There are a number of factors which lead to Vein
Heredity - The risk of vein reflux disease
is most commonly attributed to the hereditary traits
of one's family.
Gender - Women have a higher incidence of
vein reflux disease due, in part, to the female hormones
affecting the structure of the vein walls.
Pregnancy - Pregnancy can cause an increase in blood pressure,
which results in more pressure and stress on the walls of the vein.
Age - As we age, our tissues lose elasticity,
resulting in weakened vein walls and valves.
There are additional factors which do not
cause vein reflux, but will expedite the development
and severity of the disease:
Obesity - A substantial increases in weight
will often increase blood pressure an stress on vein
Prolonged Standing - The volume and pressure
of blood in the lower limbs is affected by gravity,
so the longer you stand the greater the effect.
Physical Trauma - Sometimes trauma to the lower
limbs can damage the underlying blood vessels and
add to the problem of vein reflux disease.
