A common condition in which narrowed arteries reduce blood flow to the arms or legs.

Peripheral artery disease (PAD) is usually a sign of a buildup of fatty deposits in the arteries, a condition called atherosclerosis. Risk factors for PAD include aging, high blood pressure, high cholesterol, diabetes and smoking.

Symptoms may include leg pain, especially when walking. Some people have muscle cramps. Other symptoms are leg numbness and weakness.

Lifestyle changes help treat peripheral artery disease. Eat healthy foods, get regular exercise, stay active, and do not smoke or use tobacco. Some people with PAD need medicines or surgery to improve blood flow.
