For diabetes during pregnancy, it is important to manage the condition in pregnant women. Initially, for blood sugar control during pregnancy, we recommend that the blood sugar levels before meals and two hours after meals be less than or equal to 5.3 mmol/L and 6.7 mmol/L, respectively, and nighttime blood sugar levels should not be lower than 3.3 mmol/L.

For patients with diabetes complicated by pregnancy, the blood sugar control during pregnancy should meet the following targets: early pregnancy blood sugar control does not need to be overly strict to prevent hypoglycemia. Blood sugar levels before meals and during the night, as well as fasting blood sugar, should be controlled between 3.3 to 5.6 mmol/L, and post-meal peak blood sugar levels should be between 5.6 to 7.1 mmol/L. For both diabetes during pregnancy and diabetes complicated by pregnancy, if blood sugar levels cannot meet the above standards through diet and exercise management, insulin or oral hypoglycemic drugs should be used for further blood sugar control.

Pregnancy is a special physiological period, and blood sugar control in diabetic pregnant women must not only be within the normal range but also ensure reasonable nutrient intake for the mother and fetus, reducing the occurrence of maternal and fetal complications. Most patients with gestational diabetes can control their blood sugar satisfactorily through reasonable dietary control and appropriate exercise therapy. The total daily nutrient intake should be determined based on the weight before pregnancy and the rate of weight gain during pregnancy.
