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.
