THE CAUSE OF SPIDER VEINS

Spider veins are clusters of small surface veins that are typically red, blue or purple and have developed from weakened or damaged valves in the tiny vessels. Spider veins are much smaller than varicose veins but do not often cause pain or symptoms. Below are some causes of spider veins and ways of prevention:

• Genetics

There is a strong familial component for developing spider veins. Often times, patients will report multiple family members with pesky spider veins.

• Pregnancy

Hormonal changes and abdominal pressure during pregnancy can cause spider veins to form or become more prominent.

• Excessive Standing or Sitting

Long periods of standing or sitting can increase pressure in the veins, causing them to dilate and damage the valves, leading to prominent veins on the skin. Try to take short breaks when sitting or standing for long periods of time or do a brief walk. Compression stockings may also help reduce some of the pressure on the veins when standing or sitting for extended periods.

• Sedentary lifestyle and increased BMI (Body Mass Index)

Exercise and maintaining a healthy weight can help decrease the risk of spider veins.

• Trauma or injury

Some people will notice spider vein formation after a focal trauma to their leg.
