What are Spider Veins?
Spider veins are thin vessels, capillaries, connected with the larger venous system. They are small groups of tiny blood vessels located just under the surface of the skin, often resembling a branch or a web in shape. Similar to varicose veins, they are caused by a condition known as venous reflux.
Spider veins are the mildest manifestation of venous insufficiency, smaller in size to varicose veins. They can appear isolated or they may be associated with larger, underlying varicose veins. While spider veins can cover large areas of the skin’s surface, they rarely cause physical symptoms.
Causes of Spider Veins
- Age: As you get older, the valves in your veins may weaken and fail to function properly.
- Heredity: Those individuals who have family members with a history of vein problems tend to see a higher occurrence of vein issues themselves.
- Hormonal changes: Hormonal changes from puberty, pregnancy and menopause may contribute to the onset of varicose or spider veins.
- Sun damage: Prolonged sun exposure may cause the onset of spider veins , particularly in the facial region.
