Over 80 million people have problems with varicose veins and spider veins. These conditions are often hereditary. Hormonal factors such as puberty, pregnancy and menopause, and the use of birth control pills containing estrogen or progesterone also affect veins. Age, leg injury, obesity, lack of exercise, weight fluctuation, constriction, and prolonged sitting and standing can be additional contributing factors.
