CAUSES OF VENOUS INSUFFICIENCY
What causes venous insufficiency?
Varicose veins is a very common condition. It is estimated that 30% to 50% of the population across the globe suffer from some form of venous disorder.
Heredity is a major contributing factor for varicose and spider veins.
Women are more likely than men to suffer from venous insufficiency. Varicose veins are about 3 times more common in females than males.
In women, pregnancy is one of the most common factors that contribute to the occurrence of varicose veins. It is common for varicose veins to become more prominent during pregnancy and worsen with successive pregnancies.
Hormonal factors seen during puberty, pregnancy, menopause and consumption of birth control pills affect the disease.
Aging causes wear and tear on the valves in your veins that help regulate blood flow. Eventually, that wearing and aging causes the valves to lose their elasticity allow some blood to flow back in a reverse direction instead of flowing up to your heart.
Additional factors, while not directly the cause of varicose veins, may speed up the development of this disease and make the veins worse, include prolonged standing, obesity and physical trauma.
