Pregnant women’s blood glucose 5.48mmol/L needs to be based on the specific time of blood collection, if it is fasting blood glucose 5.48mmol/L is considered high, if it is postprandial blood glucose is within the normal range. The reference range of blood glucose varies during pregnancy due to metabolic changes in pregnant women. Under normal circumstances, the fasting blood glucose value should be less than 5.1mmol/L, 1 hour after meal blood glucose is less than 10.0mmol/L, 2 hours after meal blood glucose value is less than 8.5mmol/L. So if a pregnant woman’s fasting blood glucose is 5.48mmol/L, it is considered high, and if her postprandial blood glucose is 5.48mmol/L, it is within the normal range. It is recommended that pregnant women who have not been diagnosed with diabetes before pregnancy should have a glucose tolerance test in the 24th to 28th week of pregnancy, and pregnant women with hyperglycemia should be treated in a timely manner. Pregnant women with high blood glucose should be treated promptly. If the blood glucose is abnormal, it is recommended to consult a doctor in time, adjust the diet under the guidance of the doctor, or take appropriate treatment if necessary.
