What is Peripheral Arterial Disease?

Peripheral arterial disease is a common circulatory problem in which narrowed arteries reduce blood flow to your limbs.  When you develop peripheral artery disease, your extremities – usually your legs – do not receive enough blood flow to keep up with demand.  This causes symptoms, most notably leg pain when walking called intermittent claudication. Peripheral artery disease is also likely to be a sign of a more widespread accumulation of fatty deposits in your arteries (atherosclerosis).  This condition may be reducing blood flow to your heart and brain, as well as your legs.
