Loss of hair on the lower extremities in males can stem from a variety of factors. Reduced blood flow to the legs, often due to peripheral artery disease, is a common cause. This restricted circulation deprives hair follicles of essential nutrients and oxygen, inhibiting hair growth. For instance, an individual with long-standing diabetes may experience diminished leg hair as a consequence of vascular complications.
The presence or absence of leg hair can serve as an indicator of underlying health conditions. Observing changes in hair distribution can prompt individuals and healthcare providers to investigate potential circulatory issues or other systemic diseases. Historically, physical examinations have included assessments of hair patterns as part of a broader evaluation of a patient’s overall health.
