About Blood Pressure

The World Health Organization (WHO) and International Society of Hypertension (ISH) jointly developed the following Blood Pressure Classification. This classifi- cation, however, is only a general guidline because your optimum blood preesure depends on your age, morbidity, and treatment strategy by doctor. CONSULT YOUR DOCTOR TO DETERMINE YOUR OPTIMUM BLOOD PRESSURE.

There is not a universally accepted definition of hypotension ( low blood preesure), but a systolic preasure below 100mmHg is usually regarded as hypotension.
