(Ivanhoe Newswire) -- Women who experience diabetes while they're
pregnant are significantly more likely to develop type 2 diabetes following the
birth of their child.
According to Canadian and U.S. researchers who followed 659,000 women, including
more than 21,000 with gestational diabetes, for nine years, the incidence of
type 2 diabetes was nearly 20 percent in women who had the condition while
pregnant. The incidence in women who didn't experience gestational diabetes was
just two percent.
The authors believe these findings suggest a need for better care and follow-up
screenings for women who experience gestational diabetes. In an accompanying
commentary, Dr. David Simmons, of Cambridge University Hospitals NHS Foundation
in the United Kingdom, agrees, pointing out women with gestational diabetes
often go on to have more children and may enter into another pregnancy with
undiagnosed type 2 diabetes. That could put both mother and baby at risk,
because women with type 2 diabetes are known to experience higher levels of
miscarriage, and their infants are more likely to suffer from birth defects or
die soon after birth.
In the current study, the rate of type 2 diabetes increased rapidly in the first
nine months following delivery in women with gestational diabetes. Incidence of
the disease peaked nine years following the birth of the child.
