Pregnant women with normal glycosylated hemoglobin may need to continue to control sugar, and need to improve the fasting blood sugar, postprandial blood sugar and other indicators to further determine. Glycated hemoglobin is formed by combining hemoglobin and glucose in red blood cells. Its value can reflect the average level of blood glucose in the body in the last 8 to 12 weeks, and it is a more stable test for assessing the effect of long-term blood glucose control. Combined with fasting blood glucose, postprandial blood glucose and other indicators, it can better assess the patient’s blood glucose situation or treatment effect. The diet of pregnant women should be nutritionally balanced, with scientific and rational combination of protein, fat, vitamins, carbohydrates and other nutritional intake. Regular medical checkups are recommended for pregnant women.
