About Blood Pressure
What Is Blood Pressure?
Blood pressure is the force exerted by blood against the walls of the arteries. Systolic pressure occurs when the
heart contracts. Diastolic pressure occurs when the heart expands. Blood pressure is measured in millimeters of
mercury (mmHg). One's natural blood pressure is represented by the fundamental pressure, which is measured
first thing in the morning while one is still at rest and before eating.
What Is Hypertension And How Is It Controlled?
Hypertension, an abnormally high arterial blood pressure, if left unattended can cause many health problems including
stroke and heart attack. Hypertension can be controlled by altering lifestyle, avoiding stress, and with medication under
a doctor’s supervision.
The indicator displays a segment, based on the
current data, corresponding to the WHO classification.
