What Is Blood Pressure?

The heart pumps blood round the body to supply oxygen and other essential nutrients. As the blood is pumped it pushes against the walls of the blood vessels (arteries and veins). The force created by this push is what is referred to as blood pressure. If the pressure is too high it will put a strain on the arteries and the heart this is what constitutes high blood pressure also known as hypertension. Over time this elevated pressure may lead to complications such as heart disease, stroke or kidney diseases.

How can I tell if I have high blood pressure?

When blood pressure is elevated you will not feel sick or notice any changes; there are no signs or symptoms. The only way to know if your blood pressure is elevated is to have it measured.

Blood pressure is measured using a machine that may be manual or electronic. The measurements are given as millimeters of mercury. The pressure reading  is usually given as 2 numbers.

What do the numbers mean?

Blood pressure readings consist of 2 numbers shown as one number on top of the other. The top number is known as the systolic pressure which is the pressure when the heart has contracted and the lower number is the  diastolic pressure which is the lowest level blood pressure reaches when the heart relaxes between beats.

What is normal?

The ideal blood pressure should be below 120/ 80. At this level the risk for heart disease and stroke is significantly reduced.

What is high?

Readings that are consistently above 140/ 90 indicate a diagnosis of hypertension.

Readings that consistently range between 120/80 and 140/90 will be considered to be pre hypertension.

A single reading of an elevated blood pressure does not mean that you are hypertensive. Blood pressure has to be monitored over time to arrive at a conclusion of hypertension.

Blood pressure is considered to be low if it is less than 90/60.

Some people may generally have a low blood pressure. It is however important to talk to your doctor if your blood pressure is low especially if it causes symptoms such as dizziness.
