Overview of Peripheral Artery Disease

Peripheral artery disease (PAD) is a common condition in which there is a narrowing or blockage of the arteries that supply blood to the legs and feet. This happens when the buildup of fatty deposits or plaque in the arteries, known as atherosclerosis, causes the arteries to become narrow and stiff. As a result, there is a reduced blood flow to the legs and feet, leading to symptoms such as leg pain, cramping, and weakness.

PAD is more common in older adults and is often related to other health conditions, such as diabetes, high blood pressure, and high cholesterol. People who smoke or have a family history of PAD are also at higher risk.

If left untreated, PAD can lead to serious complications, including non-healing wounds or infections, gangrene, and even amputation. It is important to diagnose and treat PAD early to prevent these complications.

Treatment for PAD may include lifestyle changes, such as quitting smoking, regular exercise, and healthy eating, as well as medications to manage underlying conditions such as high blood pressure and cholesterol. In some cases, procedures such as angioplasty or bypass surgery may be necessary to restore blood flow to the affected areas.
