Atherosclerosis
is the most common form of arteriosclerosis.
It is caused by a build-up of cholesterol
and calcium deposits
in the lining of arteries.
This narrows the passageway, reducing the flow of blood
through the artery or even blocking it completely. As a result,
atherosclerosis can cause reduced blood supply to the heart
or brain; it can also affect leg circulation, leading to pain
or cramping when walking.
Like other forms of arteriosclerosis, age
factors include age (over 60 years), sex (men are more at
risk than women), obesity, hypertension (high blood pressure),
high blood cholesterol, sedentary lifestyle, and diabetes
mellitus. Treatment may include regular exercise, a diet low
in fat and cholesterol, giving up smoking and avoiding stress.
In more severe cases, a surgical technique may be used to
remove deposits from narrowed arteries (or bypass them altogether)
and improve blood flow.
