Risk factors discussion:
No one knows the exact cause of spider and varicose veins, but there
are several factors that cause a person to be more likely to develop them.
Heredity, or being born with weak vein valves, is the greatest factor.
Hormones also play a role. The hormonal changes that occur during puberty,
pregnancy, and menopause, as well as taking estrogen, progesterone, and
birth control pills can cause a woman to develop varicose veins or spider
veins. During pregnancy, besides the increases in hormone levels, there
also is a great increase in the volume of blood in the body that can cause
veins to enlarge. The enlarged uterus also puts more pressure on the
veins. (Within 3 months after delivery, varicose veins usually improve.
However, more abnormal veins are likely to develop and remain after
Other factors that weaken vein valves and that may cause varicose or
spider veins include aging, obesity, leg injury, and prolonged standing,
such as for long hours on the job. Spider veins on the cheeks or nose of a
fair-skinned person may occur from sun exposure.

About risk factors:
Risk factors for Varicose veins are factors that do not seem
to be a direct cause of the disease,
but seem to be associated in some way.
Having a risk factor for Varicose veins
makes the chances
of getting a condition higher but does
not always lead to Varicose veins.
Also, the absence of any risk factors
or having a protective factor does not necessarily
guard you against getting Varicose veins.
