Left untreated, the ailment can pose serious dangers such as heart attack and stroke. Get a leg up on the symptoms and your risk factors.

Marked by decreased blood flow in the legs due to narrowing — or even complete blockage — of arteries, peripheral artery disease (PAD) affects more than 8 million people in the United States.

Such blockage is caused by a buildup of plaque and fatty deposits, which puts patients (even asymptomatic ones) at a heightened risk for heart attack and stroke.

Fortunately, the hazards can be reduced with medical therapy.

And a better understanding of PAD, which also can affect arteries of the abdomen or pelvis, helps patients ask the right questions, make informed choices and get more actively engaged in their own health and wellness.

With September serving as PAD Awareness Month, here are some key things to know.

Your lifestyle and health history matter. Over time, various factors cause the vein walls to become rigid and narrow. According to the American Heart Association, risk factors that contribute to PAD include:

  • Diabetes

  • Personal or family history of PAD, cardiovascular disease or stroke

  • Cigarette smoking

  • High blood cholesterol

  • Chronic high blood pressure

  • Obesity

  • Physical inactivity

  • Age over 65 (or age over 50, plus any of the risk factors listed above)

Look for the warning signs. Understanding the signs and symptoms can help identify patients who should be tested for PAD. Early diagnosis allows timely treatment and can help avoid complications like infection or even amputation.

Common symptoms include:

  • A change in the skin color of your legs or feet

  • A wound on the foot that does not heal

  • Loss of hair on feet or legs

  • Crampy leg pain during walking that goes away with rest

  • Pain in your legs or feet that wakes you up at night

  • Absent or decreased pulses in the legs or feet

If you’re experiencing any of these above, see a doctor.

You can get tested (and treated). PAD is diagnosed with a noninvasive test — an ankle brachial pressure index, which measures the difference between the systolic blood pressure in your arms and ankles — that can help determine whether symptoms are a result of PAD or another condition.

If you’re diagnosed with PAD, continue to see your health care provider regularly and ask what treatment is best for you. Many patients are successfully treated with a supervised exercise program or medication; severe cases may require a surgical procedure.  

Also, be sure to consider the following:

  • Check your legs and feet regularly for wounds, sores or change in skin color

  • Wear properly fitted shoes and avoid walking barefoot

  • If you smoke, ask about resources to help you stop

  • Improve your diet with foods low in fat and cholesterol

  • Manage high blood pressure, cholesterol, weight and diabetes

  • Take your medications as prescribed
