What causes a artery to narrow?
The inside wall of a health artery is smooth and firm, letting the blood flow freely. As we age, the arteries may be affected by atherosclerosis – or “hardening of the arteries.” The inner lining of the artery gets thick and rough, with a buildup of cholesterol or fat, like rust in a pipe. This buildup is called “plaque,” and it can cause the artery to get narrow or even close off completely – reducing or stopping the flow of blood. Atherosclerosis can occur in all arteries, but the ones in the heart, neck and legs are the most commonly affected.
