Blood Pressure

February is American Heart Month, so if knowledge is power, you’re about to be nearly invincible with your powerful knowledge about blood pressure.

What is blood pressure?

When the heart pumps blood through the arteries, the blood puts pressure on the artery walls. This is known as blood pressure. Blood pressure is the pressure of blood pushing against the walls of your arteries. Arteries carry blood from your heart to other parts of your body. Your blood pressure normally rises and falls throughout the day.

What do blood pressure numbers mean?

Blood pressure is measured using two numbers:

• The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats.
• The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.

What are normal blood pressure numbers?

A normal blood pressure level is less than 120/80 mmHg. No matter your age, you can take steps each day to keep your blood pressure in a healthy range.

What is high blood pressure (hypertension)?

High blood pressure, also called hypertension, is blood pressure that is higher than normal. Your blood pressure changes throughout the day based on your activities. Having blood pressure measures consistently above normal may result in a diagnosis of high blood pressure (or hypertension).

The higher your blood pressure levels, the more risk you have for other health problems, such as heart disease, heart attack, and stroke.

Your health care team can diagnose high blood pressure and make treatment decisions by reviewing your systolic and diastolic blood pressure levels and comparing them to levels found in certain guidelines.

What are the signs and symptoms of high blood pressure?

High blood pressure usually has no warning signs or symptoms, and many people do not know they have it. Measuring your blood pressure is the only way to know whether you have high blood pressure.

What causes high blood pressure?

High blood pressure usually develops over time. It can happen because of unhealthy lifestyle choices, such as not getting enough regular physical activity. Certain health conditions, such as diabetes and having obesity, can also increase the risk for developing high blood pressure. High blood pressure can also happen during pregnancy.

You can manage your blood pressure to lower your risk for serious health problems that may affect your heart, brain, kidneys, and eyes.resize iconView Larger

What problems does high blood pressure cause?

High blood pressure can damage your health in many ways. It can seriously hurt important organs like your heart, brain, kidneys, and eyes. The good news is that, in most cases, you can manage your blood pressure to lower your risk for serious health problems.

How do I know if I have high blood pressure?

There’s only one way to know if you have high blood pressure: Have a doctor or other health professional measure it. Measuring your blood pressure is quick and painless. Talk with your health care team about regularly measuring your blood pressure at home, also called self-measured blood pressure (SMBP) monitoring. High blood pressure is called the “silent killer” because it usually has no warning signs or symptoms, and many people do not know they have it.

What can I do to prevent or manage high blood pressure?

Many people with high blood pressure can lower their blood pressure into a healthy range or keep their numbers in a healthy range by making lifestyle changes. Talk with your health care team about

• Getting at least 150 minutes of physical activity each week (about 30 minutes a day, 5 days a week)
• Not smoking
• Eating a healthy diet, including limiting sodium (salt) and alcohol
• Keeping a healthy weight
• Managing stress

Talk with your health care team right away if you think you have high blood pressure or if you’ve been told you have high blood pressure but do not have it under control.

By taking action to lower your blood pressure, you can help protect yourself against heart disease and stroke, also sometimes called cardiovascular disease.
