Peripheral arterial disease (PAD)

Peripheral arterial disease (PAD) is a narrowing or blockage of arteries that causes poor blood flow to your legs or arms.

The most common cause of PAD is the buildup of plaque in blood vessels called "hardening" of the arteries. If you have hardening of the arteries in your legs, you most likely will have it in the arteries of your heart and brain. This increases your chance of having a heart attack or stroke. It can also limit blood flow to the muscles and other tissues of the legs. This can lead to problems with walking or even tissue death.

Treatment for PAD includes ways to relieve symptoms, slow the progress of the disease, and lower your risk of heart attack and stroke.
