What Causes Spider Veins?

Spider veins are small, red or purple veins that can appear on your legs. They are called spider veins because they resemble spider webs. Spider veins are, for the most part, considered a cosmetic issue and can be easily removed through a minimally invasive procedure called sclerotherapy.

However, if you notice dense clusters of spider veins in your lower legs or ankles, it is important to seek medical attention. These dense clusters may indicate a more serious case of venous insufficiency. Venous insufficiency occurs when the valves inside the legs do not allow blood to travel back to the heart. This causes the blood to pool inside the vein, which results in spider or varicose veins.

Common causes of spider veins

Spider veins are extremely common and often the result of poor circulation. They may also appear as a result of the following causes:

  • Increased pressure in the veins (resulting from standing or sitting for long periods of time)
  • Decreased leg circulation
  • Hormonal changes due to puberty, pregnancy or menopause
  • Wearing a girdle or clothing that is too tight
  • Aging
  • A family history of blood clots
  • Obesity

Common symptoms of spider veins

Spider veins usually do not cause any symptoms. In some cases, however, they may cause discomfort, like stinging or burning sensations.

If you have symptoms of or are concerned about the appearance of spider veins, there are effective treatment options available. Sclerotherapy is the most common minimally invasive procedure. In this procedure, a skilled sclerotherapist injects a solution into the vein or veins that causes them to scar and close. When this happens, your blood is rerouted through healthy veins. In a few weeks, you will notice the treated spider veins have faded.
