Spider veins are similar to varicose veins, but smaller and closer to the surface of the skin. They are often red or blue in color. They often resemble a tree branch or spider web. Spider veins can be found on both the legs and the face.
Causes of Spider Veins
Although the precise cause of spider veins is unknown, there are several factors that contribute to their development.
- Heredity – Being born with weak vein valves, is the most common factor.
- Homones – The hormonal changes that occur during puberty, pregnancy, and menopause, as well as taking estrogen, progesterone, and birth control pills can cause a woman to develop spider veins.
- Pregnancy – The circulatory system changes during pregnancy, allowing blood to flow more freely in the body, but decreasing flow from the legs to the pelvis. This change can result in enlarged veins in the legs, which may or may not improve on their own once the pregnancy is over.
- Leg Injury
- Prolonged Standing or Sitting
- Sun Exposure
Symptoms of Spider Veins
In most cases there are no symptoms of spider veins. The tiny veins appear on the surface of the skin because blood is restricted from flowing to the affected areas properly.
Symptoms often occur during times of prolonged standing or sitting.
Less common symptoms may include:
- tingling, throbbing, pressure in the limbs
- tiredness in the limbs
- cramping or aching due to decreased blood flow in the areas which the spider veins appear
