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.
To prevent hypertension or keep it under control:
Do not smoke Exercise regularly
Reduce salt and fat intake Have regular physical checkups
Maintain proper weight
Why Measure Blood Pressure At Home?
Blood pressure measured at a clinic or doctor's office may cause
apprehension and can produce an elevated reading, 25 to 30 mmHg higher
than that measured at home. Home measurement reduces the effects of
outside influences on blood pressure readings, supplements the doctor's
readings and provides a more accurate, complete blood pressure history.
WHO Blood Pressure Classification
Standards to assess high blood
pressure, without regard to age,
have been established by the
World Health Organization
(WHO), as shown in the chart.
Blood Pressure Variations
An individual’s blood pressure
varies greatly on a daily and
seasonal basis. It may vary by
30 to 50 mmHg due to various
conditions during the day. In hypertensive individuals’ variations are
even more pronounced. Normally, the blood pressure rises while at work
or play and falls to its lowest levels during sleep. So, do not be overly
concerned by the results of one measurement.
Take measurements at the same time every day using the procedure
