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.
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
date and time when recording your
blood pressure. Consult your doctor to
interpret your blood pressure data.
