What causes varicose and spider veins?
The causes of varicose and spider veins are not entirely understood. 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. They are mainly located in perforating veins and some deep veins.

In other cases, weaknesses in the vein walls may cause pooling of the blood. The walls of the blood vessels can become weaker and less competent than normal, causing the volume of blood in the veins to increase, thus leading to varicose veins.
Less commonly, varicose veins are caused by such diseases as:
- phlebitis (inflammation of the veins),
- blood clots or any obstruction to blood flow in the veins, or
- congenital abnormalities of the veins.
Venous disease (disease of the veins) is generally progressive and may not be prevented entirely. However, in some cases, wearing support hosiery, maintaining a normal weight, and regular exercise may be beneficial.Continue Reading
