Hypertension- the silent killer!

What is Hypertension?

Blood pressure is the measurement of the pressure or force of blood pushing against blood vessel walls. In hypertension (high blood pressure), the pressure against the blood vessel walls is consistently too high. High blood pressure is often called the “silent killer” because a person with High BP, may not experience any symptoms. It could take years or even decades for the condition to reach levels that are severe enough for the symptoms to become obvious.

When the blood pressure is too high, the heart has to work harder. Over a period of time, uncontrolled high blood pressure makes one susceptible to kidney diseases, stroke and heart ailments. However high blood pressure can be detected easily. And once an individual knows that they have high blood pressure, they can work with their doctor to control it.
