We can all recognise the dark blue or purple, enlarged, lumpy and
twisted veins that we know to be Varicose Veins (or Varicosities). Women are more susceptible to these with around
30% of women developing them at some stage.
There is an increased risk especially during pregnancy, partly because
of the additional weight and pressure that the legs experience as a result of
carrying the baby. This necessitates the
veins to work harder due to increased blood flow which may cause them to become
swollen, but also because the hormones produced in pregnancy can cause the
walls of the veins to weaken.
Other symptoms can include dry skin and colour changes to the legs and
they can also cause cramp. They can feel
achy and/or itchy and can cause swelling to the feet and ankles.
But what are Varicose Veins, what are the causes and should we be
worried if we develop them?
There are valves within the leg veins.
Their purpose is to ensure that the blood flows correctly round the body
and does not reverse its course and return to the heart too early. If these valves become damaged it is possible
for blood to pool in the legs and this is what becomes visible as Varicose
Veins. They can be sore and
uncomfortable for the sufferer although they are mainly a cosmetic problem
rather than a serious medical condition.
Standing for long periods in at work can cause the veins to become
swollen and enlarge which could trigger them but there is also a congenital predisposition. Another reason is age
related as the valves which restrict the backward blood flow become weaker with
age, so the likelihood of being affected is increased.
Although they are unsightly and sometimes uncomfortable, Varicose Veins
are not dangerous. However, once they
appear there are no quick fix remedies to eradicate them. Although it may be possible to slow down the
risk of developing more by exercise, by elevating the feet/legs
when sitting so blood can’t pool in the lower extremities and by avoiding being
overweight. Not continually standing for long
periods will also go some way to having a remedial effect and some Doctors may
recommend support tights or stockings.
For anyone determined to have them removed laser treatments are available. there is also, a procedure called ‘Sclerotherapy’,
which involves injecting a special foam into the enlarged vein which causes it
to wither. However, this is not
guaranteed successful first time and could require more than one treatment and
some people could experience minor side effects or complications. Your Doctor can advise you of what’s involved
but it’s unlikely that NHS treatment will be offered. Treatment would probably have to be done
privately.
