High blood pressure in men is driven by a combination of biology, lifestyle, and age. Testosterone itself plays a direct role in raising blood pressure, which is one reason men develop hypertension earlier and at higher rates than women. By their 40s and 50s, nearly 60% of men have high blood pressure, compared to about 50% of women in the same age range.
How Testosterone Raises Blood Pressure
Men have a built-in risk factor that women largely don’t: testosterone actively increases blood pressure through several mechanisms. Testosterone stimulates a hormone system in the kidneys (the renin-angiotensin system) that controls how tightly blood vessels constrict and how much fluid the body retains. In animal studies, removing testosterone decreased activity in this system, while adding it back cranked it up, raising levels of a powerful vessel-constricting compound called angiotensin II.
That compound triggers a chain reaction. It generates oxidative stress, reduces the availability of nitric oxide (the molecule that relaxes blood vessels), and promotes the production of substances that constrict blood vessels in the kidneys. Testosterone also increases the number of receptors that respond to these vessel-constricting signals, amplifying the effect. This is why men tend to develop high blood pressure about a decade earlier than women, and why the gap between sexes is largest in younger adults. Among 18- to 39-year-olds, 31.2% of men already have hypertension compared to just 13.0% of women.
Visceral Fat and the Belly Problem
Not all body fat affects blood pressure equally. The fat that packs around your organs, called visceral fat, is the type most strongly linked to hypertension in men, and men are far more likely than women to store fat in this pattern. In one study of men with newly diagnosed, untreated high blood pressure, visceral fat mass was 60% larger than in men with normal blood pressure, even when both groups had similar overall body weight and total body fat percentage. Subcutaneous fat (the kind just under the skin) showed no significant difference between the two groups.
The relationship is surprisingly precise: researchers found that each additional kilogram of visceral fat was associated with a 10 mmHg increase in average blood pressure. Visceral fat also worsens insulin resistance, which independently raises blood pressure by affecting how the kidneys handle sodium and how blood vessels respond to signals. This is why waist circumference matters more than the number on the scale. Two men at the same weight can have very different blood pressure profiles depending on where their fat sits.
Diet, Sodium, and Salt Sensitivity
A diet high in sodium and low in potassium is one of the most common and correctable causes of high blood pressure. Most excess sodium comes from processed and restaurant foods, not the salt shaker. But not everyone responds to sodium the same way. About 30% of healthy people are classified as “salt sensitive,” meaning their blood pressure rises significantly more than average in response to high salt intake. Among people who already have hypertension, that figure jumps above 50%.
In salt-sensitive individuals, switching from a very low-salt diet to a high-salt diet raised average blood pressure by roughly 18%, compared to only about 4% in salt-resistant people. Salt sensitivity increases with age in both sexes. If your blood pressure has crept up over the years and you eat a lot of packaged food, sodium is one of the first things worth addressing.
Alcohol Beyond the “Safe” Limit
Moderate drinking is defined as up to two drinks per day for men. Beyond that, the effect on blood pressure becomes significant. Heavy use, meaning four or more drinks a day for men, raises blood pressure both acutely and chronically. Even a single session of binge drinking (five or more drinks within two hours for men) causes a short-term blood pressure spike. Chronic heavy drinking damages blood vessels and can make hypertension resistant to treatment.
Sleep Apnea: A Hidden Driver
Obstructive sleep apnea is far more common in men and is one of the most underdiagnosed causes of high blood pressure. As many as half of all people with sleep apnea have underlying hypertension, and the condition is especially common in men with resistant hypertension that doesn’t respond well to medication.
During sleep, apnea episodes repeatedly cut off oxygen, spike carbon dioxide levels, and jolt the nervous system into a fight-or-flight response dozens of times per hour. This floods the body with stress hormones and vessel-constricting signals throughout the night. Over time, the cumulative effect of this nightly stress spills into the daytime: blood vessels stiffen, inflammation increases, and baseline blood pressure rises even during waking hours. One hallmark is a blood pressure pattern that doesn’t dip during sleep the way it normally should. If you snore heavily, wake up tired, or have a thick neck, sleep apnea is worth investigating as a potential cause of your blood pressure readings.
Work Stress and Long Hours
Working long hours has a measurable effect on blood pressure, and the relationship holds for both men and women. People who work 49 or more hours per week have a 70% greater chance of having masked hypertension (blood pressure that appears normal in a doctor’s office but is elevated the rest of the time) and a 66% greater chance of sustained hypertension compared to those working standard hours. These findings held even after accounting for job strain, suggesting that the sheer volume of hours matters independently of whether the work itself feels stressful.
How Age Compounds the Risk
Blood pressure rises with age in almost everyone, but the trajectory is steeper and starts earlier in men. Among men aged 18 to 39, nearly one in three already has hypertension. By ages 40 to 59, the rate climbs to 59.4%. After age 60, about three-quarters of men have high blood pressure, a rate that finally matches women of the same age. The gap closes because women lose the protective effect of estrogen after menopause, but for men, the damage accumulates over decades. Arteries gradually stiffen, visceral fat tends to increase, and the kidneys become less efficient at managing sodium.
Medications That Raise Blood Pressure
Several common over-the-counter and prescription medications can raise blood pressure, sometimes enough to push borderline readings into hypertension territory. The most relevant for men include:
- Pain relievers like ibuprofen and naproxen: These cause the body to retain water and can affect kidney function, raising blood pressure with regular use.
- Decongestants (pseudoephedrine, phenylephrine): Found in many cold and sinus products, these narrow blood vessels throughout the body, not just in the nose.
- ADHD stimulants: Medications for attention deficit hyperactivity disorder can increase heart rate and blood pressure.
- Caffeine: Causes short-term blood pressure spikes, especially in people who don’t consume it regularly.
- Certain antidepressants: Several classes of antidepressants can raise blood pressure as a side effect.
- Supplements: Ginseng, licorice root, guarana, and ephedra-containing products can all elevate blood pressure.
Recreational drugs including cocaine, amphetamines, and ecstasy cause acute and sometimes dangerous blood pressure spikes.
Blood Pressure Categories to Know
Blood pressure is measured in two numbers: systolic (when the heart contracts) over diastolic (when it rests between beats). Normal is below 120/80. Readings of 120-129 systolic with diastolic still under 80 are classified as elevated. Stage 1 hypertension starts at 130/80, and Stage 2 begins at 140/90 or higher. These thresholds apply equally to men and women, but because men are more likely to hit them earlier in life, regular monitoring starting in your 20s and 30s matters more than many men realize.
