For diabetic patients, the timing of delivery and the manner of delivery are particularly important. For example, if the glycemic control is satisfactory, it is possible for the pregnant woman to wait for a full-term spontaneous delivery, which is the termination of pregnancy at 38-40 weeks of pregnancy. In general, if there are no complications, the pregnancy can be terminated at 37-39 weeks, and the timing of delivery should be individualized. If the glycemic control is less than satisfactory, the pregnancy should be terminated earlier, after the fetal lungs have matured. For example, the American Diabetes Association recommends termination of pregnancy at about 38 weeks of gestation, unless there are other reasons, such as obstetric reasons, that require early termination of pregnancy. Gestational diabetes is not a condition or an indication for cesarean delivery. However, cesarean section should be considered for termination of pregnancy in the following cases, such as diabetes combined with microangiopathy or acute vascular disease, such as metabolic complications, and mild to moderate preeclampsia, and obstetric indications, such as a huge baby, which requires a cesarean section. In short, it is necessary to take an individualized plan for this delivery, depending on whether the pregnant woman has any complications, whether her blood sugar is satisfactorily controlled, or whether there are other obstetric conditions, to decide the time of delivery and the mode of delivery.
