Hypertension, also known as high blood pressure, when the force of blood pushes against blood vessel walls. It is dangerous because it makes the heart work harder to pump blood to the body and it contributes to hardening of the arteries or atherosclerosis and the development of heart failure.

  • Understanding the numbers
    • Prehypertension 120 - 139 /80 - 89
    • Borderline 120 - 160 /90 - 94
    • Mild 140 - 160 / 95 - 104
    • Moderate 140 - 180/ 105 - 114
    • Severe 160 + / 115 +


  • What does blood pressure measure?

Each time the heart beats, it sends blood coursing through the arteries. The peak reading of the pressure exerted by this contraction is the systolic pressure. Between beats the heart relaxes, and blood pressure drops. This lower reading is referred to as the diastolic pressure. Blood pressure readings are in millimetres of mercury (mm Hg). A normal blood pressure reading for adults is 120 (systolic)/80 (diastolic). Readings above this level are a major risk factor for heart attack and stroke.
