Gestational diabetes

Gestational diabetes includes pregnancy in diabetic patients (ie, diabetes with pregnancy), and gestational diabetes. Gestational diabetes mellitus (GDM) is hyperglycemia caused by different degrees of impaired glucose tolerance and diabetes, which is found or developed during pregnancy. According to its definition, this type of diabetes includes two types that existed before pregnancy but were diagnosed during pregnancy and occur during pregnancy. It also includes both diabetes, impaired glucose tolerance (IGT), and fasting Impaired glucose (IFG). Gestational diabetes is a high-risk pregnancy, which seriously endangers the health of mothers and children. Before the advent of insulin, maternal mortality was 27 to 30%, and fetal perinatal mortality was 40%. After the advent of insulin, especially since the development of perinatal medicine, the perinatal mortality rate has decreased significantly.
