Introduction to Peripheral Artery Disease

Peripheral artery disease (PAD) is a condition that affects the blood vessels carrying oxygenated blood to various parts of the body, including the legs, arms, stomach, and head. It occurs when there is a narrowing or blockage of these blood vessels due to atherosclerosis, which is the buildup of plaque inside the arteries.

Recognizing the symptoms of PAD is crucial because early intervention can prevent complications and improve overall quality of life. When left untreated, PAD can lead to serious health issues such as tissue death (gangrene) and even amputation.
