Overview
Peripheral arterial disease (PAD) occurs when the blood vessels (arteries) that supply blood to the legs, belly, pelvis, arms, or neck get narrow or blocked. This reduces blood flow to that area. The legs are affected most often.
PAD is often caused by fatty buildup (plaque) in the arteries. This buildup is also called "hardening" of the arteries. Your risk of PAD increases if you smoke or have diabetes, high cholesterol, high blood pressure, or a family history of PAD.
Many people don't have symptoms. If you do have symptoms, you may have weak or tired legs, difficulty walking or balancing, or pain. If you have pain, you might feel a tight, aching, or squeezing pain in the calf, foot, thigh, or buttock that occurs during exercise. The pain usually gets worse during exercise and goes away when you rest. If PAD gets worse, you may have symptoms of poor blood flow, such as leg pain when you rest.
Medicine and a specialized exercise program may help relieve symptoms. Medicine and a heart-healthy lifestyle can help slow the progress of the disease and lower your risk of heart attack and stroke. If PAD is severe, a procedure or surgery may be done to improve blood flow.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
