What Causes Spider Veins?

While there are several underlying reasons and causes of spider veins, the consensus seems to agree on pressure. Pressure from increased weight gain, pressure on the legs and thighs from fatty tissue or fluid build-up, pressure from plastic surgery (as in breast augmentation), or pressure related to being on your feet all the time (as in work-related).

How does pressure play a role?

Spider veins are considered the result of leaking through the vein walls which then coagulates leaving reddish, fine lines; poorly functioning or blocked valves which causes circulation “mis-direction” or blockage and swelling; or protrusion up and to the surface of the skin increasing visibility.

Presssure is considered a cause for many of these symptoms and ailments. Why? The first is the most obvious. Standing on our feet all day because of work or home chores can increase blood pressure to lower extremities – our legs, thighs, calves, etc. – pushing capillaries closer to the surface making them more visible. It can also increase pressure applied to the vein walls and structure increasing the propbability that leaking or malfunction can occur.

Similarly, weight gain – especially if related to cellulite build-up, can squeeze tissue and surrounding muscle making capillaries more visible and prominent while adding the risk of damage. It is also considered a valid cause that natural aging and associated free-radical damage complicates appearance. Many experts believe that free-radical damage caused by oxidization damages organs and tissue. UV rays, smoking, and alcohol use accelerate free-radical damage causing cell membranes to become weak. This can lead to leaking and poor circulation – giving rise to spider veins on the nose, cheeks, and underneath the eyes, as well.
