How? copyright 2011 Wohers iower Heath l Upeinoon wasma is wkinsExplanation / Answer
Peripheral artery disease (PAD) is caused by arteriosclerosis, or "hardening of the arteries." This problem occurs when fatty material (plaque) builds up on the walls of your arteries and makes them narrower. The walls of the arteries also become stiffer and cannot widen (dilate) to allow greater blood flow when needed.
As a result, the muscles of your legs cannot get enough blood and oxygen when they are working harder (such as during exercise or walking). If PAD becomes severe, there may not be enough blood and oxygen, even when the muscles are resting. Peripheral artery disease is a common disorder. It most often affects men over age 50, and women can have it as well.
The main symptoms of PAD are pain, achiness, fatigue, burning, or discomfort in the muscles of your feet, calves, or thighs. These symptoms usually appear during walking or exercise, and go away after several minutes of rest.
At first, these symptoms may appear only when you walk uphill, walk faster, or walk for longer distances.
Slowly, these symptoms occur more quickly and with less exercise.
Your legs or feet may feel numb when you are at rest. The legs also may feel cool to the touch, and the skin may look pale.
Peripheral vascular disease (PVD) might also be the problem the lady is suffering from. This involves damage to or blockage in the blood vessels distant from the heart
