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 in the legs 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 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.

PAD is often asymptomatic, meaning the disease does not produce or show any symptoms—at least in the early stages. Even if you’re not experiencing any symptoms, you could still have PAD. This is because your body creates small arteries that re-route blood around the affected vessel. But the body can only do so much, and over time, symptoms become more severe.

When symptoms do occur, they can often be mistaken for other conditions, or as part of the normal aging process. However, ignoring symptoms can lead to further complications. It’s important to see your physician if you believe you could have PAD so you can begin treatment and reduce your risk for complications.
