1) The aging process tends to thicken, stiffen and narrow arteries. This is known as arteriosclerosis

2) Plaque and cholesterol builds up within large and medium sized arteries (atherosclerosis)

3) Narrowed blood vessels that lead to the brain can result in carotid artery disease. This condition can lead to a stroke.
4) An aneurysm is the progressive weakening of a blood vessel wall. If not diagnosed and treated, an abdominal aortic aneurysm (AAA) can rupture. AAAs account for approximately 15,000 deaths in the United States annually.

5) Narrowed arteries in the legs, known as peripheral arterial disease (PAD), can lead to sores, pain when walking or even amputation.

Vascular surgeons can monitor these conditions. They will often recommend diet modifications, exercise, or prescription medications for vascular conditions. If necessary, vascular surgeons can place stents and perform angioplasties and bypass surgery.
