WHAT IS BLOOD PRESSURE?
Blood pressure is the pressure that your circulating blood places on the walls of your arteries as it travels around your body.
High blood pressure (Hypertension) puts extra strain on your arteries and organs and over time this can lead to serious and potentially life-threatening issues such as heart attacks and strokes.
Low blood pressure (Hypotension) is generally less serious but may cause lightheadedness and dizzy spells.
For most people high blood pressure has no noticeable symptoms, approximately one third of people who have it are unaware. A blood pressure test takes minutes and could save your life.
