The best time to check for gestational diabetes is between 24 and 28 weeks of pregnancy.

Gestational diabetes is one of the diseases unique to pregnancy. Most pregnant women with this disease can recover to normal naturally after delivery, but gestational diabetes is very harmful to both pregnant women and babies. In recent years, the incidence of gestational diabetes in my country has increased significantly.

Because blood sugar fluctuates greatly during pregnancy, the timing of diabetes screening is special. In the early stages of pregnancy, as the gestational age increases, the fetus's demand for nutrition gradually increases. The fetus' energy source in the early stages of pregnancy is mainly obtained from the mother's glucose to meet its needs. Therefore, pregnant women often experience low blood sugar in the early stages of pregnancy. When the amount of insulin-antagonizing substances in the pregnant woman's body increases in the middle and late stages of pregnancy, the pregnant woman's sensitivity to insulin decreases, leading to an increase in the need for insulin. If the pregnant woman cannot compensate for this change in blood sugar, she is likely to develop gestational diabetes.

Adverse effects of gestational diabetes on mother and child:

1. High blood sugar can lead to abnormal and deformed fetal development, cause miscarriage, or even fetal death.

2. The risk of secondary gestational hypertension increases.

3. Various infections are prone to occur during pregnancy.

4. Excessive amniotic fluid.

5. The occurrence of macrosomia leads to an increased incidence of birth canal injury and dystocia during delivery.

6. The fetus is prone to growth restriction.

7. Newborns are prone to hypoglycemia.

8. Neonatal respiratory distress syndrome has occurred.

9. The incidence of diabetes in children increases significantly.
