Menopause Part 1: Education, Physiology, and Preventive Screening

by Dr. Bojana Jankovic Weatherly, Melissa Reade MS, CDN, CNS, NB-HWC | April 27, 2026 | Articles, Hormone Health

Menopause is a natural biological process marking the end of a woman’s reproductive years, beginning on average at 51. 4 years of age in the U.S.¹. Although menopause itself is not a disease, the hormonal fluctuations it brings can profoundly impact multiple body systems, increasing the risk of cardiovascular disease, osteoporosis, metabolic disorders, cognitive decline, and mood imbalances.²

To navigate this stage with grace and resilience, an integrative, evidence-based approach including medical interventions, nutritional strategies, lifestyle modifications for sleep, stress management, and exercise, as well as select holistic therapies, can help mitigate symptoms, support overall well-being, and promote a longer health span for women. ³

This article provides an overview of changes associated with menopause and preventive screening strategies that should be implemented to lower the risk of disease and improve quality of life. To learn more about menopausal hormone therapy and non-hormonal therapies, read this article.

Menopause as a Window of Opportunity for Whole-Body Health

Menopause is diagnosed after 12 consecutive months without a menstrual period, reflecting a permanent decline in ovarian follicular function and stabilization of estrogen at a significantly lower level. This hormonal transition marks more than the end of reproductive capacity-it signals a shift in physiology that has profound, lifelong health implications.⁴

Estrogen plays a protective role across multiple organ systems, and its decline during the menopausal transition affects cardiovascular, skeletal, metabolic, genitourinary, and cognitive health. For the last two decades, since the WHI study came out, women were expected to simply endure these changes with minimal hormonal support. Today, however, evidence-based practice recognizes menopausal transition as a critical window of opportunity–a time to both relieve current symptoms and implement strategies that can protect long-term health. Women will spend nearly 40% of their lives in menopause, underscoring the importance of proactive care .⁵⁶

Overview of Common Symptoms

Many women experience one or more of the following during the menopausal transition:

Vasomotor symptoms (VMS): hot flashes and night sweats.
“Brain fog”/cognitive complaints such as memory lapses, trouble concentrating, and word-finding difficulty
Significant reduction in bone density
Reduction in muscle mass
Mood changes: increased anxiety, depressed mood, and irritability
Poor sleep
Genitourinary symptoms (GSM): vaginal dryness, pain with sex (dyspareunia), urinary frequency/urgency
Decreased libido
Headaches
Joint and muscle aches/myalgias
Weight distribution changes, central adiposity (increased abdominal fat)
Skin changes (thinning, reduced elasticity)
Hair loss
Worsening of biomarkers, such as increase in lipid markers LDL-C and ApoB, and increase in blood glucose

Clinically, menopause should be seen as both a time to alleviate symptoms and improve quality of life, and a window to engage in age-appropriate risk factor assessment (or, hopefully, continue engaging in it). It is then the role of your healthcare team to discuss how best to establish (or reassess) foundational health habits that reduce the risk of, or delay, cardiovascular disease, fracture, metabolic dysfunction, cancer and cognitive decline.⁷In addition to lifestyle and nutritional interventions, medications, supplements and other integrative modalities, while outside the scope of this article, may be used when indicated.

Systemic Health Impacts of Menopause

Cardiovascular Health
Menopause is one of the most significant risk factors for heart disease in women. Estrogen plays a protective role in vascular function, supporting healthy endothelial function, arterial flexibility, and cholesterol regulation. As estrogen levels decline, women experience increased risk of hypertension, dyslipidemia, central adiposity, and cardiovascular disease, with particularly heightened risk in those who undergo early menopause. Cardiovascular disease develops gradually over years, influenced by genetics, lifestyle, inflammation, and other comorbidities, yet the hormonal shifts of menopause accelerate this process.⁸⁹

During and after the menopausal transition, women typically experience adverse changes in lipid profiles, including higher total cholesterol and LDL (“bad” cholesterol), lower HDL (“good” cholesterol), and often increased triglycerides, all of which contribute to a more atherogenic pattern. In addition, changes in lipoprotein particle characteristics, such as a rise in small dense LDL particles and shifts in apolipoproteins like ApoB, can further elevate cardiovascular risk beyond what traditional cholesterol numbers show, making a comprehensive lipid panel and interpretation with your clinician particularly valuable.

Importantly, menopause is often associated not only with changes in lipidprofile, but also with adverse changes in inflammatory markers and lower insulin sensitivity, which together provide a more complete picture of cardiovascular risk than total cholesterol alone. Understanding these patterns allows clinicians to move beyond a “one-number” approach and instead develop a personalized cardiovascular prevention plan–targeting diet quality, fiber intake, physical activity, metabolic health, stress, sleep, and when appropriate, medication–to meaningfully improve lipid profiles and long-term heart health.¹⁰ ¹¹

From an integrative perspective, prevention should be the focus, emphasizing the establishment of heart-healthy habits such as balanced nutrition, regular physical activity, stress management, and sleep hygiene, well before any clinical signs of heart disease emerge. ¹⁰ ¹¹ ¹² ¹³ ¹⁴

Metabolic Health

The decline in estrogen also promotes unfavorable metabolic changes, including increased visceral fat accumulation, (a shift toward an apple-shape appearance), reduction in muscle mass, insulin resistance, and a higher risk of type 2 diabetes. These changes contribute to the prevalence of overweight and obesity, metabolic syndrome, and inflammation-related diseases in postmenopausal women. Maintaining muscle mass through resistance training, ensuring adequate fiber and protein intake, and supporting metabolic health through nutrient-dense, anti-inflammatory foods are essential strategies to mitigate these risks.¹³

Bone and Musculoskeletal Health

Estrogen is critical for bone remodeling, suppressing bone resorption and maintaining bone density. Its loss during menopause accelerates bone loss, increasing the risk of osteopenia, osteoporosis, and fractures. Concurrently, age and hormone-related declines in muscle mass, known as sarcopenia, contribute to frailty, decreased metabolic rate, and impaired glucose control. These changes underscore the importance of interventions such as weight-bearing exercise, resistance training, and targeted nutrition, including sufficient protein, calcium, and vitamin D, to preserve musculoskeletal health and functional independence. ¹⁴ ¹⁵ ¹⁶

The reality of bone health statistics highlights why proactive assessment matters. Among U.S. women 65 years or older, data show that by the time women reach the age at which routine bone density screening is recommended, a significant proportion already have clinically meaningful bone loss. Approximately 27% of American women aged 65 and older have osteoporosis, and when both osteopenia (low bone mass) and osteoporosis are considered together, nearly 50% of women in this age group are affected by reduced bone density. This high prevalence is largely driven by postmenopausal estrogen loss and underscores why osteoporosis is often described as a “silent disease,” progressing for years before fractures occur.

Despite the substantial burden of disease, osteoporosis remains underdiagnosed and undertreated. Studies indicate that only 12% to 27% of women over age 65 who experience hip fractures receive appropriate bone density screening, highlighting a major gap in preventive care. Osteoporotic fractures, particularly hip fractures, are associated with significant morbidity, loss of independence, and increased mortality. Concurrent age- and hormone-related declines in muscle mass, known as sarcopenia, further compound fracture risk by contributing to frailty, balance impairment, and reduced metabolic resilience.

Current guidelines recommend routine bone density screening (DEXA) for women beginning at age 65, with earlier screening in younger postmenopausal women who have additional risk factors. In our practice, however, we encourage women to consider earlier evaluation of bone density, particularly in the early postmenopausal years, so that subtle declines in bone mass, whether osteopenia or early osteoporosis, can be detected well before a fracture occurs and appropriate preventive strategies can begin. Earlier DEXA assessment allows us to tailor nutrition, lifestyle, and medical interventions to optimize long-term skeletal health, rather than waiting until age 65 when a large proportion of women already have significant bone loss. ¹⁷¹⁸¹⁹

Cognitive Function and Mood

Estrogen also plays a key role in regulating neurotransmitters that support memory, mood, and executive function. As estrogen levels decline, many women report cognitive changes, often described as “brain fog”, along with shifts in mood, increased anxiety, or symptoms of depression during this stage of life. Sleep disruption is common and may be driven or worsened by vasomotor symptoms such as hot flashes and night sweats, which can fragment sleep and further impair cognitive and emotional regulation. When vasomotor symptoms are contributing to poor sleep quality, they should be specifically identified and addressed as part of a comprehensive treatment plan. Addressing sleep quality, vasomotor symptoms, stress management, physical activity, and nutrition during midlife is a key component of long-term brain health and emotional well-being. .¹⁷¹⁸

Genitourinary and Sexual Health

Genitourinary syndrome of menopause (GSM) is a common but often under-recognized consequence of estrogen loss. Thinning of vaginal and urinary tract tissues can lead to vaginal dryness, painful intercourse, recurrent urinary tract infections, and decreased sexual function, all of which can significantly affect quality of life. Early recognition and management of GSM symptoms can prevent progression and maintain sexual and urinary health. ¹⁹ ²⁰

Given the broad systemic effects of menopause on nearly every organ system, from the cardiovascular and metabolic to the musculoskeletal, cognitive, and genitourinary, midlife becomes a pivotal time for proactive screening and prevention. Early identification of emerging risk factors allows for timely interventions that can significantly reduce long-term disease burden and support healthy aging.

Prevention and Screening in Menopause and Midlife

Cardiometabolic Health

Measure blood pressure, fasting glucose, fasting insulin, HbA1c (provides a 3 month average of blood glucose), fasting lipid profile, ApoB, high sensitivity CRP, and Lp(a) as part of baseline midlife screening. For more information on lipid panel and related markers, the information it provides and what it means, read this article and this article.

Discuss risk assessment calculators and cardiac imaging with your physician to estimate your 10 and 30 year cardiovascular risk, and whether you have plaque in the arteries of your heart and need more aggressive treatment.

Monitor waist circumference and BMI, recognizing that central adiposity is a stronger predictor of risk than weight alone. ²¹
Screen for metabolic syndrome, as postmenopausal women often develop higher insulin resistance and visceral fat accumulation. ²²

Bone Health

Women ≥65 years should undergo DEXA screening for osteoporosis. Younger postmenopausal women with risk factors (early menopause, low body weight, smoking, family history of fracture) should also be screened. In our practice, we offer this screening at menopausal transition given the many women affected by osteopenia and osteoporosis.
Use FRAX scoring to help estimate fracture risk. ²³

Cancer Screening

Breast Cancer Screening

Guidelines recommend mammography for breast cancer screening, though recommended screening intervals vary somewhat among medical organizations. The National Comprehensive Cancer Network (NCCN) recommends annual mammography beginning at age 40. The U.S. Preventive Services Task Force (USPSTF) recommends biennial (every two-year) screening for women aged 40 to 74, citing a balance between early detection and minimizing potential harms such as false positives. The American Cancer Society (ACS) recommends annual screening from ages 45 to 54, with the option to continue annual screening or transition to biennial screening beginning at age 55.

In clinical practice, mammography is doneevery one to two years between the ages of 40 and 74 for average-risk women, with the specific interval individualized based on risk, personal values prior imaging findings, and discussion with a healthcare provider. Women with higher-than-average risk—such as those with a strong family history, known genetic mutations, or prior chest radiation—require a different screening approach and should follow personalized recommendations from their care team. ²⁴ ²⁵ In our practice, we encourage patients to calculate their breast cancer risk using the Tyrer-Cuzick calculator. High risk women should ideally be followed at a high risk program and be offered mammography and breast MRIs annually, rotating between mammogram and breast MRI every 6 months.

Cervical Cancer Screening

Cervical cancer screening guidelines recommend screening
- 21-29yo: every 3 years with Pap alone (21–29),
- 30-65yo: every 5 years with Pap+ high risk HPV testing, high risk HPV alone or every 3 years Pap alone
- Ages 65+: screening can stop if prior screenings were negative; shared decision making is recommended ²⁵

Colon Cancer Screening

Colon cancer screening should begin at age 45 and continue through age 75. ²⁶ High risk individuals (e.g., those with a family history, known genetic mutations, inflammatory bowel disease) start screening earlier and get screened more frequently than average risk individuals.

Mental Health and Cognition

Screen for depression and anxiety with validated tools (e.g., PHQ-9 and GAD-7. Your physician should be assessing this annually, or more frequently if there are any concerns with respect to mood symptoms or anxiety.

Assess for insomnia and screen for sleep disorders, if indicated.
Evaluate for cognitive concerns, especially in women with cardiovascular risk factors, as these correlate with higher risk of dementia.

Other Preventive Health

Assess thyroid function annually and if symptoms such as fatigue, cold intolerance, or weight changes arise. Hypothyroidism is more common in women and one quarter of women over 60 years old have thyroid autoimmunity.

Preventive blood work including nutrient panel, complete blood count, metabolic panel and other markers, customized to each individual.

Ensure vaccines are up to date. As we get older, our immunity weakens and we aren’t able to clear viruses and bacteria as efficiently. As a result, we are more prone to greater severity of symptoms and complications of infections. .

As screening helps identify emerging health risks, targeted nutrition, lifestyle and medical interventions form the foundation for managing these changes. In thesecond part of our series, we discuss nutrition and lifestyle recommendations that women should consider as part of their approach to optimize their health and function in midlife and beyond.
