Blood Pressure 101

Blood is carried from the heart to all parts of your body in vessels called arteries.  So what is blood pressure? Blood pressure is the force of the blood pushing against the walls of the arteries each time the heart beats (about 60-70 times a minute at rest).

Systolic (top number): Your blood pressure is at its highest when the heart beats, pumping the blood.

Diastolic (bottom number): When your heart is at rest, between beats, your blood pressure falls

High blood pressure is considered a reading of 140/90 or higher and is a serious problem to have. High blood pressure is often called the “silent killer” because it usually has no symptoms. Some people may not find out that they have it until they have trouble with their heart, brain or kidneys. Nearly 1 in 3 American adults has high blood pressure.

How Can I Track My Blood Pressure?

•       Visit your local pharmacy.  Walgreens, CVS, and many local grocery stores with pharmacies have free blood pressure check stations.

•       Write down your blood pressures in a log or download a user friendly application on your phone.

Some people’s blood pressure is high only when they visit the doctor’s office.  This condition is called “white coat” hypertension.
