Pregnant women with gestational diabetes must have their blood glucose rechecked 4-12 weeks postpartum to clarify the presence of postpartum blood glucose abnormalities. Among patients with high blood glucose or diagnosed diabetes during pregnancy, about 30% will show abnormal blood glucose after delivery, 90% of which are pre-diabetic and can progress to diabetes in 2-3 years without intervention. On the contrary, if the intervention is well controlled, it can return to normal. Some people find gestational diabetes very seriously when they are pregnant, daily finger-tying 5-6 times to measure blood glucose, are adhering to a very good, never lazy. But after the baby was born, the doctor asked before the postpartum review of blood glucose instructions do not care, so it is easy to unknowingly develop into a diabetic. Therefore, pregnant women with gestational diabetes must undergo a blood glucose review 4-12 weeks after delivery to determine if there is a postnatal blood glucose abnormality. If the blood glucose is abnormal, active dietary control and lifestyle intervention are required. 3-6 months of lifestyle intervention is not effective, medication should be used. People with normal blood glucose after delivery still need to monitor their blood glucose regularly, and once abnormal blood glucose is detected, they need to intervene as soon as possible to prevent the disease from progressing and to prevent the occurrence of diabetes mellitus.
