What is Peripheral Artery Disease and what are the warning signs?

Peripheral Artery Disease (PAD) is a circulatory condition where narrowed arteries reduce blood flow to your limbs, usually the legs. This happens when fatty deposits called plaque build up in artery walls, a process called atherosclerosis. PAD affects approximately 8-12 million Americans, particularly those over 65, though many don't recognize their symptoms.
