The following guidelines for assessing high blood pressure (without regard
to age or gender) have been established by the World Health Organization
(WHO). Please note that other factors (e.g. diabetes, obesity, smoking, etc.)
need to be taken into consideration. Consult with your physician for accurate
assessment, and never change your treatment by yourself.
