Also, when the arteries become narrow or blocked due to the accumulation of plaque, made up of cholesterol, calcium, and fibrous tissue, blood circulation to the arms, legs and brain becomes restricted.
As more plaque builds up, arteries narrow and stiffen. This process is called Atherosclerosis, or “hardening of the arteries.”
When the arteries in the legs and arms become narrow, blocked, and stiffen due to Atherosclerosis, this is a medical condition known as Peripheral Arterial Disease (PAD). And when the arteries that transport blood to the brain become narrow and blocked, this medical condition is known as Carotid Artery Disease.
Peripheral Arterial Disease and Carotid Artery Disease only worsen with time and can become fatal if not treated in time because they can eventually lead to limb loss and stroke.
