High Blood Pressure or medically known as Hypertension is the major risk factor for heart disease, stroke, kidney disease and even eye diseases.  When the blood pressure exceeds a certain threshold we call it as high blood pressure.  Only way to find out what your blood pressure is it must be measured using acceptable measuring devices.   Over a period of time the science has advanced and today blood pressure can be measured at home by yourself (self measurement using home blood pressure monitors).  The cost of electronic blood pressure measuring devices have come down considerably that many people on this planet can own a device.  Unlike any other diseases like head ache or body ache, hypertension has no symptoms and hence it is called the Silent Killer.

Nearly three out of ten people on this planet are living with hypertension.  That is nearly 1.8 billion people have hypertension.  The unfortunate part is nearly 50% of these people are unaware of their condition.  Of those who are aware half of them do not take any action to control their blood pressure either using lifestyle modification or medication.   This means 75% of the world's hypertensive population are at risk and are potential candidates for heart disease, stroke or kidney disease or even sudden death.

Good news is that blood pressure is easily measurable without any discomfort.  The next good news is, once you know you have an elevated blood pressure you can do something to prevent and control rising blood pressure and thus avoid potential risk.

The World Hypertension League (WHL) recommends that everyone should get their blood pressure checked at least once every year.

  • If your blood pressure is below 120/80 (meaning less than 120 mmHg of systolic blood pressure and less than 80 mmHg of diastolic blood pressure) then you have a normal healthy blood pressure.  Congratulations and keep it like that and get your blood pressure checked one year from now.

  • If your blood pressure is less than 140/90 but above 120/80 you are at a risk of becoming hypertensive.  You need to take some immediate steps to improve your lifestyle such as quitting smoking if you are a smoker; reducing your body weight to a healthy level; be more active; improve your dietary habits to include more vegetables and fruits, reduce salt intake and cut down on the amount of fat intake - in other words daily healthy eating pattern; and meet with a health care provider to reassess your blood pressure status every year.

  • If your blood pressure is above 140/90 you need to see a heath care provider to see if you have hypertension and need treatments to help to avoid heart disease and stroke.

The World Hypertension League initiated the World Hypertension Day (WHD) since 2005 to raise public awareness about hypertension throughout the world.  May 17th of every year is celebrated as the WHD by the WHL and all its member country leagues in most parts of the world.  This year, the WHL is launching the WHD 2014 with a theme Know your Blood Pressure and we ask you to participate in a Global Hypertension Awareness Survey.


We ask you to get your blood pressure measured either at home, or at a doctor's clinic or in a community health centre or at your local pharmacy.  Write down you blood pressure and pulse readings - preferably repeated three times, each 2 minutes apart.  Once you have your readings please enter the data and a few simple questions by connecting to the link Survey form . It will take less than 5 minutes of your time.  Some information required on the survey are optional while others are mandatory.  By providing this information you are actually participating in the WHD.  For the first time the WHL is engaging the global population in an interactive manner to raise global awareness of hypertension. 

During the first two weeks of May 2014, we will do an analysis of how many people from each country participated in this survey and how many are in each of the category (normal, potential hypertensives or pre-hypertensives and definite hypertensives) and report on country by country basis on the WHD - May 17, 2014.

We thank you, in advance, for your participation to build a global hypertension awareness survey.
