Women who have had gestational diabetes have a 35 -60 percent chance of developing diabetes in the next 10-20 years. .
New diagnostic criteria for gestational diabetes will increase the proportion of women diagnosed with gestational diabetes. It is estimated that 18 percent of all pregnancies are affected by gestational diabetes.
