What causes varicose veins?


  • Hereditary- this runs in the family history unfortunately. The leg veins inherit the tendency for the venous systems pressure to increase over time.
  • Prolonged standing- Standing for prolonged periods causes increase pressure in the venous system causing the valves that assist with the return of the blood to the heart to collapse leading to pooling of blood in the veins.
  • Pregnancy-There is an increase in blood volume during pregnancy, leading to increase pressure demands on the venous backflow system.
