Overview
Peripheral artery disease is narrowing of the arteries that carry blood to the legs, usually from the same cholesterol build-up that affects the heart. Its classic sign is cramping leg pain on walking that eases with rest. It signals widespread artery disease and a higher risk of heart attack and stroke, so it is an important warning. In severe cases, poor blood flow can threaten the limb. Stopping smoking, exercise and treating risk factors greatly help.
Symptoms
- Cramping pain in the calves or thighs on walking, eased by rest
- Cold, pale feet and weak pulses
- Numbness or weakness in the legs
- Slow-healing sores on the feet or toes
- Hair loss and shiny skin on the lower legs
When to see a doctor
See a doctor for cramping leg pain on walking, or cold, pale legs, and urgently for a foot wound that will not heal or a suddenly cold, painful leg.
Emergency — call 108 or go to the nearest hospital
- A suddenly cold, pale, painful or numb leg or foot — a possible blocked artery, seek emergency care immediately
Causes
Cholesterol build-up narrowing the leg arteries, driven by smoking, diabetes, high blood pressure, high cholesterol and age.
