Varicose Veins Causes  

The function of your veins is to deliver blood to your heart from the outer parts of your body. To achieve this crucial task, they have a multitude of valves that open in one direction, forcing the oxygen-poor blood to flow one way into the heart. When the walls of the veins lose their elasticity and their tone, the veins tend to dilate, causing a stagnation of blood (or blood stasis) in the dilated area. Over time, this overload of blood weakens the valves. They then let blood leak in the tissues causing swelling of the veins in the legs and feet. Weak muscle tone in the legs is another factor that may hinder blood flow in the veins.  

People at risk:  

Sex - 80% of varicose veins cases are from women. The problem can be due to hormonal changes associated with pregnancy, premenstrual period and menopause, which also contribute to weaken vein walls. Birth control pills and hormone replacement may also play a role in the occurrence of varicose veins in women. 

Age - age plays a major role in the health of your veins. As you get older, your veins start losing their elasticity and their ability to contract. As the valves tend to diverge, their edges are no longer able to merge to prevent blood reflux, which leads eventually to varicose veins. This degeneration can begin from your thirties.  

Heredity – heredityis primarily responsible for the occurrence of varicose veins. Experts from Harvard University confirm that more than 50% of people who suffer from varicose veins have inherited from their parents. That is, if you have members in your family who have varicose veins, you are at greater risk to have it. 

Pregnancy - Pregnant women are at greater risk of developing varicose veins because of secretion of certain hormones during the pregnancy that tend to weaken the tone of their venous walls. In addition, the weight of the baby can affect the health of the veins. However, varicose veins which are purely related to pregnancy often resolve by themselves during the first three months following the childbirth. 

Certain Professions - people who work standing for a long period of time such as nurses and servers are particularly affected by the problems of vein problems including varicose.
