Common High Blood Pressure Myths

Knowing the facts can help you make smart choices.

One of the best things about educating yourself about high blood pressure, also known as hypertension, is shattering these myths.

Myth: High blood pressure runs in my family. There is nothing I can do to prevent it.

High blood pressure can run in families. If your parents or close blood relatives have had high blood pressure, you are more likely to develop it, too. However, lifestyle choices have allowed many people with a family history of high blood pressure to avoid it themselves.

Myth: I don’t use table salt, so I’m in control of my sodium intake and my blood pressure.

In some people, sodium can increase blood pressure. But controlling sodium means more than just putting down the salt shaker. It also means checking labels, because most of the sodium we consume is hidden in processed foods like tomato sauce, soups, condiments, canned foods and prepared mixes. When buying prepared and prepackaged foods, read the labels. Watch for the words “soda” and “sodium” and the symbol “Na” on labels. These words show that sodium compounds are present.

Myth: I use kosher or sea salt when I cook instead of regular table salt. They are low-sodium alternatives.

Chemically, kosher salt and sea salt are the same as table salt — 40 percent sodium — and count the same toward total sodium consumption. Table salt is a combination of the two minerals sodium (Na) and chloride (Cl). It is not a more healthful option to consume sea or kosher salt than table salt.

Myth: I feel fine. I don’t have to worry about high blood pressure.

Over 100 million U.S. adults have high blood pressure. Many people have high blood pressure for years without knowing it. It’s often called “the silent killer” because it usually has no symptoms. 

You may not be aware that it’s damaging your arteries, heart and other organs. Know your numbers and don’t make the mistake of assuming any specific symptoms will let you know there’s a problem.

Myth: I read that wine is good for the heart, which means I can drink as much as I want.

Heavy and regular use of alcohol can increase blood pressure dramatically. It can also cause heart failure, lead to stroke and produce irregular heartbeats. Too much alcohol can contribute to high triglycerides, cancer, obesity, alcoholism, suicide and accidents. If you drink alcohol, including red wine, do so in moderation. Limit consumption to no more than two drinks per day for men and one drink per day for women. Generally, one drink equals a 12-ounce beer (5% content), an 8-ounce malt liquor (7% content), a five-ounce glass of wine or 1.5 ounces of 80-proof liquor.

Myth: I have high blood pressure and my health care professional checks it for me. This means I don’t need to check it at home.

Because blood pressure can fluctuate, home monitoring and recording of blood pressure readings can provide your health care professional with valuable information to determine whether you really have high blood pressure and, if you do, whether your treatment plan is working. It’s important to take the readings at the same time each day, such as morning and evening, or as your health care professional recommends.

Myth: I was diagnosed with high blood pressure, but I have been maintaining lower readings, so I can stop taking my medication.

High blood pressure can be a lifelong disease. Follow your health care professional’s recommendations carefully, even if it means taking medication every day for the rest of your life. By partnering with your health care team, you can successfully reach your treatment goals and enjoy the benefits of better health.
