10 Myths About Menopause — What the Science Really Says

By Prof. Nelly Pitteloud

Menopause is a universal physiological transition, yet it remains one of the most misunderstood aspects of women’s health. Here we separate science from myth — and highlight the profound links between estrogen decline, metabolic health, and long-term disease risk.

Myth 1: Menopause is just hot flashes

Scientific reality: While vasomotor symptoms (hot flashes and night sweats) affect ~80% of menopausal women (Freeman et al., 2005), estrogen’s systemic role means the impact goes far beyond thermoregulation.

Estrogen receptors (ERα and ERβ) are expressed in the brain, vasculature, muscle, bone, adipose tissue, and the immune system (Miller et al., 2019). The hypoestrogenic state of menopause is associated with:

• Neurocognitive changes: reduced verbal memory, slower processing speed (Greendale et al., 2009)

• Mood disturbances: linked to altered serotonergic activity and HPA axis dysregulation

• Musculoskeletal pain: estrogen modulates nociception and joint inflammation

• Metabolic shifts: increased central adiposity and insulin resistance (Carr, 2003)

• Miller VM et al. (2019). Biol Sex Differ, 10(1): 17.

Myth 2: Everything is a menopause symptom

Scientific reality: While perimenopause can explain multiple nonspecific symptoms (fatigue, weight gain, insomnia), it should not become a diagnostic catch-all.

For example:

• Fatigue may stem from iron deficiency, subclinical hypothyroidism, or B12 deficiency.

• Joint pain may reflect estrogen withdrawal, but could also indicate early osteoarthritis or autoimmune rheumatologic disease.

• Weight gain may be age-related, not hormonally driven (Lovejoy et al., 2008).

Clinicians must conduct a differential diagnosis and not automatically attribute symptoms to hormones.

Myth 3: Hormone therapy (HT) is dangerous

Scientific reality: The 2002 WHI study initially reported increased risks with estrogen-progestin therapy, but subgroup analyses revealed age and timing are critical.

In women aged 50–59, HT does not increase all-cause mortality, and reduces coronary artery disease risk when started within 10 years of menopause (Manson et al., 2013). HT also reduces:

• Osteoporotic fracture risk by 30–40%

• Type 2 diabetes incidence by 20–30% (Salpeter et al., 2006)

• Colon cancer risk

Risks:

• Slightly increased venous thromboembolism (VTE) risk with oral estrogen

• Breast cancer risk mainly with long-term use of estrogen + progestin

Transdermal estrogen and micronized progesterone have more favorable profiles.

• Salpeter SR et al. (2006). J Gen Intern Med, 21(4): 363–366.

Myth 4: Hormones are the only option

Scientific reality: For women who cannot or do not want hormone therapy, evidence-based nonhormonal options include:

• Paroxetine: an SSRI with FDA approval for vasomotor symptoms

• Gabapentin and pregabalin: modulate hypothalamic thermoregulatory circuits

• Fezolinetant: a neurokinin 3 receptor antagonist targeting KNDy neurons (2023 FDA-approved)

• CBT and paced breathing: proven benefits in vasomotor and sleep symptoms (Hunter et al., 2019)

• Improving life style: physical activities like yoga, healthy diet, enough sleep, decreasing stress

Individualized care plans should consider symptom burden, cardiovascular and cancer risk, and personal preference.

Myth 5: Natural supplements are safer

Scientific reality: Many “natural” supplements (black cohosh, red clover, phytoestrogens) lack standardized clinical data. Bioidentical hormones from compounding pharmacies are not FDA-regulated, which raises concerns about purity, potency, and safety (Pinkerton & Santoro, 2020).

FDA-approved “bioidentical” HT is available (e.g., estradiol, micronized progesterone), offering evidence-based alternatives in precise dosages.

"Natural" does not mean safe — especially without clinical trial validation.

Myth 6: You just need to tough it out

Scientific reality: Untreated vasomotor symptoms (VMS) are linked to worse cardiovascular and cognitive outcomes. The SWAN study showed:

• Frequent VMS → increased carotid intima-media thickness

• Sleep disruption → elevated cortisol and glucose, impaired insulin sensitivity

• Vaginal dryness → higher rates of UTI and dyspareunia

  
  

Estrogen also influences:

• Bone remodeling via osteoblast activation

• Muscle mass maintenance

• Adipose tissue distribution

Myth 7: Symptoms are short-lived

Scientific reality: Median duration of hot flashes is 7.4 years, with some women experiencing symptoms into their 70s. Duration correlates with ethnicity, BMI, smoking status, and age at onset.

Brain, urogenital, and metabolic changes persist long after menstruation ends.

• Avis NE et al. (2015). JAMA Intern Med, 175(4): 531–539.

Myth 8: Sex life ends after menopause

Scientific reality: While low estrogen can cause dyspareunia and reduced lubrication, these effects are treatable. Vaginal estrogen and moisturizers significantly improve symptoms.

Testosterone therapy — although off-label in the U.S. — has been shown to increase sexual desire in postmenopausal women (Witherby et al., 2021).

Sexual health in menopause is both hormonal and relational — and treatable.

Myth 9: You can’t get pregnant in perimenopause

Scientific reality: Ovulation may be sporadic, but fertility is not zero. Studies confirm that women over 40 — especially those with irregular but present cycles — are still capable of conceiving.

Risk of unplanned pregnancy persists until 12 consecutive months of amenorrhea and elevated FSH.

Myth 10: Menopause is always awful

Scientific reality: While symptoms are real, menopause also marks a transition to neurological, metabolic, and psychological recalibration. Some women report increased life satisfaction, confidence, and mental clarity post-menopause (Avis et al., 2009).

This phase can be a metabolic reset — a chance to address bone density, body composition, and heart health.

Conclusion: A Metabolic Lens on Menopause

Menopause is not a disease — but it is a biological inflection point. Understanding the neuroendocrine, metabolic, and immune changes of this phase allows for:

• Personalized interventions

• Cardiometabolic disease prevention

• Optimized brain and bone health
