The Menopause Heart · By Sameer Azhak, MD, FACC
At a Glance
Your artery lining makes nitric oxide, a gas that helps the surrounding muscle relax. Estrogen supports the enzyme that makes it. ¹
Studies have found lower artery-lining function across successive stages of the menopause transition, with differences apparent before periods stop. These are group patterns—not a prediction of what will happen to every woman. ²
In the SWAN Heart Study, large-artery stiffness increased most rapidly around the final menstrual period. Midlife is an important time to reassess cardiovascular risk. ³
Nitrate from vegetables provides another route to nitric oxide, one that does not require the eNOS enzyme. Small trials in postmenopausal women suggest possible vascular benefits, but not a dependable blood-pressure reduction. ⁴⁵
Exercise can lower blood pressure after menopause. ⁶ Sleep, sodium, and recovery from stress deserve attention too. ⁷⁸⁹
Hormone therapy is a separate, individualized decision. It is not prescribed as a blood-pressure treatment or approved to prevent cardiovascular disease. Do not stop prescribed treatment because you change your diet or routine. ¹⁰
“My blood pressure was always fine. Why is it climbing now?”
It is a question many women ask in their forties and fifties.
Age is part of the answer. So are weight, sleep, stress, sodium, and family history. But another part of the story sits inside your blood vessels, in a system most people have never heard of.
In the companion article in The Integrative Cardiologist, “Nitric Oxide: Your Body’s Natural Blood Pressure Biohack,” I described the artery lining as a pharmacy that produces some of its own blood-pressure medicine: a gas called nitric oxide.
We’ve already talked about magnesium, sleep, exercise, and other parts of a blood-pressure plan. This article builds on that foundation, with a closer look at what changes at midlife.
For decades, that pharmacy had a coworker.
That coworker was estrogen.
During perimenopause, estrogen levels fluctuate. After menopause, estradiol—the principal estrogen during the reproductive years—remains much lower. Its support for the blood vessels changes along the way. ¹
This article is about that changing partnership—and how to support the work it used to share.
It is not a claim that estrogen explains every rising reading, or that you can replace it with a beet shot.
Two roads, briefly
The endothelium is the thin layer of cells lining your arteries.
Those cells contain an enzyme called eNOS. It uses the amino acid arginine to produce nitric oxide. The gas moves into nearby muscle cells and helps the artery relax. ¹¹
Your body has two routes to the same gas:
The enzyme road: eNOS produces nitric oxide inside the lining. Blood flow, including the increased flow during exercise, helps activate it. ¹¹
The nitrate road: nitrate from foods such as leafy greens and beets is converted by mouth bacteria into nitrite. Your body can then convert nitrite into nitric oxide. ¹²
The second route does not require eNOS. That does not mean hormones have no influence anywhere along the pathway. It means the body has another way to support nitric-oxide availability.
That distinction becomes interesting when estrogen’s support for the enzyme road declines.
What estrogen was doing all along
Estrogen is not only a reproductive hormone.
Blood-vessel cells carry estrogen receptors, and estradiol can activate signaling that supports eNOS and nitric-oxide production. ¹
So what changes during the transition?
In a study of 132 healthy women, researchers measured flow-mediated dilation—how well the arm artery widens after a cuff is released.
Average artery-lining function was lower across successive stages: premenopause, early perimenopause, late perimenopause, early postmenopause, and late postmenopause. ²
The researchers compared different women at different stages. They did not follow the same women through every stage, so age and other differences remain important when interpreting the pattern.
Still, the differences were apparent before periods stopped.
An experiment that helped explain the connection
A later study briefly suppressed ovarian hormones in healthy women.
Artery-lining function declined in premenopausal and perimenopausal participants. Adding estradiol back reversed that impairment. The experiment supports a role for estradiol in maintaining vascular function; it does not establish that hormone therapy prevents heart attacks. ¹³
The same research implicated oxidative stress—reactive molecules that can interfere with nitric oxide.
An intravenous vitamin C infusion improved artery-lining function in women in late perimenopause and postmenopause at baseline, but not in women earlier in the transition. ¹³
Other experiments have examined BH₄, a helper molecule eNOS needs to function properly. Supplementing it temporarily improved vascular measurements in estrogen-deficient postmenopausal women. ¹⁴
These were experiments designed to understand the biology—not evidence that BH₄ or antioxidant supplements should become part of your routine.
In pharmacy terms, the coworker’s support declined, and the conditions that kept production running smoothly changed.
Stiffer arteries, faster
Artery-lining function is not the only change.
In the SWAN Heart Study, stiffness of the large arteries increased most rapidly within about one year of the final menstrual period, compared with the years before and after. ³
Stiffness and endothelial function are related, but they are not the same measurement. Neither tells the whole story of your cardiovascular risk.
The American Heart Association identifies the menopause transition as an important period for prevention and reassessment. ¹⁵
That means looking at blood pressure, cholesterol, glucose, smoking, activity, sleep, and your medical and pregnancy history—not simply checking an estrogen level.
Perimenopause deserves attention. It is not a deadline after which prevention stops working.
Signals worth noticing
Hot flashes
Studies have linked hot flashes with poorer artery-lining function in some midlife women, particularly younger participants. ¹⁶
That does not prove hot flashes damage arteries, and a hot flash is not a diagnostic test for heart disease.
It is another reason not to dismiss the transition as “just symptoms.” If flashes are frequent or disruptive, discuss them—and know your cardiovascular risk factors.
Sodium
In a small study of women undergoing surgical menopause, the proportion whose blood pressure was sensitive to sodium more than doubled within months of surgery. ⁸
Surgical menopause is abrupt. That finding should not be assumed to describe every woman going through natural menopause.
The practical point is simpler: take another look at sodium, even if it never seemed to affect your pressure before.
Start with packaged foods, restaurant meals, sauces, and prepared snacks—not only the saltshaker.
Sleep
In a randomized crossover study, healthy women who delayed bedtime by about an hour and a half for six weeks developed poorer artery-lining function. ⁷
A companion analysis found increased oxidative stress in endothelial cells. ¹⁷
The study was not specifically a menopause trial. But it shows why routinely sacrificing sleep deserves attention as part of vascular care.
Protecting sleep is not always as simple as choosing an earlier bedtime. Hot flashes, insomnia, caregiving, shift work, and breathing problems may need their own solutions.
Another road: beets and leafy greens
The nitrate pathway offers another way to support nitric-oxide availability when the enzyme pathway is less effective.
The direct evidence in postmenopausal women is small—but worth understanding.
What the trials actually found
Seven days of beetroot juice: In a crossover trial analyzing 24 healthy postmenopausal women, nitrate-rich juice produced a favorable difference in the change in resting artery-lining function compared with placebo. However, the finding was not consistent across all analyses. Blood pressure did not change. The juice also did not protect against a laboratory blood-flow-interruption challenge when tested about 24 hours after the final dose. ⁴
Twelve weeks of beetroot extract: In a trial of 20 postmenopausal women aged 60–85, nitrate-rich extract improved several measurements of carotid artery stiffness. Blood pressure remained unchanged. ⁵
These findings suggest possible vascular benefits. They do not establish that a daily beet product prevents heart attacks, reverses menopause-related changes, or reliably lowers blood pressure.
That distinction matters: a favorable laboratory measurement is a clue, not the same thing as a proven clinical outcome.
Start with vegetables
Arugula, spinach, lettuce, and beets are useful nitrate sources. ¹²
In a large Danish cohort, higher vegetable-nitrate intake was associated with lower blood pressure and less cardiovascular disease. The association with lower cardiovascular risk appeared to level off at a moderate intake. Because the study was observational, it cannot prove nitrate caused the benefit. ¹⁸
The practical approach does not require you to calculate nitrate milligrams at dinner.
Add vegetables regularly. Choose varieties you enjoy. Think about the whole eating pattern—not just one molecule.
Mouthwash: ask, do not abruptly stop
Mouth bacteria help convert nitrate to nitrite.
In a small experiment, chlorhexidine mouthwash reduced oral nitrite production and raised blood pressure by a few points. Pooled studies have been less consistent. ¹⁹²⁰²¹
Do not throw out a rinse your dentist prescribed.
If you use a strong antiseptic rinse daily out of habit, ask whether you need it. Oral health belongs in the plan too.
Concentrated products are a separate choice
A beet shot is not interchangeable with a serving of greens.
If you consider juice, shots, or powders:
Check the serving size and sugar content.
Recognize that nitrate content varies among products. ²²
Discuss regular concentrated use with your clinician, particularly if you take blood-pressure medicine.
Do not assume that the results from a short trial establish the benefits of indefinite use.
Vegetables first. Concentrated products, when appropriate, deserve a separate discussion.
Garlic, sugar, and soy
Garlic
Garlic supplements can lower blood pressure in people with hypertension, but studies test specific preparations. The general hypertension evidence does not establish a menopause-specific benefit. ²³
Use garlic in cooking because you enjoy it.
If you consider a supplement, review bleeding risk, planned procedures, and your medicines with your clinician or pharmacist—especially if you take a blood thinner. ²⁴
The TIC companion explains why crushed garlic, aged garlic extract, and garlic tablets are not interchangeable interventions.
Added sugar
Large fructose loads can increase uric-acid production and may interfere with nitric-oxide signaling through several experimental mechanisms. That is not a reason to avoid ordinary portions of whole fruit. ²⁵²⁶
The practical target is excess added sugar, especially sweetened drinks. ²⁶
Replace the soda or sweetened tea before worrying about the apple.
Soy
Because soy isoflavones interact with estrogen receptors, women often ask whether soy can replace estrogen’s vascular effects.
The trial evidence is mixed. Analyses have reached different conclusions about improvements in artery-lining function. ²⁷²⁸
Soy foods can fit into a healthy eating pattern. They are not a proven replacement for estrogen’s vascular effects, and that is not a reason to start an isoflavone supplement.
I am often asked about the safety of Soy foods as it relates to cancer risk and thyroid health. My response has always been:
As part of an anti-inflammatory diet, it’s desirable to regularly include whole soy foods for general health purposes and avoid soy isolates. The isoflavones - genistein, daidzein and glycitein are also referred to as phytoestrogens. Their delicate balance in natural whole soy foods do not translate in soy isolates. These compounds are known to be both pro-estrogenic and anti-estrogenic depending on target tissue.
Movement: why it still works
Exercise increases blood flow along the artery lining. That flow helps activate eNOS. ¹¹
After menopause, the research has an interesting wrinkle.
In one trial, 12 weeks of aerobic training improved artery-lining function in postmenopausal women receiving estradiol, but not in those receiving placebo. ²⁹
That does not mean exercise stopped working. It means one vascular outcome responded differently under the conditions of that trial.
A systematic review of randomized trials in postmenopausal women with elevated blood pressure found that exercise training lowered pressure and improved measures of arterial stiffness. Results varied substantially among studies, so the average is not a personal forecast. ⁶
Exercise influences blood pressure through many pathways—not only nitric oxide.
Start where you are
Choose an aerobic activity you can repeat: walking, cycling, swimming, or another suitable option.
Add strength work appropriate to your health and abilities.
Consider guided isometric training if it suits your medical history and joints.
During isometric holds, breathe continuously. Do not strain while holding your breath.
If your pressure is uncontrolled, or you have cardiovascular disease or concerning symptoms, agree on a starting plan with your clinician. ³⁰
Perimenopause is an important time to build the habit.
If you are already well past menopause, you have not missed your chance.
Breathing: an optional practice, not a replacement treatment
The breathing practice I recommend is Dr. Andrew Weil’s 4-7-8 breath, also called the Relaxing Breath.
I offer it as a tool for relaxation—not as a treatment for hypertension or a way to replace estrogen.
Here is the beginner routine, adapted from Dr. Weil’s instructions: ³¹
Sit comfortably with your back straight.
Rest the tip of your tongue against the ridge just behind your upper front teeth.
Exhale through your mouth with a whoosh.
Close your mouth and inhale quietly through your nose for a count of four.
Hold for a count of seven.
Exhale through your mouth for a count of eight.
Repeat for a total of four breaths.
Dr. Weil recommends practicing twice daily and limiting the routine to four breaths at a time during the first month. The counts describe a ratio, not necessarily seconds. ³¹
Do not force the hold. If you become lightheaded, short of breath, or uncomfortable, stop and return to normal breathing. If the pattern does not suit you, a gentle breathing practice without a prolonged hold may be more comfortable.
What does the research show?
Evidence for this specific technique is limited.
In a study of 43 healthy adults aged 19–25, a session was followed by lower heart rate and systolic pressure. Participants performed three sets of six cycles—more than the beginner routine above. The study did not establish a lasting blood-pressure benefit or effectiveness in menopausal women. ³²
Both groups performed the breathing exercise; there was no comparison group that simply rested without it.
It also did not test whether the breathing session increased nitric oxide. ³²
A review of device-guided slow breathing did not establish a significant blood-pressure reduction compared with controls. That is a different intervention, but it reinforces the need not to promise a treatment effect from a breathing exercise. ³³
You can still find the practice useful.
It gives you something simple to do during an upsetting moment, at bedtime, or between the demands of a long day. Whether it helps you feel calmer is a different question from whether it treats hypertension.
Yoga, tai chi, and meditation
Small studies in postmenopausal women have reported favorable vascular findings with yoga incorporating breathing techniques and with tai chi. These results need confirmation. ³⁴³⁵
The American Heart Association has described meditation as a possible addition to standard cardiovascular risk reduction, while emphasizing the limitations of the evidence. ⁹
Choose a practice you enjoy and can sustain. You do not need to prove it raises nitric oxide to find it worthwhile.
It remains an addition to the plan—not a substitute for sleep care, activity, or prescribed treatment.
Where hormone therapy fits
The biological story naturally raises a question:
“If estrogen helped, should I replace it?”
That decision cannot be made from an artery measurement alone.
Hormone therapy is not approved for primary or secondary prevention of cardiovascular disease. It is not prescribed as a blood-pressure treatment. ¹⁰
The 2022 North American Menopause Society statement describes a generally favorable benefit-risk balance for treating bothersome menopausal symptoms and preventing bone loss in appropriately selected women younger than 60 or within 10 years of menopause onset, provided they have no contraindications. ¹⁰
Your formulation, route, dose, medical history, and treatment goals matter. The balance should be reassessed over time.
The approach to premature or early menopause may differ; it deserves its own individualized discussion. ¹⁰
You can discuss hormone therapy and improve your blood-pressure plan in parallel. One conversation should not replace the other.
Putting it together
A practical midlife pattern might look like this:
Add leafy greens or beets to meals regularly.
Use garlic in cooking because you enjoy it.
Replace sweetened drinks with water, unsweetened tea, or sparkling water.
Take a fresh look at sodium.
Seek help for sleep that remains disrupted.
Walk or do another suitable aerobic activity regularly.
Add strength work and, when appropriate, guided isometric training.
Practice 4-7-8 breathing if it feels comfortable, or choose another way to recover from stress.
You cannot add the study results together to predict your response.
Your starting pressure, health, medicines, and the changes you can sustain all matter.
And not every barrier is under your control. Caring for your health should not become another reason to blame yourself.
How to tell whether it is helping
Use a validated upper-arm monitor, the correct cuff size, and a consistent measurement routine. Compare averages over several days rather than reacting to one reading. ³⁶
For a step-by-step approach, see the plan in Lower Your Blood Pressure.
What this does not replace
If you need medication now, take it.
A healthier routine may create an opportunity to simplify treatment later. That decision follows measurements and a clinical review—not the purchase of a supplement.
I explain that conversation in “Do I Have to Take Blood Pressure Medication for the Rest of My Life?”
The work she shared
So why is your blood pressure climbing now?
There may be several contributors. Estrogen’s support for the artery lining changes during the menopause transition, but these studies do not show how much that change explains any one woman’s blood pressure.
But estrogen was a coworker, not the whole pharmacy.
Vegetables offer another route to nitric oxide. Exercise still helps control pressure. Sleep, sodium, and recovery from stress deserve a place in the plan.
These are opportunities—not a promise that you can manage every change on your own.
Perimenopause is an important time to pay attention. If you are further along, you have not missed your chance.
Keep taking treatment you need.
If your readings improve, bring the log. That is how we decide together whether the plan can become simpler.
This post is for general educational purposes only. It is not medical advice, is not a substitute for care from your own physician, and does not create a physician-patient relationship. Do not start, stop, or change any treatment based on what you read here. If you think you may have a medical emergency, call 911 or go to the nearest emergency department.
