Perimenopause: The transition, not the destination

Perimenopause is a hormonal shift that usually runs for several years, and longer the earlier it starts. Here is what the evidence says about symptoms, tests, lifestyle and HRT, and what you can safely ignore.

The short answer

Perimenopause is the run-up to menopause, the years in which your hormones swing and your periods start to change. Most women notice the first changes in their mid to late 40s, and the transition usually lasts several years, longer the earlier it starts.[14, 24] From age 45, doctors diagnose it from symptoms and cycle changes alone, without lab tests, because a single hormone result proves little.[11] Up to about 80 percent of women get hot flashes and night sweats,[13] and in the SWAN study frequent ones lasted 7.4 years or more for half of those women.[5]

What is perimenopause, and how is it different from menopause?

Perimenopause is the run-up to menopause: the years of change before your final period, when your ovaries work more and more erratically.[1] Menopause itself is a single date, your final period, and you only know it looking back, once 12 months have passed without bleeding.[1] Perimenopause ends when those 12 months are up. Postmenopause starts from the final period itself, so the first year after it counts as both.[1]

Doctors split those years into stages with STRAW+10, the international staging system for reproductive aging. The table shows what each stage means and how it tends to feel.[1]

Stage What it means How you notice it
Late reproductive stage Cycles still regular.[1] Flow or cycle length shifts a little
Early perimenopause Cycle length keeps differing by 7 or more days from one cycle to the next[1] First hot flashes, sleep changes
Late perimenopause Gaps of 60 or more days between periods[1] Hot flashes likely[1]
Menopause Your final period Confirmed only after 12 months without a period[1]
Postmenopause Everything after the final period[1] Hot flashes most common in the first years, often longer[1, 5]

One word you will not find in the table is "premenopause". People use it both for all the years before menopause and for the phase just before perimenopause, so STRAW+10 avoids it. Its name for that regular-cycle phase is the late reproductive stage[1]

The transition itself usually begins in the mid to late 40s,[14] and how long it lasts depends on when it starts. The SWAN study followed a mixed group of US women over many years. Women who started late typically took about 4 years to reach their final period, while women who started young took about 8 to 9 years.[24]

Symptoms can outlast the transition. In SWAN, half of the women with frequent hot flashes still had them after 7.4 years.[5] The typical woman went on having them for 4.5 years after her final period.[5] So the popular image of menopause as a brief inconvenience is off by several years. For many women it is closer to a life chapter than a season.

A chapter that long is a normal hormonal transition, often a demanding one, but not a disease or a deficiency to fix. Some women barely notice it, while for others the symptoms disrupt work, sleep or relationships, and both are normal. Normal does not mean you have to sit it out, though. Knowing your stage helps your doctor read a symptom, which can mean different things at 43 with regular periods than at 51 after a year of skipped ones.

Perimenopause symptoms: which ones actually show up?

The most common perimenopause symptoms are hot flashes and night sweats, disrupted sleep, mood changes, brain fog, vaginal and urinary changes, and joint aches. Hot flashes and night sweats (doctors call them vasomotor symptoms) affect up to about 80 percent of women.[13] The mix varies between women and over time, so it helps to map your own pattern with our menopause symptom checker before you see a doctor.

Hot flashes range from background warmth to drenching night sweats, and the night-time ones are where sleep comes in. In one experiment, researchers used a drug to switch off ovarian hormones for a while in healthy women who had not reached menopause. The hot flashes that followed cut the share of time in bed the women actually spent asleep, which points to a causal link.[18] Insomnia can also come without any night sweats, as early waking, racing-mind nights or lighter sleep, so treating hot flashes does not always fix sleep.

Mood needs the same attention as sleep. In SWAN, major depression was two to four times more likely during perimenopause and early postmenopause than before it.[28] That held both for women who had been depressed before and for those who had not. Because the finding comes from watching women over years, it shows a link rather than proof that hormones alone cause it. Still, low mood in this window deserves a doctor's view rather than self-diagnosis. If your mood feels out of proportion to your circumstances, or a low patch lasts for weeks, talk to your GP, Hausärztin or Frauenärztin instead of waiting.

Memory complaints follow a gentler arc. Normally, people score better each time they repeat a memory or processing-speed test, because they learn from the practice. In SWAN, women in perimenopause lost that usual improvement, and it came back after menopause.[6] The brain fog is therefore real and, in this study, temporary. If memory problems keep getting worse or do not ease after menopause, get them checked.

Vaginal and urinary changes get the least airtime of all, even though vaginal dryness, recurrent urinary tract infections, urgency and pain during sex are common. They tend to become more frequent in the years after menopause.[1] and, unlike hot flashes, usually do not go away on their own. Vaginal estrogen treats them locally, though symptoms often return when it is stopped[11]

None of the signs in this section proves perimenopause on its own. Only together with changes in your cycle do they form a picture.

What changes in your hormones, heart, bones and brain?

The defining hormonal feature of perimenopause is volatility rather than a steady decline. The hormone doctors usually look at is FSH (follicle-stimulating hormone), the signal your brain sends to your ovaries. In the early transition, FSH is raised but variable.[1] In the late transition, levels swing so widely that FSH can sit in the menopausal range one month and in the normal range the next.[1] Those normal-looking readings often come when estradiol, the main form of estrogen, runs high.[1]

That swing is why one hormone result says little on its own. From 45, doctors diagnose perimenopause from symptoms and cycle changes without lab tests.[11] Between 40 and 45, or under 40, an FSH blood test can help when early menopause is suspected.[11]

Your blood fats change around the same time. In SWAN, total cholesterol, LDL cholesterol and apoB (a count of the particles that carry cholesterol) rose sharply in the year around the final period.[16] Blood pressure, blood sugar, insulin and inflammation markers showed no such jump, because they drifted slowly over the years or did not change at all.[16] HDL, the so-called good cholesterol, rises as well, but its particles seem to protect less well.[15] That jump in blood fats is the part tied to menopause itself, which makes a cholesterol check around this time a sensible step.

Bone follows a similar timetable. In SWAN, bone density at the spine and hip started dropping about one year before the final period and fell fastest until two years after it.[17] About 7 percent of spine density went in that window alone.[17] That makes the transition a good time to start bone-loading exercise, which still helps after an osteoporosis diagnosis.[7]

The brain changes during the same years. A brain-imaging study compared women before, during and after menopause and found differences between the stages in brain structure, connectivity and energy use.[8] Grey-matter volume and some energy measures looked more favourable after menopause than during perimenopause.[8] Most of these comparisons, though, were between different women rather than the same women followed over time. Only a small follow-up of 17 postmenopausal women two years later tracked the same people, and it found grey matter growing again in one memory-related region.[8] So the study suggests, but does not prove, a brain-level explanation for brain fog.

What helps with perimenopause? Lifestyle with real evidence

The best-supported lifestyle measures in perimenopause are progressive strength training for bone and muscle,[7, 25] backed by enough protein.[30] For long-term sleep problems, the treatment with evidence is cognitive behavioural therapy for insomnia (CBT-I),[29] and for heart health it is a Mediterranean-style diet.[31] Supplement stacks and "natural HRT" products do not have that kind of support, and The Menopause Society does not recommend herbal remedies or supplements for hot flashes.[13]

Strength training

The key trial on bone, LIFTMOR, tested heavy training in the very women usually told to avoid heavy loads.[7] It enrolled 101 screened, otherwise healthy postmenopausal women with low bone mass. For eight months, about half of them did closely supervised 30-minute sessions of heavy lifting and jumping twice a week, while the rest followed a light home programme. In the heavy-training group spine density rose and hip density held steady, while the home group lost some.[7] Only one minor injury was reported, a lower-back spasm.[7] If you have osteoporosis, a past fracture or back pain, start this kind of training with a physiotherapist or qualified coach, not alone.

LIFTMOR did not include women in perimenopause. A small Canadian pilot trial, STOP-EM, tested supervised heavy strength and impact training in women aged 45 to 60 who were in or just past perimenopause. After nine months they had more muscle, more strength and slightly higher spine density than a waiting-list group. With 40 women it was a feasibility study, a test of whether a bigger trial can work, so a larger trial still has to confirm the result.[25] Until then, a reasonable plan is two sessions a week with steadily increasing load, plus a third if you recover well. Our exercise for longevity guide shows how to structure them.

Sleep

When night sweats drive the problem, sleep habits alone only go so far, which is why the basics are about comfort. A cool bedroom and light bedding make night sweats easier to bear, though trials have not shown that cooling reduces hot flashes.[13] A fixed wake time, meanwhile, helps keep your sleep rhythm steady.

Insomnia that outlasts the night sweats, or comes without them, needs a different approach. CBT-I is a structured talking therapy for long-term sleep problems, and it is the treatment to ask about. In a US trial in peri- and postmenopausal women with hot flashes, a version delivered by telephone improved insomnia.[29] In Germany, CBT-I can be covered by statutory health insurance as outpatient psychotherapy, because non-organic sleep disorders are a listed indication. You need a diagnosis and a licensed therapist (as of October 2026).[36] Our sleep and longevity guide covers the rest of the sleep basics.

Diet and alcohol

Diet is where the evidence is thinner than wellness marketing suggests. In a large Spanish trial, older adults at high risk of heart disease either ate a Mediterranean diet with olive oil or nuts or got advice to eat low-fat. The Mediterranean groups had fewer heart attacks, strokes and cardiovascular deaths combined.[31] Specific "menopause diets" have no such evidence.

Protein matters mainly as backup for strength training, and about 1.2 to 1.6 g per kg of body weight per day is a sensible range. In a pooled analysis of strength-training trials in adults, eating more than about 1.6 g/kg/day brought no further muscle gain.[30] That is a general figure, not a target worked out for perimenopause.

Alcohol is the other dietary lever, and its main effect is on sleep. It helps you fall asleep but disrupts the second half of the night,[32] so a nightcap mostly borrows from the early-morning hours. Whether it sets off hot flashes is unclear, and one study even linked current drinking to fewer hot flashes.[19] The Menopause Society does not recommend avoiding triggers as a treatment,[13] so your own pattern is the better guide: if you notice one, act on it.

Stress

Stress is where claims run furthest ahead of the evidence. Mindfulness, yoga and regular aerobic exercise are reasonable ways to manage stress and wellbeing, but The Menopause Society does not recommend them as a treatment for hot flashes. For hot flashes, CBT and clinical hypnosis have the stronger evidence,[13] so they are the non-drug options worth asking about before you look at medication.

HRT in perimenopause: what do the 2026 guidelines say?

Hormone therapy has a favourable benefit-risk balance for women under 60 or within 10 years of menopause, according to The Menopause Society (formerly NAMS).[4] That applies to women with bothersome hot flashes and no contraindications, meaning no medical reason against it. The German S3 guideline says HRT should be used for symptoms before age 60.[10] NICE, the UK guideline body, recommends offering HRT for hot flashes and night sweats after a discussion of benefits and risks that fits your age and health.[11] None of the three treats hormone therapy as off limits, whether it goes by HRT, as in the UK, or MHT (menopausal hormone therapy), as in international usage.

The decision is still individual and belongs in a consultation with your Frauenärztin, Gynäkologin or, in Austria, a Wahlärztin. Your age at the start, the type of HRT and your own history all change the balance.

Why the old fear came from older women

Much of the old fear of HRT goes back to the Women's Health Initiative (WHI), a large US trial. Its original results came from women with an average age of 63,[2] so they cannot simply be applied to women in their late 40s and early 50s. The harms were real, though: combined HRT raised the risk of stroke, blood clots in the lungs and breast cancer while women were taking it.[27] Absolute risks were much lower in women aged 50 to 59,[27] and over 18 years of follow-up, death rates did not differ between hormone therapy and placebo.[2]

Age at the start also mattered in the ELITE trial. Estradiol slowed artery-wall thickening in women who started within six years of menopause, but not in women who started ten or more years after it. The trial did not test the years in between, found no effect on coronary CT scans, and measured an early marker rather than heart attacks or strokes.[3] All of these trials enrolled postmenopausal women, and none tested HRT started during perimenopause.

Breast cancer depends on the type of HRT

Breast cancer risk depends on the type of HRT and how long you take it. In long-term WHI follow-up, the rise in breast cancer was concentrated in women taking estrogen plus a progestin. Women on estrogen alone had fewer breast cancers and fewer breast cancer deaths.[9]

That reduction was seen with one estrogen (conjugated equine estrogen) in women who had had a hysterectomy. Women with a uterus, which means almost everyone in perimenopause, need a progestogen (a progesterone-like hormone) as well. With combined HRT, breast cancer risk rises the longer you take it, and some extra risk remains for at least 10 years after stopping.[11, 26] Large observational data also show a small rise with estrogen-only HRT, which NICE describes as very little or no increase.[11, 26] Vaginal estrogen was the exception, with no excess risk in these data.[26]

Tablet or patch, and who should not start

Beyond breast cancer, your heart and blood-vessel history, your migraine pattern, the type of progestogen and the route all shape which HRT suits you, if any. Estrogen tablets raise the risk of blood clots, and combined HRT with oral estrogen raises stroke risk. Estrogen through the skin (patch, gel or spray) does not raise clot risk and is unlikely to raise stroke risk. That makes it the usual choice if your clot risk is higher, for example with a BMI over 30.[10, 11]

For some women the question is whether to start at all. HRT may not be suitable, or needs specialist advice first, if you have had breast, ovarian or womb cancer, a blood clot, a heart attack or stroke, untreated high blood pressure or liver disease, or if you could be pregnant.[11, 39]

Bleeding after you start

Systemic HRT acts on the whole body, unlike vaginal estrogen. Once you start it, bleeding is common in the first 6 months and in the 3 months after a change of dose or product.[11] Unscheduled bleeding beyond those windows needs prompt checking.[11] On sequential (cyclical) combined HRT, a regular bleed at the end of each progestogen phase is expected and is not this kind of bleeding.[43]

Regulated hormones versus "bioidentical" mixes

Compounded "bioidentical" hormones, mixed individually outside the regulated product system, are no safer shortcut. NICE tells doctors to explain that the effectiveness and safety of unregulated hormone preparations are unknown.[11] If "bioidentical" matters to you, ask about the regulated estradiol patches and gels available on prescription.

What changed on US labels

Regulators have moved as well. In November 2025 the US FDA announced that it would remove the broad boxed warnings on cardiovascular disease, breast cancer and probable dementia from hormone therapy labels.[12] In February 2026 it approved the first six updated labels (as of October 2026).[40] The risks of heart disease and breast cancer stay in the labels' warnings section, so they have moved rather than disappeared.[41]

The one boxed warning the FDA kept is the endometrial (womb-lining) cancer warning for systemic estrogen alone.[12, 41] That is why anyone with a uterus who takes systemic estrogen needs a progestogen alongside it. The label change does not settle dementia either: NICE notes the risk might rise with combined HRT started at 65 or over.[11] European labels are set separately by the EMA and national agencies.

Which guidance applies?

Three references shape the advice in 2026:

  • NICE NG23 (UK; substantive update November 2024, last amended April 2026).[11]
  • The NAMS 2022 Hormone Therapy Position Statement[4] (NAMS is now called The Menopause Society)
  • The DGGG/OEGGG S3 guideline Peri- und Postmenopause (AWMF 015-062, the 2020 version with a September 2020 addendum)[10]

The German guideline comes with a caveat. Its validity in the AWMF register (Germany's official guideline database) ran out at the end of 2024, and a revision has been under way since 2025, as of October 2026[10] When a doctor in Germany, Austria or Switzerland quotes the S3, ask whether they mean the 2020 text or a newer version. For protocol-level detail on HRT in these three countries, see our HRT and TRT guide.

The options side by side

The main treatment options differ in what they help with and in what they rule out:

Option Mainly helps with Note
Systemic HRT/MHT Hot flashes, sleep, bone Benefit-risk favourable under 60 or within 10 years of menopause (NAMS).[4]; NICE: offer for hot flashes after an individual risk discussion[11]
Vaginal estrogen Dryness, recurrent UTIs, painful sex Works locally at a very low dose[11]
Fezolinetant (Veoza), elinzanetant (Lynkuet) Hot flashes, night sweats Prescription-only non-hormonal neurokinin blockers, EU-approved 2023 and 2025[22, 23] Not in pregnancy; use non-hormonal contraception if you could conceive. Fezolinetant: liver blood tests, and not with pills containing ethinylestradiol or with fluvoxamine.[22] Elinzanetant: can cause drowsiness; avoid grapefruit[23]
SSRIs/SNRIs, gabapentin Hot flashes Prescription options when hormones are not suitable[13]; NICE advises against routinely offering SSRIs or SNRIs as first-line treatment for hot flashes alone[11]
CBT, clinical hypnosis Hot flashes; CBT also helps sleep and mood Good trial evidence, no drugs involved[11, 13]
Strength training Bone, muscle Supervised heavy training raised spine density[7]

Sources: NAMS, NICE NG23 and the EMA product information for Veoza and Lynkuet, as of October 2026.

Whichever row looks closest, start that consultation with the symptom you most want help with and your own medical history.

How do you build a sensible check-up?

A sensible perimenopause check-up starts from a short baseline and adds tests only when there is a reason. That approach also fits the German system, where no Krankenkasse reimburses a perimenopause panel as a screening package. For most women entering or in perimenopause, the baseline is blood pressure, a lipid panel (blood fats), HbA1c (long-term blood sugar) and at least one validated mental-health questionnaire. Together they cover the main risks of this stage.[16, 28]

TSH (thyroid) and ferritin (iron stores) are worth adding when your history or symptoms give a reason, for example heavy periods or unexplained tiredness. Vitamin D testing makes sense only for a specific reason, such as osteoporosis or a condition that affects absorption. The Endocrine Society advises against routine testing in healthy adults.[34]

The questionnaire is the part that routinely gets left out, even though it takes five minutes. A short validated form such as the PHQ-9 for depression or the GAD-7 for anxiety makes sense at a stage when depression is more likely.[28] If it flags anything, outpatient psychotherapy is a GKV benefit in Germany once a licensed therapist has made a diagnosis.[36]

What insurance pays for

When there is a clinical reason, the gesetzliche Krankenkasse (GKV, statutory health insurance) generally covers the following (as of October 2026):

  • a gynaecological exam
  • basic blood work: TSH (thyroid), ferritin (iron stores), full blood count, lipids, and HbA1c (long-term blood sugar) when risk factors are present
  • a bone density scan (DEXA, Knochendichtemessung) when concrete findings point toward osteoporosis drug treatment, for example a fracture without adequate trauma, and when it is repeated to check a running treatment.[35]

Routine DEXA screening of women without such findings is not covered and lands in IGeL/Selbstzahler (self-pay) territory[35] If you have had a fracture without a proper accident, ask first about a GKV-covered scan.[35] An elective baseline scan, for example with a family history alone, is self-pay. The age-65 threshold you may have read about is not the German GKV rule. It comes from the US Preventive Services Task Force, which recommends screening for all women from 65 and for younger postmenopausal women at raised risk.[35, 42]

The same self-pay route applies to "menopause panels" with estradiol, FSH, LH, AMH and progesterone, and to cardiometabolic panels beyond standard lipids. Before you pay for a hormone panel, ask what question it is meant to answer and whether the day of your cycle matters for it. From 45, perimenopause is diagnosed without these tests, and below that age FSH has a defined role.[11]

In Austria, the Wahlärztin route (a private doctor without a public insurance contract) gives you longer appointments and easier access to extended panels. You pay the invoice first and then claim part of it back from your insurer, which the practice often submits for you. The ÖGK, Austria's main public health insurer, refunds 80 percent of what it would have paid a contract doctor, as of October 2026. That is usually well below 80 percent of the bill.[37]

Whichever system pays for the rest, one useful part of the check-up costs nothing: tracking your cycle in a notebook or an app. Since the diagnosis from 45 rests on your cycle pattern,[11] that record is the one worth bringing to your first appointment.

Frequently asked questions

Am I already in perimenopause?

If you are in your 40s and your cycle length starts to vary by 7 days or more, or you notice new sleep problems, mood changes or hot flashes, you may be in early perimenopause.[1] From 45, doctors diagnose it from these symptoms and cycle changes without a blood test.[11] Between 40 and 45, an FSH test can help if early menopause is suspected.[11] A conversation with your Frauenärztin is the right next step.

Can a blood test or home test confirm perimenopause?

Usually not, because home urine kits measure FSH, which swings in perimenopause, so one result proves little either way.[1] NICE tells doctors to diagnose perimenopause from symptoms and cycle changes alone from age 45, and not to use AMH, estradiol or similar tests for it.[11] An FSH blood test is only worth considering between 40 and 45, or under 40, and it is not reliable while you take the combined pill.[11] To sort your symptoms before an appointment, try our [menopause symptom checker](/en/menopause-test).

How long does perimenopause last?

Usually several years, and longer the earlier it starts.[24] In the SWAN study, the stretch up to the final period typically lasted about 4 years in women who started late and about 8 to 9 years in women who started young.[24] Perimenopause also takes in the 12 months after that final period, because only then is menopause confirmed.[1] Symptoms can outlast the transition: in SWAN, half of the women with frequent hot flashes still had them after 7.4 years, and the typical woman kept them for 4.5 years after her final period.[5]

Can perimenopause start in your 30s?

It can, but it is uncommon, since most women notice the first changes in their mid to late 40s.[14] If your periods stop or become rare before 40, doctors check for premature ovarian insufficiency (POI, the ovaries winding down early), and NICE asks for raised FSH on two blood tests 4 to 6 weeks apart.[11] The 2024 international POI guideline accepts a single raised FSH (above 25 IU/L) after at least four months of irregular or missing periods, and repeats the test when the picture is unclear.[33] Menopause between 40 and 44 counts as early menopause,[11] and either way a proper workup with your gynaecologist is worth it.

Why are my periods closer together or heavier in perimenopause?

In early perimenopause, cycles often get shorter first and then start to vary by a week or more, and later gaps of 60 days or more are typical.[1] Estradiol can run high in some cycles as hormone levels swing,[1] which can build up a thicker lining and make bleeding heavier. Get checked if you bleed between periods or after sex, if bleeding lasts much longer than usual or is heavy enough to disrupt your day or leave you exhausted, or if any bleeding returns after 12 months without a period.

Can I still get pregnant in perimenopause, and what if I am on the pill?

Yes, because you still ovulate, just irregularly, which is why NICE advises talking about contraception with women who have menopausal symptoms.[11] The combined pill hides your natural cycle, so the cycle changes that point to perimenopause are invisible and FSH tests are unreliable while you take it, but hot flashes, sleep changes or mood shifts on the pill are still worth raising.[11] HRT does not prevent pregnancy, and the usual advice is to keep using contraception until 2 years after your last period if you are under 50, or 1 year after it if you are 50 or over.[39] If a non-hormonal hot-flash drug such as fezolinetant is an option, the method matters, because it does not mix with ethinylestradiol pills.[22]

Is HRT/MHT safe in 2026?

For women under 60 or within 10 years of menopause who have bothersome symptoms and no contraindications, The Menopause Society rates the benefit-risk balance of hormone therapy as favourable,[4] the German S3 guideline supports HRT for symptoms before 60,[10] and NICE recommends offering it after an individual risk discussion.[11] Long-term WHI follow-up found no difference in death rates,[2] in WHI absolute risks were lower in women aged 50 to 59 than in older women,[27] and in November 2025 the US FDA announced it would remove the broad boxed warnings from labels.[12] Estrogen through the skin avoids the clot risk of tablets, while past breast cancer, a blood clot, a heart attack or stroke call for specialist advice first.[11, 39] The details are in our [HRT/TRT guide](/en/guide/hormonersatztherapie-hrt-trt), and the decision belongs with your Frauenärztin or Gynäkologin.

Who should not take HRT?

HRT may not be suitable, or needs specialist advice first, if you have had breast, ovarian or womb cancer, a blood clot, a heart attack or stroke, untreated high blood pressure or liver disease, or if you could be pregnant.[11, 39] If your clot risk is raised, for example with a BMI over 30, estrogen through the skin (patch, gel or spray) is the usual choice, because unlike tablets it does not raise clot risk.[10, 11] For women who cannot or do not want to take hormones, non-hormonal drugs and CBT can ease hot flashes.[13, 22]

Should I see a doctor or wait it out?

See a doctor if symptoms interfere with sleep, work, mood or relationships, because those are the thresholds that matter, not severity on paper. Persistent low mood, new anxiety or intrusive thoughts deserve specific attention, because the risk of depression is higher in this window.[28] If you have thoughts of self-harm or suicide, contact Telefonseelsorge Deutschland (0800 111 0 111 or 0800 111 0 222, free, 24/7), Telefonseelsorge Österreich (142) or Die Dargebotene Hand Schweiz (143); if you are in immediate danger or cannot keep yourself safe, call 112 (Germany, Austria, Switzerland) or go to the nearest emergency department, and do not stay alone. Waiting it out is reasonable only if symptoms are mild and you prefer not to intervene.

Are bioidentical hormones safer than regulated HRT?

No. Regulated estradiol products, including patches and gels absorbed through the skin, are available on prescription. The problem is unregulated compounded preparations sold under the "bioidentical" label: NICE tells doctors to explain that the effectiveness and safety of unregulated hormone preparations are unknown.[11] If "bioidentical" matters to you, ask your Frauenärztin or Gynäkologin about regulated products rather than sourcing something outside the regulated system.

What helps with menopausal sleep disturbance?

If night sweats wake you, treating them directly works best: options include HRT, CBT or clinical hypnosis, and non-hormonal prescription drugs such as SSRIs, SNRIs, gabapentin and the neurokinin blockers fezolinetant (Veoza, EU-approved 2023) and elinzanetant (Lynkuet, EU-approved November 2025).[13, 22, 23] For insomnia that night sweats do not fully explain, CBT-I is the treatment to ask about, and German statutory insurance can cover it as psychotherapy.[29, 36] A cool bedroom is a sensible comfort measure, though trials have not shown it reduces hot flashes.[13]

Are fezolinetant and elinzanetant safe?

Both are approved prescription drugs for hot flashes, but each comes with firm safety rules that your doctor should check before and during treatment.[22, 23] Fezolinetant needs liver blood tests before you start and monthly for the first three months because of rare liver injury, and you should stop it and call your doctor at once if you notice itching, yellow skin or eyes, dark urine or pain in the upper abdomen.[22] It must not be combined with moderate or strong CYP1A2 blockers, which include combined pills containing ethinylestradiol and the antidepressant fluvoxamine, and it is not recommended during treatment for breast cancer or other estrogen-dependent cancers.[22] Elinzanetant can make you drowsy, should not be taken with grapefruit, and strong CYP3A4 blockers such as some antifungals and antibiotics are not recommended with it.[23] Neither drug is recommended together with estrogen HRT (vaginal estrogen is fine), and both are off limits in pregnancy, so use a non-hormonal method if you could still conceive.[22, 23] In the UK, NICE now recommends fezolinetant when HRT is unsuitable.[11]

Do supplements or herbal remedies help with perimenopause?

The evidence is weak: a Cochrane review found too little good evidence that black cohosh eases hot flashes,[21] and The Menopause Society does not recommend herbal remedies or dietary supplements for hot flashes, soy products included.[13] Black cohosh (Traubensilberkerze) has also been linked to rare liver damage, so stop and see a doctor at once if you notice tiredness, loss of appetite, yellow skin or eyes, dark urine or severe upper-abdominal pain.[38] St John's wort can interact seriously with medicines such as tamoxifen, blood thinners and epilepsy drugs.[11] Tell your doctor before you take any of them.

What about weight gain during perimenopause?

Weight gain in midlife, about half a kilo a year on average, is mostly an effect of age rather than menopause,[20] but fat shifts toward the belly across the transition.[20] Strength training plus enough protein (about 1.2 to 1.6 g per kg of body weight per day) helps you build muscle while your body composition shifts.[30]
