P. A. D. is short for Peripheral Arterial Disease. People have P. A.D. when the arteries in their legs become narrowed or clogged with fatty deposits or plaque (pronounced as 'plak'). The buildup of plaque causes the arteries to harden and narrow, which is called atherosclerosis (pronounced as 'ath-er-o-skle- ro'-sis'). When leg arteries are hardened and clogged, blood flow to the legs and feet is reduced. Some people call this/wor circulation.
P.A.D. occurs most often in the arteries in the legs, but it also can affect other arteries tha carry blood outside the heart. This includes arteries that go to the aorta, the brain, the arms, the kidneys, and the stomach. When arteries inside the heart are hardened or narrowed, it is called coronary artery disease or cardiovascular disease.
The good news is that like other diseases related to the arteries, P.A.D. can be treated making lifestyle changes, by taking medicines, or by having surgery if needed. You can live well with P.A.D.
