These veins have experienced the breakdown in the return pump valve, which in turn allows the blood to stay in these veins resulting in their dilation. Once a vein becomes dilated, it is no longer functioning optimally for the benefit for the body’s circulatory system.
Why varicose veins do occurs?
In some instances, the absence or weakness of valves in the veins may cause poor venous circulation (blood flow in the veins) and lead to varicose veins. Valves inside veins normally act to ensure that blood in the veins does not flow in a backward direction (retrograde) away from the large (deep) veins and the heart.
- Varicose veins can happen to anybody. It is more likely to happen to you if your parents or relatives had them.
- Standing per se does not cause varicose veins. It hastens the deterioration of malfunctioning valves and thus the development of varicose veins.
- Pregnancy again does not cause varicose veins. Varicose veins occur in pregnant women with already deteriorating valves. So pregnancy is not a cause but a contributing factor.
- A varicose vein Gene presence does not necessarily produces varicosities as environmental factors also play role in gene expression. Controlling these factors one can delay unpleasant appearance of varicose veins.
In women, symptoms may be worse during certain parts of the menstrual cycle or during pregnancy. Less common is swelling, ulcers and a darkening of the skin, especially in the ankle region. Occasionally, varicose veins can form a painful blood clot with inflammation of the vein, a condition called thrombophlebitis.
