Factors That Play A Major Role In The Development of Varicose Veins

Varicose veins are enlarged veins that become gnarled, which most often affect the feet and/or legs although any vein can be affected. All veins have elastic walls, which help push blood back to the heart. They also have tiny valves, which open to allow the blood to flow through them and towards the heart. The valves then close, stopping the blood flow, which prevents the blood from flowing in a backwards direction. Feet and legs are more susceptible to varicose veins because their veins must function against the force of gravity. This is done as the lower leg muscles contract to push the blood through the veins. The entire process of normal blood circulation requires all parts of the circulatory system to be functioning properly. Because of certain factors that can occur, these can play a major role in the development of varicose veins.

Pregnancy

One such factor that can lead to varicose veins is pregnancy. Due to the need of the body to provide support to the foetus for proper growth, changes in the circulatory system must occur. These changes include increasing the amount of blood in the body, but at the same time decreasing the blood flow from the legs to the pelvic area. Although this is vital for healthy foetal growth, it can also cause varicose veins. This is especially true during the later stages of pregnancy as the uterus enlarges causing additional pressure on the veins of the feet and legs. Hormonal changes during pregnancy can also play a role in the development of varicose veins.

Age

Another common factor of varicose veins is age. Due to the natural aging process, veins lose their elasticity, which can cause them to become over-stretched. The vein's values can also become weak, causing blood flow to backup in the veins. When this occurs, the blood forms a pool, causing veins to enlarge and develop into varicose veins. Varicose veins contain pooled blood that has not been oxygenated, causing the bluish appearance of veins.

Sex

Sex is also a factor for the development of varicose veins. Women have a much greater risk of varicose veins due to the many hormonal changes that occur during pre-menstruation, pregnancy and menopause. Those who take birth control pills or hormone replacement therapy are at greater risk of varicose vein development as higher levels of female hormones can cause the walls of veins to weaken.

Additional Factors That Can Increase The Risk Of Varicose Veins

Other factors that can increase the risks of developing varicose veins include obesity, as the extra weight can add pressure on the veins, family history and sitting or standing for extended periods. When the same positions are maintained for long periods, poor blood flow can result.
