PAD is a narrowing or blockage in the blood vessels in the legs, which slows the blood flow to the legs and feet. It affects as many as 8 to 12 million Americans. When PAD occurs, a lack of blood flow makes it more difficult for wounds or ulcers to heal, because they are not getting the oxygen they need to speed recovery. PAD also raises the risk of heart attack or stroke, just as a blockage in an artery in the heart increases the risk.
