The first step in loving your limbs is learning about them. Blood vessels supply oxygen and nutrition to every part of your body, including your legs. When this flow is interrupted due to any number of causes, similar to a clogged pipeline, PAD can occur.
PAD causes arteries to become narrowed or clogged with deposits of plaque. The buildup of plaque causes the arteries to harden, which is called atherosclerosis. When leg arteries are clogged, blood flow to the feet is reduced. Total loss of circulation can cause serious symptoms, including gangrene that can lead to potential amputation.
Plaque buildup can progress over time, increasing the amount of blockage in the artery. Plaque can also trigger the formation of blood clots. A blood clot can further narrow an artery or clog it completely. If a blockage remains in the arteries, it can cause symptoms such as pain, ulcers and difficulty walking.
