High Blood Pressure


 
 
Concept Explanation
 

High Blood Pressure

Your heart is the pump that causes your blood to circulate within your body. When your heart beats, it forces blood out of the heart and into blood vessels known as arteries. Your blood is under pressure when it enters your arteries but between heartbeats the pressure in your arteries falls. During exercise your heart works very hard and your blood pressure increases and then falls again when you rest. Therefore, it is normal for your blood pressure to vary throughout the day.

When the pressure in the arteries stays high between heartbeats and during rest, the person is suffering from high blood pressure. High Blood Pressure is also called Hypertension.  The constant high pressure strains the artery walls. It also causes fats from the blood to stick  to the artery walls. The arteries become clogged, causing the heart to pump even harder to get the blood through. This increases the blood pressure further.

Doctors regularly check patients blood pressure symptoms . Without diagnosis, people may not know they have high blood pressure until something major happens such as:

  • Heart attack : When part of the heart muscle is damaged or dies because the blood supply is blocked or severely reduced
  • Stroke : When part of the brain is damaged or dies because the blood supply is blocked or severely reduced.
  •
