Understanding Blood Pressure Readings

Blood pressure is a measure of the force exerted by blood against the walls of arteries as it is pumped by the heart. It is expressed in millimeters of mercury (mm Hg) and is measured in two numbers:

* Systolic blood pressure: This is the pressure in the arteries when the heart contracts (beats).

* Diastolic blood pressure: This is the pressure in the arteries when the heart relaxes between beats.

A normal blood pressure reading for an adult is considered to be 120/80 mm Hg or lower. High blood pressure, or hypertension, is defined as a blood pressure reading of 130/80 mm Hg or higher.

What do the numbers mean?

The top number, systolic blood pressure, measures the pressure in your arteries when your heart beats. The bottom number, diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.

Normal blood pressure

Normal blood pressure is considered to be 120/80 mm Hg or lower. This means that your systolic blood pressure is 120 mm Hg or lower and your diastolic blood pressure is 80 mm Hg or lower.

High blood pressure

High blood pressure, or hypertension, is defined as a blood pressure reading of 130/80 mm Hg or higher. This means that your systolic blood pressure is 130 mm Hg or higher or your diastolic blood pressure is 80 mm Hg or higher.

Blood pressure ranges

In addition to normal blood pressure and high blood pressure, there are also other categories of blood pressure readings. These categories are based on the levels of systolic blood pressure and diastolic blood pressure.

The categories are:

* Prehypertension: This is a blood pressure reading of 120-129/80-89 mm Hg. Prehypertension is not a disease, but it is a warning sign that you are at risk for developing high blood pressure.

* Stage 1 hypertension: This is a blood pressure reading of 130-139/80-89 mm Hg. Stage 1 hypertension is a mild form of high blood pressure.

* Stage 2 hypertension: This is a blood pressure reading of 140/90 mm Hg or higher. Stage 2 hypertension is a more severe form of high blood pressure.

What do blood pressure readings mean?

Blood pressure readings can provide information about your heart health. A normal blood pressure reading indicates that your heart is healthy and functioning properly. A high blood pressure reading can indicate that your heart is working harder than it should, which can increase your risk for heart disease, stroke, and other health problems.

If you have high blood pressure, it is important to talk to your doctor about ways to lower it. There are many different treatments available for high blood pressure, including lifestyle changes, medications, and surgery.
