The Causes of Peripheral Arterial Disease

Written by admin


Peripheral Artery Disease is the narrowing of the arteries in a person’s legs, stomach, arms, and head. However, the most common site would be the legs. It is similar to Coronary Artery Disease, both of which are directly caused by atherosclerosis.

Atherosclerosis is the one condition that is usually associated with Peripheral Artery Disease, or PAD. Atherosclerosis causes a buildup in the walls of your arteries due to fatty deposits and plaques. These buildups significantly reduce or even restrict your blood flow, causing more trouble.

Atherosclerosis, although focused on the heart, is a widespread condition. When it affects the arteries supplying the limbs of your body, it results in PAD. Other causes, although relatively uncommon- is the inflammation of the blood vessels, injury to the limbs, or exposure to radiation.


What are the risk factors?

These are the factors that increase a person’s risk of developing PAD. These include:

  • Diabetes
  • Obesity
  • Smoking
  • High Blood Pressure
  • High Cholesterol
  • Old age
  • Family history of PAD, stroke, or any other heart disease
  • High levels of homocysteine

People who have the greatest risk of developing Peripheral Artery Disease are the ones who smoke and have diabetes. This is due to a significant reduction in blood flow.
