What menopause has to do with your blood pressure

As we mark World Hypertension Day on 17 May, it’s time to shine a light on a lesser-known, but hugely important, health issue for women: the link between menopause and high blood pressure.

Here in South Africa, women are facing alarmingly high rates of hypertension, and experts are calling for a fresh, more female-focused approach to heart health. Think beyond treatment… it’s about prevention, lifestyle support, and a better understanding of what’s really going on in women’s bodies.

While men’s blood pressure tends to creep up steadily from their 20s, women face unique hurdles. Pregnancy complications like gestational hypertension can leave lasting effects, and the real kicker often comes around menopause.

“Even in women with no family history of high blood pressure, experiencing it during pregnancy significantly increases their risk later in life,” explains Ingrid Singels, Marketing Manager of Pharma Dynamics’ Scientific Division.

So, what’s the menopause connection? Blame the hormonal shift.

“After menopause, the drop in oestrogen reduces nitric oxide, which normally helps keep blood vessels relaxed and leads to increased blood pressure,” says Singels. “This is why postmenopausal women often display higher systolic blood pressure than men of the same age, along with stiffer arteries and increased renin-angiotensin system activity contributing to this shift.”

It’s not just anecdotal. A review in the Netherlands Heart Journal found that 30–50% of women develop hypertension before age 60, with menopause-related changes like central fat gain, rising insulin resistance and diabetes playing a role.

In South Africa, the numbers tell a worrying story. Hypertension among women jumped from 31% in 1998 to a staggering 48% in 2016. Poor dietary habits – think sugar-laden drinks, processed foods and salty snacks – have all contributed to rising obesity levels, especially in women.

A 2020 study of South African adults found that women with higher waist-to-hip ratios were 1.75 times more likely to have hypertension, while those with diabetes were three times more likely to be affected.

Then there’s the issue of access. Socioeconomic gaps often mean women can’t always get the check-ups, nutritious food or follow-up care they need. Public health experts say that if we want to tackle this crisis, we need solutions designed specifically for women; not just scaled-down versions of what works for men.

And it’s not just about risk. Women also react differently to hypertension medication.

A 2022 study from the University of Chicago found that women experience nearly double the number of adverse drug reactions as men – thanks to sex differences in how drugs are absorbed and metabolised. Diuretics can cause electrolyte imbalances, while ACE inhibitors are known to trigger a stubborn cough in many female patients.

“Many antihypertensive drugs were tested predominantly on men and therefore might not be fully optimised for women’s physiology,” says Singels. “This makes lifestyle changes, such as reducing salt intake, healthy eating, regular exercise, stress management, quitting smoking, limiting alcohol consumption and ensuring adequate sleep essential components of hypertension management in women.”

And don’t forget those regular check-ups.

“It’s also crucial for women to engage in regular screenings, including blood pressure and cholesterol monitoring,” Singels adds. “Your healthcare practitioner should also check for hormonal fluctuations, which can affect blood pressure.”

As more women enter midlife, there’s growing recognition that we need better research, more education, and smarter, gender-sensitive care plans. With early detection, personalised treatment, and healthy lifestyle changes, we can make real progress in reducing the impact of hypertension on South African women.

Because when it comes to heart health, one size definitely doesn’t fit all.
