What causes gestational diabetes?
Insulin is an important hormone that controls blood glucose levels. Normal pregnancy hormones that are produced by the placenta reduce the actions of insulin in the mother's body, an effect known as insulin resistance. If not enough insulin is produced to compensate for the insulin resistance, blood glucose levels will remain abnormally high, as seen in gestational diabetes.
