For more than an estimated 80 million Americans, vein problems affect every day life. Spider veins and varicose veins can not only be detrimental to physical appearance, but when left untreated, can also cause more serious health conditions. Vein conditions impact men and women alike, and can stem from a variety of factors including genetic predisposition, prolonged standing from work or lifestyle, increased height, congenital valvular dysfunction, obesity, and even multiple pregnancies. These factors all can contribute to the development of spider and varicose veins.
