Menopause and your heart: What the science says and what you can do

Menopause is a natural part of life but it is also a turning point for heart health. Research shows that the hormonal changes of the menopausal transition are associated with an increased risk of cardiovascular disease (CVD), which remains the leading cause of death in women worldwide.^1,2 The good news is that understanding these changes early can help you and your healthcare provider take steps to protect your heart during midlife and beyond.

Why is menopause considered a turning point for heart health?

Menopause marks a significant shift in cardiovascular risk for women. Before menopause, the incidence of heart disease in women is delayed by 10 years as compared to men,^1,2 a difference that is thought to be linked to the protective effects of estrogen on blood vessels during the reproductive years.

Studies show that the rate of cardiovascular disease in women at midlife between the ages of 40 and 65 is rising, and this increase coincides with the timing of the menopausal transition.¹ Women who experience menopause before age 45 may face a higher cardiovascular risk than those who go through menopause at the typical age of around 50.^2,5

This does not mean heart disease is inevitable. But it does mean the menopausal transition is an important moment to pay attention to cardiovascular health.

What happens to your blood fats (cholesterol and triglycerides) during menopause?

Menopause is associated with significant changes in blood fat levels that may raise the risk of heart disease. Research shows that levels of LDL cholesterol (often called “bad” cholesterol), total cholesterol, triglycerides, and a particle called lipoprotein(a) tend to increase during and after the menopausal transition.^3,4

At the same time, HDL cholesterol (often called “good” cholesterol) may become less effective at protecting arteries, even when its measured level appears stable.⁴

How does estrogen normally protect blood vessels?

Estrogen plays an active role in keeping blood fats at healthy levels. It supports the liver’s ability to clear LDL cholesterol from the blood and helps blood vessels stay flexible and responsive.^1,3,4 When estrogen levels decline at menopause, these processes are disrupted, contributing to a blood fat profile that may increase the risk of plaque building up in arteries.³

Why do these changes happen at menopause and not just with age?

Studies have shown that changes in LDL cholesterol, total cholesterol, and artery structure during the menopausal transition occur independently of chronological aging alone.^1,3 Menopause itself, not just aging, seems to cause important changes in how the body processes fats in the blood. Regular lipid monitoring during and after the menopausal transition is therefore important.

Does your past pregnancy or gynaecological history affect your heart risk at menopause?

Your reproductive history may offer important clues about your future heart health. Several conditions that can occur during pregnancy are now recognised as risk factors for cardiovascular disease later in life and this is an important part of your medical history to share with your healthcare provider.

Women who experienced gestational diabetes, gestational hypertension, or pre-eclampsia during pregnancy have been found to have a higher risk of cardiovascular disease in the years following menopause.^1,5 For example, a diagnosis of gestational diabetes has been associated with a two-fold higher risk of cardiovascular events compared to women without this condition.¹ A history of pre-eclampsia has been linked to longer-term risks including hypertension, coronary artery disease, and stroke.¹

Women who experienced early menopause (before age 45) or premature loss of ovarian function (before age 40) may also face a higher cardiovascular risk, partly because they have had fewer years of estrogen’s natural protective effects.⁵

If any of these conditions apply to you, it is worth discussing your cardiovascular risk proactively with a healthcare professional.

Are hot flushes and other menopause symptoms linked to heart risk?

Some menopause symptoms may be associated with a higher cardiovascular risk though evidence is limited or inconclusive regarding a direct causal link. Hot flushes and night sweats are the most common symptoms of the menopausal transition, affecting up to 80% of women.¹ Research suggests that women who experience frequent or persistent hot flushes may have a less favourable cardiovascular profile, including unfavourable cholesterol levels and higher insulin resistance.¹

What does the research say and what does it not yet prove?

Data from large longitudinal studies, including the Study of Women’s Health Across the Nation (SWAN), suggest that women with frequent and persistent hot flushes may have an increased risk of cardiovascular events compared to those without these symptoms.¹ Sleep disturbances during menopause have been independently linked to markers of cardiovascular risk, such as increased arterial stiffness, a condition in which blood vessels become less flexible, making it harder for blood to flow smoothly and aortic calcification, which refers to calcium buildup in the aorta, the main artery that carries blood from the heart to the rest of the body.²

Depressive symptoms during menopause have also been associated with an increased risk of cardiovascular disease, including coronary artery calcification and cardiovascular mortality.²

These findings do not prove that hot flushes cause heart disease. They may, however, identify women who would benefit from earlier cardiovascular monitoring and lifestyle support. If your symptoms are frequent or severe, discussing them with your healthcare provider is a good opportunity to also check in on your heart health.

How can lifestyle changes protect your heart at menopause?

Healthy lifestyle habits are one of the most powerful tools for protecting the heart at and after menopause. Evidence supports several practical approaches that can meaningfully reduce cardiovascular risk in midlife women.^1,2

What kind of exercise is most supported by evidence?

Regular aerobic exercise such as brisk walking, swimming, or cycling aiming for at least 300 minutes per week of moderate intensity, or 150 minutes of vigorous intensity, is associated with improved cardiovascular health in perimenopausal and postmenopausal women.¹ Muscle-strengthening activities at least twice a week are also recommended.¹ Exercise improves cholesterol levels, lowers blood pressure, reduces insulin resistance, and supports a healthy body weight all of which matter for heart health.¹

Are there dietary patterns linked to better heart health in midlife women?

A diet rich in fruits, vegetables, whole grains, nuts, fish, and olive oil consistent with the Mediterranean or DASH (Dietary Approaches to Stop Hypertension) diet is associated with reduced cardiovascular risk.^1,2 Limiting processed meats, refined carbohydrates, and sweet food and beverages is also recommended.¹ Studies in postmenopausal women have found that healthier dietary patterns are linked to better cholesterol profiles and slower progression of artery changes.¹

Other important steps include stopping smoking, maintaining a healthy body weight, and prioritising good sleep quality.² Smoking is associated with a significantly higher risk of heart disease in women at midlife.¹

Can medications help and why does taking them correctly matter?

Some women may be prescribed medications to help manage cardiovascular risk factors such as elevated cholesterol, high blood pressure, or blood sugar.¹ Whether medication is right for you is a decision your doctor will make based on your individual health history, risk profile, and the results of routine tests.² It is an important conversation to have and not one to delay.¹

When a medication is prescribed, taking it as directed is one of the most important things you can do for your heart.⁵ Missing doses or stopping treatment without medical advice can reduce how well the medication works often in ways that are not immediately obvious.⁵

It is completely normal to have questions or concerns about side effects, cost, or simply remembering to take a pill every day.⁵ These are all valid topics to raise openly with your healthcare provider, who can help you find the best approach for your life. Sharing difficulties honestly is always better than stopping treatment quietly.

Conclusion

The menopausal transition is a meaningful moment for heart health, one that deserves attention and care. The hormonal changes of this period are associated with shifts in cholesterol, blood vessel function, and metabolic health that may increase cardiovascular risk. Understanding these changes, reflecting on your health history, and working with your healthcare provider to build healthy habits and an appropriate monitoring plan are all steps that evidence suggests can make a real difference. Awareness is a powerful first step and it is never too late to start.

FAQ

Q1. At what age does cardiovascular risk start to rise in women?

Cardiovascular risk in women begins to increase notably during the menopausal transition, which typically starts in the mid-to-late 40s. Studies show that rates of cardiovascular disease in midlife women aged 40 to 65 are rising in a way that coincides with the menopausal transition rather than with age alone.¹ Women who experience menopause before age 45 may see this risk increase earlier.^2,5 Discussing your cardiovascular health with your doctor during perimenopause is a good proactive step.

Q2. Does surgical menopause carry more heart risk than natural menopause?

Research suggests that surgical menopause particularly the removal of both ovaries before the age of 45 is associated with a higher cardiovascular risk than natural menopause occurring at a similar age.² This is thought to be due to the abrupt loss of ovarian estrogen production, rather than the gradual decline that occurs with natural menopause.¹ Women who undergo surgical menopause at a younger age have been found to have a higher risk of cardiovascular events compared to those with natural menopause.² If you have had or are considering this type of surgery, discussing cardiovascular risk with your doctor is recommended.

Q3. Does menopause cause changes in body fat that affect heart health?

Menopause is associated with a redistribution of body fat particularly an increase in fat around the abdomen and internal organs.¹ This change in fat distribution is associated with increased insulin resistance, unfavourable cholesterol levels, and a higher risk of cardiovascular disease.^1,4 These changes appear to be driven by the decline in estrogen levels rather than by aging alone.¹ Maintaining a healthy body weight through diet and exercise may help reduce this cardiovascular risk.

Q4. Are the cholesterol changes at menopause different from normal aging?

Yes, research has found that changes in LDL cholesterol, total cholesterol, and artery structure/ stiffness during the menopausal transition are independent of chronological aging. ² This means menopause itself drives specific changes in blood cholesterol and lipids that are distinct from the gradual increases seen with age in both men and women.⁴ The rise in LDL cholesterol during the late perimenopausal and early postmenopausal phases (around 50 years) is particularly pronounced.⁴ Regular lipid monitoring is therefore important during and after the menopausal transition.

Q5. Can I improve my cholesterol through diet alone at menopause?

A healthy diet can contribute meaningfully to better cholesterol levels at menopause. Research in perimenopausal and postmenopausal women has found that dietary patterns consistent with the Mediterranean or DASH diet are associated with improved cholesterol profiles.¹ However, diet alone may not be sufficient for all women, particularly those at higher cardiovascular risk.^3,5 Whether additional medical treatment is needed is a decision for your healthcare provider, based on your individual risk profile.

Q6. Are hot flushes a sign that my heart is at risk?

Hot flushes are not a direct cause of heart disease, but some research suggests they may be associated with a higher cardiovascular risk profile. Data from the SWAN study found that women with frequent and persistent hot flushes had an increased risk of cardiovascular events compared to women without these symptoms.¹ The connection is thought to involve unfavourable cholesterol levels and insulin resistance that can accompany vasomotor symptoms.¹ If your hot flushes are frequent or severe, this is a good opportunity to discuss your cardiovascular health with your doctor. Evidence is limited or inconclusive on whether treating hot flushes directly reduces cardiovascular events.

Q7. Does PCOS affect heart risk at menopause?

Polycystic ovary syndrome (PCOS) has been associated with a higher risk of cardiovascular disease, including ischaemic heart disease.¹ Women with PCOS often have insulin resistance, unfavourable cholesterol levels, and elevated blood pressure all of which can persist into and beyond the menopausal transition.^1,4 Women with a history of PCOS should discuss their cardiovascular risk with a healthcare professional, especially as they approach menopause.

Q8. What is Lipoprotein(a) and why does it matter at menopause?

Lipoprotein(a) also called Lp(a),is a type of fat particle in the blood that is mostly determined by genetics. Higher levels of Lp(a) are associated with an increased risk of cardiovascular disease.⁵ Research suggests that Lp(a) levels may rise after menopause, partly because estrogen appears to suppress its production.⁴ A single measurement is generally sufficient to assess Lp(a) levels, as they remain largely stable over time except during certain life transitions such as the menopausal transition.⁵ If you have not had your Lp(a) checked, it is worth discussing with your doctor, particularly if you have a family history of early heart disease.

Q9. I had gestational diabetes, what does that mean for my heart health now?

A history of gestational diabetes is associated with a significantly higher risk of developing type 2 diabetes and cardiovascular disease later in life.¹ Research suggests this risk is apparent within the first decade after pregnancy and is independent of the development of type 2 diabetes.¹ It is important to share this part of your medical history with your healthcare provider so that appropriate monitoring including regular checks of blood sugar and cardiovascular risk factors can be arranged.

Q10. How do I know if I need medication for my heart health at menopause? Whether medication is appropriate for managing cardiovascular risk at menopause is a decision that depends on your individual risk profile, health history, and the results of routine tests such as cholesterol and blood pressure measurements. Your healthcare provider is the right person to assess this, taking into account both traditional risk factors and any reproductive history that may be relevant.¹ If medication is prescribed, taking it consistently as directed is essential for it to work effectively. Do not hesitate to raise any concerns  about side effects, cost, or other aspects of your treatment with your care team.
