The World Health Organization (WHO) report that an estimated 1.13 billion peopleTrusted Source have high blood pressure worldwide.
Despite hypertension’s increasing prevalence, it is still widely misunderstood.
First, it is worth outlining what blood pressure is. As the CDCTrusted Source explain, blood pressure is “the pressure of blood pushing against the walls of [the] arteries.”
Blood pressure naturally rises and falls. For instance, it tends to rise during exercise and fall during prolonged rest. However, if blood pressure is elevated for longer periods of time, it increases the risk of various health conditions.
This article will tackle eight persistent myths associated with hypertension.
1. Blood pressure is not serious
Hypertension certainly can be serious. Without treatment, high blood pressure can increase the risk of a range of health issues, includingTrusted Source heart attack, stroke, kidney disease, heart failure, angina, vision loss, sexual dysfunction, and peripheral artery disease.
Hypertension causes damage in a number of waysTrusted Source. For example, over time, increased arterial pressure can cause the vessels to become less elastic. In turn, this reduces the amounts of blood and oxygen that reach the heart, thereby damaging the organ.
High blood pressure can also damage the delicate blood vessels of the brain, which increases the risk that they will block or burst.
2. Hypertension runs in my family, so there is nothing I can do
According to research, hypertension does have a genetic component. For instance, the authors of a 2017 studyTrusted Source that included data from three generations of participants conclude:
“Early onset hypertension in grandparents raises the risk [of] hypertension in grandchildren, even after adjusting for early onset hypertension in parents and lifestyle factors.”
However, hypertension is not inevitable, even for those who may be genetically susceptible to it. Often, the condition develops due to lifestyle factors, such as diet, which genes do not influence.
The authors of a 2018 studyTrusted Source that analyzed genetic, lifestyle, and health data from 277,005 people conclude:
“We show that adherence to a healthy lifestyle (including [healthful] diet, limited alcohol consumption, low urinary sodium excretion, low body mass index [BMI], and increased physical activity) is associated with lower blood pressure regardless of the underlying blood pressure genetic risk.”
They also found that “[a]dherence to a healthy lifestyle is […] associated with [a] lower risk of myocardial infarction, stroke, and composite cardiovascular disease at all levels of underlying blood pressure genetic risk.”
3. High blood pressure is inevitable with age
Hypertension is not inevitable, and it is not a normal part of aging. Although hypertension is more common among older adults, high blood pressure occurs in middle-aged and young adults, too.
Hypertension affects around 7.5% of peopleTrusted Source aged 18–39 years, 33.2% of people aged 40–59 years, and 63.1% of individuals over the age of 60 years.
Despite this increasing prevalence with age, certain lifestyle interventions can significantly reduce the risk of developing high blood pressure. These includeTrusted Source reducing salt intake, exercising regularly, stopping smoking, and eating a healthful diet.

4. I would notice symptoms if I had hypertension
The only way to detect hypertension is to measure blood pressure. There are usually no signs or symptoms to indicate that someone has hypertension.
In the U.S., around 75 million people currently have hypertension. Of these, an estimated 11 million people do not know that they have it.
This is why some experts refer to hypertension as the “silent killerTrusted Source.”
5. I do not use table salt, so I do not need to worry about sodium intake
The WHO recommend consuming under 5 grams of saltTrusted Source each day to help maintain a healthy blood pressure.
They explain that an “estimated 2.5 million deaths could be prevented each year if global salt consumption were reduced to the recommended level.”
However, only avoiding table salt is not sufficient when limiting overall salt intake. It is important to read food labels; salt appears in a wide range of foods, sometimes in very high quantities.
According to the CDC, around 40%Trusted Source of our daily sodium intake comes from these 10 types of food:
• cold cuts and cured meats
• burritos and tacos
• savory snacks, such as chips, popcorn, pretzels, and crackers
Ultraprocessed foods are particularly high in salt. The consumption of these foods — which include soft drinks, chocolate, chips, candy, sweetened breakfast cereals, and packaged soups — may also play a role in the development of other conditions.
For instance, one study in the BMJTrusted Source that included data from more than 100,000 people found that “a 10% increase in the proportion of ultraprocessed foods in the diet was associated with a significant increase of greater than 10% in risks of overall and breast cancer.”
It is also worth noting that both kosher and sea salt are chemically the same as table salt and, therefore, no less harmful to health.
6. When my blood pressure responds to medication, I can stop taking it
People who take medication to treat hypertension may find that their blood pressure returns to normal. However, for many people, hypertension is a lifelong condition.
It is important to follow the doctor’s recommendations and only reduce or stop taking the medication when they have confirmed that this is the best course of action. According to the American Heart Association (AHA)Trusted Source:
“Expect to treat high blood pressure for life. Doctors will sometimes reduce a [person’s] drug dosages after achieving normal blood pressure and maintaining it for a year or more, although it is rare for the treatment to be stopped entirely. Some form of treatment must be continued over a lifetime for good results.”
7. Hypertension is curable
There is currently no cure for hypertension. However, there are ways to manage the condition and reduce its impact on health.
For instanceTrusted Source, making the following changes may help:
• reducing alcohol intake
• eating a healthful diet
• managing stress
• quitting smoking
• maintaining a moderate weight
• taking medication
8. Only men develop high blood pressure
Although anyone can develop hypertension, men have a higher riskTrusted Source of doing so until the age of 45 years. From 45–64 years, everyone has a similar risk of developing high blood pressure.
After the age of 64 years, however, women seem to have a higher risk of developing hypertension than men.
