Dr.James Sebastian- the best physician in Kochi explains the silent killer which we call hypertension.Hypertension, more commonly known as high blood pressure, is a very treacherous condition in which blood pressure increases to unhealthy levels. As a result of the blood putting high pressure on the walls of arteries, the arteries harden. This increases the amount of resistance the blood meets while the heart is pumping and makes our hearts work harder. If hypertension is left untreated over a long period of time, it will cause progressive changes in the blood vessel walls and the heart. This ultimately results in permanent destruction. In the majority of the cases, we will only come to know of this when a catastrophic event like a heart attack or stroke presents itself for the first time. Hence, it’s always better to keep a close eye to catch the disease early.
