Why Do My Legs Feel Heavy When I Walk?

Heavy legs during walking typically indicate poor blood circulation or muscle fatigue. This sensation occurs when blood pools in your lower extremities due to weakened valves in your veins, a condition affecting up to 40% of adults over 40. Dehydration, prolonged sitting, or underlying conditions like peripheral artery disease can also cause this symptom. Other contributing factors include medication side effects, electrolyte imbalances, or simply muscle overuse from increased activity levels. The feeling often worsens throughout the day as gravity pulls blood downward. If heavy legs persist for more than a few weeks or occur with swelling, pain, or skin changes, consult a healthcare provider to rule out serious vascular conditions.
