Peripheral arterial disease (PAD) is narrowing or blockage of arteries that causes poor blood flow to your arms and legs. PAD is most common in the legs.
The most common cause of PAD is the buildup of plaque on the inside of arteries. Over time, plaque builds up in the walls of the arteries, including those that supply blood to your legs. If you have PAD, you're likely to have plaque in other arteries in your body. This raises your risk of a heart attack and stroke.
Peripheral arterial disease is also called peripheral vascular disease.
Many people who have PAD don't have symptoms.
If you have symptoms, they may include a tight, aching, or squeezing pain in your calf, thigh, or buttock. This pain is called intermittent claudication. It usually happens after you have walked a certain distance. The pain goes away if you stop walking. As PAD gets worse, you may have pain in your foot or toe when you aren't walking.
Other symptoms may include weak or tired legs. You might have trouble walking or balancing.
If PAD gets worse, you may have other symptoms caused by poor blood flow to your legs and feet. These symptoms aren't common. They may include cold or numb feet or toes, sores that are slow to heal, or leg or foot pain when you're at rest.
Treatment for PAD focuses on relieving symptoms and lowering your risk of heart attack and stroke. Making healthy lifestyle changes can help you lower this risk.
You may need medicines to help lower your risk of heart attack and stroke. These include medicine to prevent blood clots, improve cholesterol, or lower blood pressure.
People who have severe PAD may have bypass surgery or other procedures (such as angioplasty) to restore proper blood flow to the legs.
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 call line 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.
