What symptom may indicate peripheral artery disease?

Coldness in the lower leg can indicate peripheral artery disease (PAD) because this condition is characterized by narrowed arteries that reduce blood flow to the limbs, particularly the legs. When blood flow is compromised, the affected areas can become cold to the touch due to insufficient warmth and oxygen supplied by the blood. In addition to coldness, patients may also experience other symptoms, such as leg pain during physical activity (claudication), numbness, or changes in the color of the skin.

The distinction of coldness in the leg as a symptom is important in recognizing PAD, as it reflects the underlying issue of blood flow restriction and the body's response to reduced circulation. Understanding these symptoms is crucial for early diagnosis and management of cardiovascular health.
