What do Blood Pressure Numbers mean?

Blood pressure readings are composed of two numbers and both numbers are an important part of your blood pressure reading. The top number of the reading is referred as systolic pressure and it measures the pressure in your arteries when the heart beats. The bottom number is referred as diastolic pressure and it measures the pressure in your arteries between each heartbeat. The unit of measure for blood pressure is mm Hg which is millimeters of mercury.

Normal Blood Pressure for Adults

According to the American Heart Association (AHA), normal blood pressure for adults (ages 20 and older) is less than 120/80 mm Hg.

Average Blood Pressure by Age

Blood pressure tends to rise as you get older because your blood vessels tend to become stiffer, and plaque (a fatty material) can build up in them. If your blood pressure becomes too high, you're at a greater risk for heart disease, strokes, and more.

According to several researchers, the blood pressure by age is as follows:

For Men:

1. 18-39 years – 119/70 mm Hg

2. 40-59 years – 124/77 mm Hg

3. 60+ years – 133/69 mm Hg

For Women:

1. 18-39 years – 110/68 mm Hg

2. 40-59 years – 122/74 mm Hg

3. 60+ years – 139/68 mm Hg

Blood Pressure Stages

In case of high blood pressure, the blood pressure is divided into stages and at each stage, there is a greater risk to your health. The 4 stages of high blood pressure are:

Elevated : Systolic is 120-120mm Hg/ Diastolic is less than 80mm Hg

Stage 1 hypertension : Systolic is 130-130 mm Hg/ Diastolic is 80-89 mm Hg

Stage 2 hypertension : Systolic is 140 mm Hg and up / Diastolic is 90 mm Hg and up

Hypertensive crisis : Systolic is 180 mm Hg and up / Diastolic is 120 mm Hg and up

When to call your healthcare provider?

Blood pressure above 180/120 mm Hg requires immediate medical attention. Call the doctor even if you experience any of the following symptoms – chest or back pain, difficulty speaking, shortness of breath, vision change, and weakness.

Conclusion

Blood pressure is one indicator of a person’s heart health. If the pressure is too high, it can lead to serious health complications and potentially death.

Though not all causes of elevated blood pressure are preventable, a person can reduce their risk of complications by managing their lifestyle and minimizing risk factors for developing high blood pressure.
