High blood pressure, also known as Hypertension, is often called “silent killer”. The symptoms of high blood pressure are very rare in the early stages, and most patients are not aware of their elevated blood pressure level. However, hypertension or high blood pressure can lead to huge damage towards our health. The World Health Organization (WHO) has stated that high blood pressure has become the second largest risk factor affecting death rate globally. The number of people suffering from hypertension worldwide is up to 1.28 billion, and the complications from hypertension account for 9.4 million deaths worldwide every year. In Malaysia, the proportion of adults suffering from high blood pressure has exceeded 30%, and approximately three out of five of them are not aware of their high blood pressure problems. Due to the diet choices and living habits, the trend of hypertension in adults below age of 40 are gradually increasing. Therefore, we should monitor our blood pressure level regularly, especially if you have a family history of hypertension.
