What Causes High Blood Pressure?
Blood pressure is only classed as high if it doesn’t go down when you rest. Permanently raised blood pres-
sure can be caused by several factors such as hardening of the arteries, smoking or drinking too much
alcohol. It can also be caused by cholesterol,
a type of fat, building up inside your blood vessels and making them narrower. Being under stress can add
to the problem.
High blood pressure is also known to run in families hence if you find you have a high blood pressure it is a
good idea to test other closely related members of your
family.

Why is it a Good Thing To Measure Blood Pressure at Home?
Having your blood pressure measured by a doctor can cause anxiety which is a cause itself of high blood
pressure. As a variety of conditions affect blood pressure, a single measurement may not be sufficient for
an accurate diagnosis.
The blood pressure measured first thing in the morning after getting up, before eating and while at rest, is
known as the fundamental blood pressure. In practice it is rather difficult to record the fundamental blood
pressure, but it is important to get readings in an environment that is as close as possible to this.
