About Blood Pressure
1. 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 taking food or drink.
2. What is hypertension and how is it controlled?
Hypertension is abnormally high blood pressure. If left unattended, it 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 help prevent hypertension or keep it under control:
• Do not smoke.
• Reduce salt and fat intake.
• Maintain proper weight.
• Exercise regularly.
•
Have regular physical checkups.
3. Why measure blood pressure at home?
Blood pressure measured at a clinic or doctor's office may cause apprehension
or fear 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.
