What is DVT and please explain the effects on pregnancy?
DVT or deep vein thrombosis is caused by several factors,
and pregnancy is one of them. Every one in a thousand
pregnant women develop this problem during pregnancy.
Those with DVT previously, and are now pregnant, the
condition increases in gravity. It is basically a blood
clot, mostly in the deep leg vein, which is not visible
to the naked eye (i.e. different from the varicose veins
which we can see). The larger veins in the legs supply
blood to the smaller veins and blood flow is eased by
our leg movements and so when we stay immobile for longer
periods, this condition develops where blood flow is
partially or totally blocked by the clot.
Traveling long distances in flight is the main culprit
as staying immobile for hours causes the flow of blood
in the legs to slow down and clot instead. It is therefore
important to take short walks (in a smooth flight),
stretch your legs so that the clotting of the veins,
especially in the calves do not occur. The problem usually
resurfaces with women who have had DVT in the past and
are now pregnant. Flying should be avoided and doctors
rightfully advice against travel because both air-travel
and pregnancy increase the risk of DVT and clotting.
In a gist it is best for women with DVT to heed their
doctor's advice, and not fly.
