Dr. Chris LesarQ: What is carotid artery disease?
A: The disease occurs when the major arteries in your neck – which supply blood to your brain – become narrowed or blocked. The carotid arteries extend from your chest to the brain. As you age, a sticky substance called plaque – made up of cholesterol, calcium and fibrous tissue – can build up in the walls of your arteries. As more builds up, your arteries narrow and stiffen, leading to a process called atherosclerosis, or hardening of the arteries. A blocked carotid artery is a major risk for stroke. Ways to prevent this disease include quitting smoking, exercising regularly, eating a healthy diet and maintaining a healthy weight.
