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 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.
How can you care for yourself at home?
- Try to quit or cut back on using tobacco and other nicotine products. This includes smoking and vaping. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good. Try to avoid secondhand smoke too.
- Take your medicines exactly as prescribed. Call your doctor if you think you are having a problem with your medicine.
- If you take a medicine to prevent blood clots, be sure to get instructions about how to take your medicine safely. This medicine can cause serious bleeding problems.
- If you have symptoms when you exercise, ask your doctor if a specialized exercise program is right for you. This program may help relieve your symptoms and help you walk farther without pain.
- Eat heart-healthy foods. These include vegetables, fruits, nuts, beans, lean meat, fish, and whole grains. Limit sodium, sugar, and alcohol.
- Be active. Try to get at least 30 minutes of physical activity on most days of the week. Talk to your doctor about what type and level of exercise is safe for you.
- Stay at a weight that's healthy for you. Talk to your doctor if you need help losing weight.
- Try to get 7 to 9 hours of sleep each night.
- Manage other health problems such as high blood pressure, high cholesterol, and diabetes. If you think you may have a problem with alcohol or drug use, talk to your doctor.
- Avoid infections such as COVID-19, colds, and the flu. Get the flu vaccine every year. Get a pneumococcal vaccine. If you have had one before, ask your doctor whether you need another dose. Stay up to date on your COVID-19 vaccines.
- Watch for new or worse symptoms. Know when to call your doctor or get help right away.
- Take good care of your feet.
- Wash your feet every day. Use warm (not hot) water.
- Check for blisters, cuts, cracks, or sores. If you have a foot problem, see your doctor. Don't try to treat a foot problem at home.
- Use moisturizing skin cream to keep your feet soft.
- Wear shoes and socks that fit well.
- Keep your nails trimmed.
