The normal value of postpartum fasting blood glucose is 3.9~6.0mmol/L. The normal range of postpartum blood glucose should be the same as the normal range of normal adult blood glucose, which is generally 3.9~6.0mmol/L for fasting blood glucose and <7.8mmol/L for 2 hours after meal. If the patient suffers from gestational diabetes before delivery, the blood glucose can usually return to normal after delivery, but the risk of type 2 diabetes in the future has increased. Therefore, patients with gestational diabetes should have their blood glucose rechecked regularly after delivery, so that abnormalities in blood glucose can be detected in time, and treatment can be intervened as early as possible. In daily life, it is recommended to continue to maintain a healthy lifestyle, control the total daily intake and exercise appropriately. For more information, please contact your doctor.
