Risk Factors for Spider Veins

Risk Factors for Spider Veins

Research has shown that there are several factors that can make you more susceptible to spider veins. There are some that you can manage, while others are completely out of your control. Genetics plays a role in spider veins. If someone in your family suffers from spider veins, then you are more likely to develop them as well. Excess weight, previous injuries to the area, and external stress also contribute to spider veins. Although spider veins can develop almost anywhere on the body (face, shoulders, back, etc.) they are most commonly found on the legs. It is not uncommon for spider veins to develop alongside varicose veins.

The causes of spider and varicose veins are very similar. They result from a lack of blood flow. Spider veins, while not as serious as varicose veins, can be a symptom of a more pressing medical condition. Spider veins often have no other symptoms. When a vein becomes weak or damaged, it can no longer push the blood back to the heart. This is when varicose or spider veins are formed. These conditions are particularly common in the legs since the blood valves have to work against the force of gravity. The backflow or pooling of the blood causes venous reflux in the veins just below the surface of the skin. These smaller veins take on more blood than they were designed to handle and dilate to over twice their original diameter. This swelling makes them more visible through the skin.


Sclerotherapy Treatment for Spider Veins

Sclerotherapy is the name of a treatment that uses an injectable solution on undesirable veins causing them to close off from the surrounding vessels. Sclerotherapy works best with smaller spider veins that are close to the surface however, it can be employed to treat deeper veins with the assistance of ultrasound guidance.
