Peripheral Artery Disease
Peripheral artery disease (PAD) is a common circulatory problem in which arteries supplying blood to the body’s extremities – arms, kidneys, stomach and, most commonly, the legs – become narrowed or clogged. Blocked blood flow can cause pain when walking or exercising and, if severe enough, can lead to tissue death and even amputation of the foot or leg.
The main risk factor contributing to PAD is smoking. Other factors can include older age, diabetes, high cholesterol, high blood pressure, heart disease and stroke. It is more common in African Americans than other racial groups and is slightly more likely among men than women.
While PAD in itself isn’t life-threatening, it does affect quality of life and can be a symptom of more serious conditions. PAD can lead to stroke, heart attack, open sores that won’t heal, or an infection of your feet or legs. With proper treatment and healthy behaviors, you can improve your chances of preventing – and recovering – from PAD.
