Peripheral artery disease and venous issues linked to leg discomfort

Symptoms such as heavy legs, pain while walking, and swelling can indicate serious underlying medical conditions. Peripheral artery disease (PAD) occurs when arteries supplying blood to the legs narrow due to cholesterol buildup and other substances. While the classic symptom is intermittent claudication—cramping or pain in the calf, thigh, or buttock that subsides with rest—many individuals, particularly women, may not experience this typical pattern.

PAD is a significant indicator of systemic atherosclerosis, which increases the risk of heart attack, stroke, and cardiovascular death. Diagnosis can involve comparing blood pressure at the ankle to that at the arm.

Additionally, heavy or swollen legs can be caused by venous diseases. When the valves in the veins fail to function correctly, blood can stagnate, leading to swelling, heaviness, or visible varicose veins. These issues are more common in sedentary individuals, those who are overweight, or following pregnancy. Medical professionals suggest consulting a vascular surgeon for diagnosis and recommend lifestyle adjustments, such as elevating the legs above heart level, to manage symptoms.
