Introduction to the latest standards for normal blood sugar levels in pregnant women. The latest standards for normal blood sugar levels in pregnant women refer to the control of blood sugar in pregnant women within the normal range during pregnancy, placenta production and childbirth, ensuring the normal development of the fetus and the health of the mother. At present, the normal blood glucose standards for pregnant women at home and abroad mainly refer to the research results released by the International Pregnancy Diabetes Study Group (IADPSG) and the Gynecology Branch of the Chinese Maternal and Child Health Association (CMA). The IADPSG standard believes that pregnant women’s fasting blood sugar is 5.1 mmol/L and above.
