Menopause: symptoms, FSH levels, and the blood tests that matter after your last period

Menopause is the final menstrual period, a single date recognised only once 12 months have passed with no period. In the US it arrives at an average age of 52, and every year after it is postmenopause. ² The symptoms people search for, hot flashes, night sweats, poor sleep and mood change, usually start in perimenopause, the transition before it, and often run for years after. ² In otherwise healthy people aged 45 or over, menopause is identified without blood tests. ¹ After the last period the useful blood work changes: FSH (follicle-stimulating hormone, the brain's signal to the ovaries) stays high and adds little, while LDL cholesterol and ApoB, the particles that carry cholesterol into artery walls, jump around the final period. ⁸ What to do next: at your next visit, ask your clinician to review your lipid panel, blood sugar and bone health against your age and risk, and report any bleeding after menopause promptly.

What is menopause?

Menopause is the point when periods stop for good because the ovaries no longer release eggs or make much estrogen and progesterone. The National Institute on Aging calls it a normal part of aging, not a disease, and notes that you only know you have reached it once you have gone a full year with no period or spotting. ² Removing both ovaries brings menopause on at once: someone who has that surgery and does not take hormones stops having periods and can have menopause symptoms immediately. ²

Three words get mixed up. Perimenopause is the transition before the final period plus the 12 months after it. Menopause is the final period itself. Postmenopause is everything after. ³ STRAW+10 (the Stages of Reproductive Aging Workshop, the research staging system) splits postmenopause further: FSH keeps climbing and estradiol keeps falling for about 2 years after the final period, then both stabilise, and the whole early postmenopause lasts roughly 5 to 8 years. ³ The perimenopause guide covers the transition in detail, including why blood tests are unreliable during it.

Premenopausal vs perimenopausal vs postmenopausal

Early menopause and premature ovarian insufficiency

Menopause before 45 is called early, and loss of normal ovarian function before 40 is premature ovarian insufficiency (POI). These do need blood tests. NICE diagnoses POI under 40 from menopause-type symptoms, including no or infrequent periods, plus a raised FSH on 2 blood samples taken 4 to 6 weeks apart, and says not to diagnose it from a single test. ¹ Between 40 and 45 it suggests considering FSH to confirm menopause. ¹ NICE also notes that people from some ethnic minority backgrounds and people with some lifelong conditions may reach menopause younger. ¹ An early menopause leaves more years with low estrogen, which matters for bone and heart, so it is managed by a clinician rather than waited out.

Is there a blood test for menopause?

For most people over 45, no test is needed. NICE says to identify menopause, without laboratory tests, in otherwise healthy people aged 45 or over who have not had a period for at least 12 months and are not using hormonal contraception. ¹ It lists tests not to use for this at 45 or over, including anti-Müllerian hormone, inhibin and estradiol, and says not to use FSH in anyone on combined hormonal contraception or high-dose progestogen, because those medicines hold FSH down. ¹ After a hysterectomy, when there are no periods to count, menopause is identified from the type and combination of symptoms. ¹

FSH 15, 30, 40, 60, 90 or over 100: what the number means for menopause

FSH is reported in mIU/mL or IU/L, which give the same number. These readings use Labcorp's adult female ranges; your lab's range comes first. ⁴ STRAW+10 treats a random FSH above 25 IU/L as typical of the late transition, the 1 to 3 years before the final period. ³

• FSH of 15 or 20: above the follicular range (top 12.5) and below the postmenopausal one (from 25.8). Common in perimenopause; it does not rule menopause in or out. ⁴
• FSH of 30 or 35: just inside the postmenopausal range. Fits late perimenopause or menopause; the period history decides which. ³⁴
• FSH of 40 or 50: inside the postmenopausal range. Without 12 months of no periods, a single value like this can still fall back in perimenopause. ³
• FSH of 60, 70 or 80: inside the postmenopausal range and typical in the years after the final period. ⁴
• FSH of 90 to 134: still inside Labcorp's postmenopausal range. A higher number does not mean worse symptoms, weaker bones or higher heart risk. ⁴
• FSH above about 135: above Labcorp's postmenopausal range, which is unusual; the ordering clinician reads it with estradiol, other pituitary hormones and the full picture. ⁴

Blood tests that matter after menopause

The hormone numbers settle, but heart and metabolic numbers keep moving. The SWAN study (the US Study of Women's Health Across the Nation) followed 1,054 women for 10 years and compared each heart risk factor before and after the final period. Most changed steadily with age. Total cholesterol, LDL cholesterol and ApoB were different: they rose sharply within the year before and after the final period, a jump tied to menopause itself rather than to birthdays. ⁸

That is why postmenopausal blood work is a heart and bone check. The table lists the markers a clinician usually weighs after menopause, each linked to its own page with full ranges. The high cholesterol guide covers what to do about raised lipids, and how to read your lipid panel explains each line of the report.

How the results read together

If you are holding a lipid panel, the tool below reads it line by line. The LDL calculator estimates LDL from total cholesterol, HDL and triglycerides, and the cholesterol ratio calculator gives the total-to-HDL ratio.

Bone: when density is checked after menopause

Bone loss has no symptoms until a fracture, and no routine blood test measures bone density. The test is a DEXA scan (dual-energy X-ray absorptiometry, a low-dose X-ray of the hip and spine). The US Preventive Services Task Force (USPSTF) recommends screening all women aged 65 or older, and postmenopausal women under 65 who are at increased risk on a clinical risk tool; menopausal status, low body weight, a parent with a hip fracture, smoking and heavy drinking are among the risk factors it names. ¹⁰ Osteoporosis affects 27.1% of US women aged 65 or older. ¹⁰ Blood tests explain why bone is thin rather than how thin; see bone tests explained and the osteoporosis guide. A low vitamin D has its own guide: vitamin D deficiency.

Conditions that can look like menopause

Postmenopausal bleeding: why it is always checked

Most bleeding after menopause comes from harmless causes such as thin, dry vaginal tissue or a polyp, but it is also the warning sign of endometrial cancer. A 2018 meta-analysis of 129 studies and more than 40,000 women in JAMA Internal Medicine found that 91% of women with endometrial cancer had postmenopausal bleeding, and that 9% of women with postmenopausal bleeding had endometrial cancer. ¹¹ The usual first steps are an exam and a transvaginal ultrasound or a sample of the womb lining, chosen by the clinician.

Menopause treatment: what can help, and how strong the evidence is

Treatment has two jobs after menopause: easing symptoms, and lowering long-term heart and bone risk. Lifestyle and guideline care come first; prescription options are listed as facts, and whether any fits is decided with a clinician who knows your history.

Hormone therapy and the timing question

Hormone therapy, also called hormone replacement therapy (HRT), replaces estrogen; anyone with a uterus also takes a progestogen (a progesterone-like hormone) to protect the womb lining. The Menopause Society's 2022 position statement says the risks differ with the type, dose, duration, route (pill, patch, gel or vaginal), timing of the start and whether a progestogen is used. ⁶ Its central finding is about timing:

For women aged younger than 60 years or who are within 10 years of menopause onset and have no contraindications, the benefit-risk ratio is favorable for treatment of bothersome VMS and prevention of bone loss.The 2022 hormone therapy position statement of The North American Menopause Society (VMS: vasomotor symptoms, meaning hot flashes and night sweats)

Started after 60 or more than 10 years from menopause, the same statement judges the balance less favorable, because the absolute risks of coronary heart disease, stroke, blood clots and dementia are higher. ⁶ US labels are changing. On 10 November 2025 the FDA asked the makers of menopausal hormone therapy to remove the statements about heart disease, breast cancer and probable dementia from the boxed warning, the label's most prominent warning. ⁹ The heart disease and breast cancer warnings stay elsewhere in the label, the boxed warning about endometrial (womb lining) cancer stays on systemic estrogen-alone products, labels for systemic products add that starting treatment for moderate to severe hot flashes can be considered before 60 or within 10 years of menopause, and vaginal estrogen labels are condensed to the safety information that fits a local product. ⁹ Updated labels for the first products followed from February 2026. ⁹ A label change does not change an individual's risks, so the decision still rests on personal history such as breast cancer, clots, stroke or liver disease.

Vaginal and urinary symptoms

The genitourinary syndrome of menopause is the medical name for vaginal dryness, pain during sex, urgency and repeat urinary infections caused by low estrogen. Unlike hot flashes, it tends to build with time rather than fade. STRAW+10 notes these symptoms become increasingly common in late postmenopause. ³ NICE recommends offering vaginal estrogen, alone or with non-hormonal moisturisers and lubricants, and explains that serious adverse effects are very rare because little is absorbed. ¹ The Menopause Society lists low-dose vaginal estrogen, vaginal DHEA (prasterone) and oral ospemifene as options when over-the-counter products are not enough. ⁶

Non-hormonal options for hot flashes

The Menopause Society's 2023 nonhormone statement recommends cognitive behavioral therapy, clinical hypnosis, SSRIs or SNRIs (antidepressant families that also calm hot flashes), gabapentin and fezolinetant, a non-hormonal pill that blocks a brain receptor involved in temperature control, all at its strongest level of evidence; oxybutynin and weight loss are also recommended at lower levels. ⁵ It does not recommend supplements, herbal remedies, soy, cooling techniques or avoiding triggers as treatments, and it concludes that hormone therapy remains the most effective option. ⁵

Supplements after menopause: what the evidence shows

No supplement has good evidence for hot flashes. ⁵ For bone, enough vitamin D and calcium from food, sunlight or supplements is part of standard care; the vitamin D guide covers forms and amounts, and the Endocrine Society's 2024 guideline suggests against routine vitamin D testing in the general population. ⁷ The omega-3 guide covers what fish oil does for triglycerides, and the magnesium guide covers forms and the kidney caution.

If you and your clinician decide vitamin D makes sense, D Complex is one of the products LifeFrom can put in your daily pouch, and the shop's ready-made packs include a Women's wellness pack and a Bones pack. The Bones pack also contains calcium, and vitamin D with calcium can push blood calcium too high in people with kidney disease, kidney stones or a parathyroid problem, so they need a clinician's view first.

Monitoring and retesting after menopause

Questions to ask your clinician

• Given my age and history, do I need any hormone test, or is my period history enough?
• Has my LDL or ApoB changed since before my periods stopped, and what is my 10-year heart risk?
• Has my lipoprotein(a) ever been measured?
• Is my HbA1c or fasting glucose in the prediabetes range?
• When should I have a bone density scan, given my risk factors?
• Am I a candidate for hormone therapy, and which type and route fit my history?
• What non-hormonal options fit if hormones are not right for me?
• Do I need vitamin D or calcium, and should my calcium level be checked first?
