Overview
Varicose veins are more common in women than in men, and are linked with heredity.[1] Other related factors are pregnancy, obesity, menopause, aging, prolonged standing, leg injury and abdominal straining. Varicose veins are bulging veins that are larger than spider veins, typically 3 mm or more in diameter.[2] Varicose veins are distinguished from reticular veins (blue veins) and telangiectasias (spider veins) which also involve valvular insufficiency,[3] by the size and location of the veins.
