Gestational diabetes refers to diabetes that appears or is diagnosed during pregnancy and is a distinct type of diabetes. Many women with gestational diabetes may see their blood sugar levels return to normal after delivery as insulin resistance diminishes. It is recommended to conduct an OGTT (oral glucose tolerance test) screening six weeks after childbirth, as the majority of women with gestational diabetes will have normal fasting blood glucose or OGTT values at six weeks postpartum. Approximately 25% to 70% of women with gestational diabetes may develop diabetes again within 16 to 25 years after delivery. Therefore, it is essential to continue monitoring the patient's blood glucose postpartum and to screen early for diabetes.
