Your blood pressure is a measurement of how ‘hard’ your heart is working to push blood around your body, through the blood vessels. The more blood that your heart pumps and the narrower your blood vessels are, the higher your blood pressure will be. It can be a ‘silent’ killer and if you are unaware of your blood pressure then it is worth having it checked by your GP.
How is blood pressure measured?
Blood pressure is recorded as two numbers:
Systolic pressure – the force when your heart contracts and pumps blood
Diastolic pressure – indicates the force used when your heart relaxes and fills with blood
Normal blood pressure is below 120/80 mm Hg. High blood pressure is systolic of 140 or higher and diastolic of 80 or higher.
