The World Health Organization (WHO) and National
High Blood Pressure Education Program Coordinating
Committee have developed a blood pressure standard,
according to which areas of low- and high-risk blood
pressure are identied. This standard, however, is a
general guideline as individual’s blood pressure varies
among different people and different age groups, etc.
It is important that you consult with your physician
regularly. Your physician will tell you your normal
blood pressure range as well as the point at which you
will be considered at risk.
