Blood Pressure: What is it?

Know the Facts

Blood pressure is a measure of how much force the heart is using to pump blood around the body. Your blood pressure can vary throughout the day, and change from day to day. It can also change according to your activity, posture and emotions. These changes are normal if your blood pressure is within the healthy range.

There are two types of blood pressure:

  • Systolic blood pressure (the top number) measures the force of the blood against your artery walls when it’s at its greatest.
  • Diastolic blood pressure (the bottom number) measures the pressure of the blood when the heart relaxes and the force of the blood is at its lowest.

Example: 120 (normal systolic BP, mmHg) / 70 (normal diastolic BP, mmHg)

Having an overly high blood pressure can be harmful. High blood pressure can cause strokes, heart attacks, and heart and kidney failure. It can also be related to dementia and sexual problems. These issues can be prevented if high blood pressure is controlled.


A blood pressure that goes up and stays up above 140 mm Hg (systolic) over 90 mm Hg (diastolic) is considered high blood pressure, also called hypertension.

What Should You Watch Out For?

Watch for These Things

Most people with high blood pressure don’t have any symptoms. However, some people with high BP who do may experience signs like headaches, vision problems, dizziness, or shortness of breath.

When a doctor checks your blood pressure and the reading is high, it doesn’t necessarily mean that you have high blood pressure. It’s only possible to be sure you have high blood pressure after the blood pressure is measured several times in a relaxed setting by a health professional.

Be sure to visit your local drug store to keep an eye on your blood pressure. Use their in-store blood pressure machines to measure your blood pressure and speak with your pharmacist about your results.
