Spider veins are small veins visible through the skin. These veins can be blue, red or purple in color and are typically seen on a person’s face and legs.
For some people, the development of spider veins is hereditary. Others develop the veins by working in professions that require a lot of standing, such as teaching, nursing or waitressing. Health problems such as obesity or a history of blood clots could also cause spider veins to develop. In some cases, spider veins might also develop due to birth control pills, tumors, constipation, hormonal changes during puberty, pregnancy or menopause, and postmenopausal hormone therapy
