Hypertension is called a “silent killer”, because most people with hypertension are unaware of the problems it causes with no warning signs and symptoms. For this reason, it is essential to keep a tab on your blood pressure on a regular basis.

Hypertension can be a major contributing factor for heart disease and should not be ignored. It is the leading cause of premature death worldwide.

Here’s all you need to know.

High blood pressure – look at the numbers

Blood pressure can be defined as the force of your blood pushing against the walls of the arteries as the heart pumps blood. In case of high blood pressure (hypertension), this force is higher than the normal.

The reading of the blood pressure has two numbers. Top number reads a higher number than the two, called systolic pressure and the bottom is called diastolic pressure. Systolic indicates the pressure in your blood vessels when your heart beats and the diastolic pressure measures the force of blood in your arteries while your heart is relaxed between the beats.

Normal pressure is 120/80 or lower, if the numbers are elevated – it indicates high blood pressure and needs proper medical attention for its management. If the systolic pressure is 180 or higher – it is a medical emergency situation, called “hypertensive crisis” and needs immediate attention.

Why is identifying high blood pressure important?

Many people with hypertension don’t even know they have it. It develops slowly over time and its occurrence can be due to varied underlying causes.

According to WHO, approximately about 46% of the adults are estimated to not know of their diagnosis, and only 1 in 5 adults have their blood pressure in control.

It can be observed in people in late 30s or early 40s. It is common in adults, however, with increasing obesity issues, more and more children are also leaning towards developing high blood pressure.

It is because of these reasons, it is important to identify blood pressure early, so the management is easy. High blood pressure is noted as the primary contributing factors for many diseases. It puts you at an increased risk of heart diseases including heart failure, stroke and other cardiac events.
