Diabetes during pregnancy should be controlled by diet, exercise and insulin. 1. Diet: you should eat small meals and pay attention to nutritional balance, not only to ensure the caloric needs of the mother and fetus during pregnancy, but also to avoid hyperglycemia or starvation ketosis, and eat fewer snacks and beverages with high sugar content. 2. Exercise: Within the scope of physical permissibility, appropriate sports can be conducted to control the rate of weight gain, which can improve the situation of blood glucose. 3. Insulin therapy: patients with high blood sugar in pregnancy that is difficult to control and cannot control their blood sugar within the target range are recommended to receive insulin therapy under the guidance of a doctor, and oral hypoglycemic drugs are generally not used. 4. Others: Ensure adequate sleep, avoid excessive mental stress, and monitor blood glucose and blood pressure regularly. Diabetes during pregnancy should be treated actively and checked regularly.
