About Blood Pressure
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
described in this manual to get to
know your norm al blood pressure.
Regular readings give a more
comprehensive blood pressure
history. Be sure to note the date and
time when recording your blood
pressure. Consult your doctor to
interpret your blood pressure data.
