HIGH BLOOD PRESSURE

High blood pressure, or hypertension, is a major risk factor for heart diseases and stroke. Hypertension adds to your heart's workload and damages your arteries and organs over time. Hypertension puts your arteries under constant unnecessary stress, and the same as with a tyre that's been overpumped, too much force inside your blood vessels damages the artery walls and makes them weaker. The build up of various fatty deposits within the arteries is accelerated with high blood pressure, which can break off and cause risk of clogging blood vessels. Left undetected (or uncontrolled), high blood pressure can lead to:

  • Heart attack — High blood pressure damages arteries that can become blocked and prevent blood flow to the heart muscle.
  • Stroke — High blood pressure can cause blood vessels in the brain to clog more easily or even burst. A stroke is a lack of blood flow to a part of the brain, so is primarily caused by blocked or burst blood vessels in the brain.
