Atherosclerosis, or the narrowing of blood vessels, is an equal opportunity disorder. While atherosclerosis in the coronary arteries leads to the number one cause of death in Western civilization, blood vessels throughout the rest of the body can get clogged, too. The problem, known as peripheral artery disease, or PAD, afflicts up to 12 million Americans, though only about half develop symptoms.
PAD can occur in the arms and other parts of the body but most often strikes below the belt. As blood flow to leg muscles slows down, pain and cramping can result in the calves, thighs, or hips while walking. The discomfort fades if you stop to rest. Because the pain comes and goes, it's known as intermittent claudication.
Many people who develop PAD symptoms never mention them to doctors, figuring a little pain now and then is part of aging. But over time, lack of adequate blood flow to the lower limbs can lead to some serious consequences. Poor circulation to the lower extremities can lead to nasty sores, gangrene, and even an amputated foot or two.
Here's why you should really care: People with diabetes are two to three times more likely than people who don't have the disease to develop PAD. In fact, as a diabetes patient, once you reach age 50, your odds are about one in three. Furthermore, when compared to other patients with PAD, people with diabetes are 10 to 30 times more likely to have a foot amputated.
And believe it or not, that isn't the scariest part. Doctors have come to think of PAD as a red flag -- a warning that a patient is a heart attack or stroke waiting to happen. One study found that 70 percent of people who have PAD also have severe blockages in their coronary arteries. Another determined that intermittent claudication shortens lifespan by about 10 years.
There is much more to the PAD story, but because it is exacerbated by nerve damage -- and because foot problems are a major part of managing diabetes.
Diabetes can affect a diabetic's heart health in several ways. Keeping your heart as healthy as possible -- while controlling your blood sugar -- is essential. Talk with your doctor about your potential risks.
