    Blood pressure is measured by how hard your blood presses against your blood vessels as it travels through the body. Blood pressure rises when blood is met with greater resistance in the blood vessels (caused by narrower blood vessels).  This is because your heart has to work much harder to pump blood out to the body.

    High blood pressure (also called hypertension) is dangerous because the extra stress placed on your heart can lead to a heart attack, a stroke (when blood flow to the brain is cut off), and many other health problems. No one knows for sure what causes high blood pressure, but there are known risk factors. These include:
