burning, irritation, itching, painful sex | 5 |
| UTIs | Pain or burning when passing urine, needing to go more often | 2 |
| Other symptoms | Palpitations, loss of bone density, urinary incontinence, worse headaches and migraines, muscle and joint aches, hair thinning or loss, skin changes, reduced libido, dental and gum problems | 9 |
Source: NHS, Symptoms of menopause and perimenopause.[1] Groups and wording are the NHS's; the counts are ours, taken by counting the changes named under each heading. The eight rows total 38 entries and 36 distinct changes — anxiety and palpitations are each named twice.
What the 34 symptoms of perimenopause list cannot do
It cannot diagnose anything, and it cannot be treated with a supplement. NICE says perimenopause is identified in people aged 45 or over without any laboratory test, from recently started vasomotor symptoms plus a change in the menstrual cycle.[4] A checklist ticked at home skips the part where a GP rules out the other conditions that produce the same changes.
Food supplements are not medicines and do not treat symptoms.[8] The only claims a UK label may carry are the per-nutrient ones on the Great Britain register. Vitamin B6 contributes to the regulation of hormonal activity, and vitamin D and vitamin K contribute to the maintenance of normal bones.[7] Those are general nutrition claims that apply to everyone. None of them refers to menopause or perimenopause, and none may be presented as addressing any change on this list.
Treatment is a GP conversation, not a checklist outcome. The NHS puts HRT first, with oestrogen as its main type, sometimes given as a cream or pessary for vaginal dryness and urinary symptoms. Progestogen is added to protect the womb if there has been no hysterectomy.[3]
Where HRT is unsuitable or unwanted, the NHS names cognitive behavioural therapy for hot flushes and night sweats, with clonidine or an antidepressant if that does not help.[3]
Botanicals hold no authorised claim at all. The NHS goes further on two of the commonest. Red clover and black cohosh are sometimes sold for menopause symptoms, but there is very little evidence for how well they work or how safe they are. Some can also interact seriously with other medicines.[3]
What are odd signs of perimenopause?
Dental and gum problems, dry itchy skin and a more noticeable heartbeat are the three that surprise people most, and all three sit in the NHS's own "other symptoms" list of nine.[1] The same list includes urinary incontinence, worse headaches and migraines, muscle and joint aches, hair thinning and reduced libido.
The remaining entries in that group are palpitations, loss of bone density, skin changes including dry and itchy skin, and urinary incontinence.[1] None of them is unusual in itself; they are unexpected only in this context.
They read as odd because the popular version of the story is hot flushes and nothing else. Perimenopause is the run of fluctuating hormones before periods stop, and any tissue that responds to oestrogen can register that fluctuation — which is why the NHS inventory runs from gums to joints.
How do you tell what stage of perimenopause you are in?
By your periods, not by a test. NICE's marker for perimenopause is vasomotor symptoms that have recently started together with any change in the menstrual cycle. Menopause itself is the point at which you have had no period for 12 consecutive months and are not using hormonal contraception.[4] Everything after that is postmenopause.[1]
Hormonal contraception blurs the picture, because it removes the bleeding pattern the diagnosis relies on. NICE flags that difficulty explicitly and advises against using an FSH blood test in anyone taking combined oestrogen and progestogen contraception or high-dose progestogen.[4]

How can I test myself for perimenopause?
You cannot, and past 45 you should not need to. NICE names six tests that must not be used to identify perimenopause or menopause in people aged 45 or over:[4]
- anti-Müllerian hormone
- inhibin A
- inhibin B
- oestradiol
- antral follicle count
- ovarian volume
An FSH blood test has a narrow role. NICE says to consider it only in people aged 40 to 45 who have menopause-associated symptoms including a cycle change, and in people under 40 in whom menopause is suspected.[4] A home kit sold as a perimenopause test is measuring a hormone that fluctuates by the week.
What are the 40 symptoms of perimenopause?
The same list with the splitting done more finely. Perimenopause is the run of fluctuating hormones before periods stop, and the NHS describes it in eight groups holding 38 entries.[1] Separate "headaches and migraines" into two, split "hair thinning or hair loss" into two, and 40 arrives without a single new symptom being discovered.
The reverse works just as easily. Fold the four ways a period can change into a single line and 38 becomes 35. Merge "irritation" and "itching" in the vaginal group and you are at 34 — the number in every headline. Neither 40 nor 34 has a clinical document behind it, and a count published without saying what was counted is decoration.
What are the 33 symptoms of perimenopause?
A tighter cut of the same checklist, usually the 34 with one entry folded into another. Working from the NHS's eight groups and 36 distinct changes, merging any three overlapping pairs gets you there, and merging two gets you to 34.[1]
The three figures circulate together because none of them descends from a UK clinical document. The NHS describes the changes by domain, NICE identifies perimenopause from vasomotor symptoms plus a cycle change, and neither totals anything.[1][4] The useful question is not how many there are but which ones you have and for how long.
What age does perimenopause usually start?
Late thirties or early forties, according to Women's Health Concern, the patient arm of the British Menopause Society.[5] Menopause itself arrives for most people between 45 and 55, and before 40 it is classed as premature ovarian insufficiency.[5][2]
The stretch in between is longer than most people expect. The NHS puts symptom duration at 7 to 9 years, and sometimes longer.[1] In the SWAN cohort the median total duration of frequent hot flushes and night sweats was 7.4 years across 1,449 women. For those whose flushes began while they were still premenopausal or early perimenopausal, the median rose above 11.8 years.[6]
- No NHS page, NICE guideline or British Menopause Society document contains a list of 34 symptoms.
- The NHS names 38 entries across eight groups — 36 distinct, since anxiety and palpitations appear twice — including a nine-item "other symptoms" list.
- NICE identifies perimenopause at 45 or over with no laboratory test, and names six tests that must not be used.
- Women's Health Concern puts the start in the late thirties or early forties; menopause itself is 12 consecutive months with no period.
- Symptoms usually last 7 to 9 years; SWAN's median for frequent hot flushes and night sweats was 7.4 years in 1,449 women.
None of the 34-symptom lists is a diagnosis. A supplement is food, not a treatment, and nothing here replaces a GP conversation or HRT. If you are looking at what a UK label may honestly say, our menopause support gummies print every botanical amount openly and carry only authorised nutrient wording. The rest of our gummy vitamins range is built the same way.
