is a type of diabetes that some women get during pregnancy, usually around the 24th week. Between 5-7% of expectant mothers develop this condition, making it one of the most common health problems of pregnancy.
In pregnancy, the placenta produces hormones that help the baby grow and develop. These hormones can block insulin from doing its job, this is called insulin resistance. For most moms-to-be, this isn't a problem: When the body needs additional insulin, the pancreas dutifully secretes more of it. But if the pancreas can't keep up with the increased insulin demand during pregnancy, blood glucose levels rise too high, resulting in gestational diabetes. After the baby is born, the mother’s blood glucose levels usually return to normal.
Gestational diabetes generally has no symptoms, or the symptoms are mild. it is most commonly diagnosed by screening during pregnancy.
