Blood pressure is the pressure on your arteries as your blood is pumped around your body1. Although your blood pressure will vary depending on what you’re doing, if it’s consistently high, you may be told you have high blood pressure or hypertension.
Blood pressure is measured by two numbers, such as 120/80. The larger number is the systolic blood pressure, which is the pressure as your heart pumps blood out.
The lower number is the pressure as your heart relaxes. This is called diastolic blood pressure.
Hypertension is diagnosed when you receive a blood pressure reading on two separate days that shows a systolic reading of equal or over 140/mmHg and/or a diastolic reading of equal or over ≥90 mmHg2.
Over one in five Australians have measured a high blood pressure reading3.
