What is Peripheral Artery Disease?

Peripheral artery disease (PAD) is a condition that occurs when the arteries that carry blood to the legs and feet become narrowed or blocked, reducing the flow of oxygen-rich blood to these areas. PAD is often caused by the buildup of plaque in the arteries, which can be a result of high cholesterol, high blood pressure, smoking, or other factors.

Symptoms of PAD may include leg pain or cramping, particularly when walking or climbing stairs, numbness or weakness in the legs, and coldness in the lower legs and feet. PAD can increase the risk of serious health problems, such as heart attack, stroke, and amputation.

PAD is typically diagnosed through a physical exam, a review of medical history, and certain tests, such as an ankle-brachial index (ABI) test or a doppler ultrasound. Treatment for PAD may include lifestyle changes, such as quitting smoking, eating a healthy diet, and getting regular physical activity, as well as medications, such as aspirin or blood thinners, and procedures, such as angioplasty or stenting.

It is important to seek medical attention if you have symptoms of PAD or have risk factors for the condition, as early diagnosis and treatment can help to reduce the risk of serious complications.
