When Linda Molnar originally went to doctors about an acute pain in her legs, she was assured that it was due to a back injury she had suffered some time ago. However, after another three years, a specialist finally discovered the real reason that she was becoming unable to even walk short distances without aches – peripheral artery disease, according to The Wall Street Journal.

This condition, which affects up to 12 million Americans, is caused by poor circulation in the legs that is a result of fatty deposits building up in the arteries.

"Peripheral artery disease is the most common, deadly and costly cardiovascular disease that the public hasn't heard of," Alan T. Hirsch, a professor at the University of Minnesota Medical School's cardiovascular division, told the news provider.

Many, like Molnar, are unaware that they even have the condition.

The news source reports that maintaining a proper diet and regular exercise can reduce the risk of peripheral artery disease significantly.

LiveStrong.com reports that looking for rich sources of omega-3 fatty acids, cod liver oil or calcium can help cure clogged arteries. Drinking green tea and eating garlic may also help.
