The cause of varicose veins is multifactorial. The following factors may contribute to their development.
- Gender- females are affected four times as often as men
- Age- development is progressive and tends to advance as we get older
- Heredity- this contributes greatly to the development of vein disorders
- Pregnancy- hormonal factors and increased circulating blood volume predispose toward development of varicosities. After delivery, the veins may regress.
- Occupation - prolonged standing and sitting can exacerbate any underlying tendency toward the development of varicose veins
- Lifestyle- obesity and a sedentary lifestyle have been implicated as significant contributing factors, as well as chronic constipation, high heels, binding clothing, heat, birth control pills or hormone replacement therapy
