Peripheral Arterial Disease
Peripheral Arterial Disease (PAD) is a common circulation problem in which the arteries that carry blood to the legs or arms become narrowed or clogged.
This interferes with the normal flow of blood, sometimes causing pain, but often causing no symptoms at all. The most common cause of PAD (also known as Peripheral Vascular Disease, or PVD) is atherosclerosis, often called "hardening of the arteries." Atherosclerosis is a gradual process in which cholesterol and scar tissue build up, forming a substance called "plaque" that clogs the blood vessels. In some cases, PAD may be caused by blood clots that lodge in the arteries and restrict blood flow.
If these symptoms are left untreated, this insufficient blood flow will lead to limb amputation in some patients. In atherosclerosis, the blood flow channel narrows from the buildup of plaque, preventing blood from passing through as needed, restricting oxygen and other nutrients from getting to normal tissue.
The arteries also become rigid and less elastic, and are less able to react to tissue demands for changes in blood flow. Many of the risk factors (high cholesterol, high blood pressure, smoking and diabetes) may also damage the blood vessel wall, making the blood vessel prone to diffuse plaque deposits.
Your Lifestyle with PAD
Once you have been diagnosed with PAD, there are several treatment options you and your doctors at Arteries & Veins can discuss and explore. Often PAD can be treated with lifestyle modification. Smoking cessation and a structured exercise program are often all that is needed to alleviate symptoms and prevent further progression of the disease.
