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 normal 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.
