Spider veins are blood vessels located just beneath the skin surface that grow larger and appear red or blue when they weaken and become clogged. They most often appear in "sunburst" patterns on the face and legs, but also can affect other areas of the body. Varicose veins are similar to spider veins, but they are larger, darker in color and tend to bulge.

Spider and varicose veins appear in both sexes, but are more common in women. They may be caused by a number of factors including fluctuations in hormones, wearing high-heeled shoes, aging, sun exposure and obesity. Occupation that requires long periods of sitting or standing can also contribute to the development of these vein conditions.

In addition to the cosmetic concerns of spider and varicose veins, the conditions may cause dull, aching sensations after prolonged standing. In rare cases, they may be associated with more serious health consequences, such as fatigue, night cramps and leg swelling.

"Due to predisposed conditions, varicose and spider veins may be inevitable for some people. However, there are preventative measures and medical techniques available to diminish the appearance and pain associated with these vein conditions," Dr. Robert Weiss, vice president of the American Society for Dermatologic Surgery (ASDS), said in one of the society's publications.

Dr. Weiss recommends that patients exercise to maintain adequate circulation in their legs. This ultimately helps reduce pressure and blood pooling. Weight loss also can lessen pressure on legs and ankles. In addition, Dr. Weiss recommends that patients suffering from spider or varicose veins speak to their physicians to learn about the treatment options available, such as laser therapy or injections.

These recommendations were provided in the winter 2006 issue of The Skin Source, an online publication of the American Society for Dermatologic Surgery.
