Cause
The arteries carry blood from the heart to all of your body tissues. Veins return blood from the rest of your body to your heart, so the blood can be recirculated. To restore blood to your heart, the blood vessels in your leg should work against gravity.
Muscle contraction in your lower leg acts as a pump, and the walls of the elastic vessels help the blood return to your heart. The small valve in your blood vessels opens as blood flows toward your heart and closes the bloodstream to keep it from flowing backwards.
The causes of varicose veins may include:
Age. As you age, your blood vessels may lose elasticity, causing it to stretch. The valves in your blood vessels may become weak, allowing blood that should move toward your heart to flow backwards.
The blood vessels in your blood vessels, and your blood vessels become enlarged and become varicose veins. The veins look blue because they contain deoxygenated blood, which is in the process of being circulated through the lungs. Pregnancy. Some pregnant women develop varicose veins. Pregnancy increases the volume of blood in your body, but lowers blood flow from the legs to your pelvis. These circulatory changes are designed to support fetal growth, but can produce unfavorable side effects - enlarged blood vessels in your legs.
Varicose veins may appear for the first time or may worsen during late pregnancy, when your uterus puts more pressure on the blood vessels in your legs. Your hormonal changes during pregnancy may also play a role. Varicose veins that develop during pregnancy generally improve without medical treatment three to 12 months after delivery.
