Hypertension or high blood pressure manifests when the force with which blood pushes the artery walls is consistently too high, resulting in your heart working hard to pump blood.
Blood pressure reading, which tells us how hard your heart is working and how well your blood is flowing through your body, is usually written as two numbers, like 120/80.
The first number is called systolic pressure, which measures the pressure when your heart beats. The second number is diastolic pressure, which measures the pressure when your heart rests between beats. Normal blood pressure is usually around 120/80. If your reading is higher than this, you have high blood pressure.
