Hypertension:
High blood pressure, medically known as hypertension, is a very common condition
where the force of your blood pushing against the walls of your arteries (the large
blood vessels carrying blood from your heart) is consistently too high. Think of
your arteries like water pipes in your house. If the water pressure inside these
pipes is too high all the time, it can damage the pipes over time. Similarly,
consistently high blood pressure can damage your blood vessels and put a strain on
your heart and other organs.
Hypertension is considered a silent killer because it has visible symptoms until it
cause some major damage like kidney damage or even fatal stroke.
Definition:
Hypertension is a chronic medical condition where the blood pressure in your
arteries is persistently elevated. This consistent high pressure forces your heart
to work harder to pump blood, which can lead to serious health problems over time.
Current Diagnostic Thresholds:
We use two numbers to measure blood pressure (BP):
• Systolic Pressure (Top Number): This is the pressure when your heart
beats and pushes blood out.
• Diastolic Pressure (Bottom Number): This is the pressure when your heart
rests between beats.
According to JNC 8 from the USA and ESC from Europe, which are quite similar
for general purposes:
• Normal Blood Pressure: Less than 120/80 mmHg (read as "120 over 80").
• Pre-hypertension: Systolic between 120-129 mmHg & Diastolic less than 80
mmHg. This is a warning sign.
