What Causes High Blood Pressure?

Blood pressure is the measure of the force of blood pushing against blood vessel walls. The heart pumps blood into blood vessels, which carry the blood throughout the body. High blood pressure, also called hypertension, is dangerous because it makes the heart work harder to pump blood out to the body and contributes to hardening of the arteries, or atherosclerosis, to stroke, kidney disease, and to heart failure.

What Is “Normal” Blood Pressure?

A blood pressure reading is written like this: 120/80. It’s read as “120 over 80.” The top number is called the systolic, and bottom number is called the diastolic. The ranges are:

  • Normal: Less than 120 over 80 (120/80)
  • Elevated: 120-129/less than 80
  • Stage 1 high blood pressure: 130-139/80-89
  • Stage 2 high blood pressure: 140 and above/90 and above
  • Hypertension crisis: higher than 180/higher than 120 — See a doctor right away

If your blood pressure is above the normal range, talk to your doctor about how to lower it.

What Causes High Blood Pressure?

The exact causes of high blood pressure are not known, but several things may play a role, including:

Essential Hypertension

In as many as 95% of high blood pressure cases in the U.S., the underlying cause can’t be found. This type of high blood pressure is called “essential hypertension.”

Though essential hypertension remains somewhat mysterious, it has been linked to certain risk factors. High blood pressure tends to run in families and is more likely to affect men than women. Age and race also play a role. In the United States, blacks are twice as likely as whites to have high blood pressure, although the gap begins to narrow around age 44. After age 65, black women have the highest incidence of high blood pressure.

Essential hypertension is also greatly influenced by diet and lifestyle. The link between salt and high blood pressure is especially compelling. People living on the northern islands of Japan eat more salt per capita than anyone else in the world and have the highest incidence of essential hypertension. By contrast, people who add no salt to their food show virtually no traces of essential hypertension.

Most people with high blood pressure are “salt sensitive,” meaning that anything more than the minimal bodily need for salt is too much for them and increases their blood pressure. Other factors that can raise the risk of having essential hypertension include obesitydiabetes; stress; insufficient intake of potassiumcalcium, and magnesium; lack of physical activity; and chronic alcohol consumption.
