A new study suggests that a genetic link could explain why some women who develop miscarriages develop cold veins.
Researchers in Sweden say that cold veins are present in about 30% of miscarriages.
This means that around 1 in every 10 women who have a miscarriage suffer from them.
The researchers have found that women who suffer from cold veins also have an increased risk of having another miscarriage.
“The genetic component of cold veins has been suggested to be a possible explanation for why cold veins occur in some women,” the researchers wrote.
Women who suffer a miscarriage develop cold symptoms and it is not clear whether this is related to the cold veins or the underlying reason.
But, they say, “the presence of cold-veins in some patients and the association with cold-vascular symptoms in some other patients suggest that cold-venous syndrome may be a risk factor for a second miscarriage.”
Researchers say the researchers also have identified a gene that may be involved in the development of the cold-vessel syndrome.
These genes are present on chromosome 16.
Scientists hope that this new study will lead to better ways to prevent miscarriages and may help to reduce the risk of miscarriage.
