The screening steps for gestational diabetes involve, for most women, the recommendation to undergo a 75-gram glucose tolerance test at the hospital between 24 to 28 weeks of pregnancy. The method includes fasting blood draw, consuming 75 grams of glucose, and monitoring blood sugar levels one hour and two hours after glucose intake, to determine the presence of gestational diabetes. However, for pregnant women at high risk for diabetes, it is recommended to complete the 75-gram glucose tolerance test early in pregnancy to detect gestational diabetes early and initiate treatment promptly to reduce the risks to both the fetus and the mother.

How is gestational diabetes treated?

The treatment of gestational diabetes includes dietary therapy, exercise therapy, and insulin therapy. For dietary therapy, we mainly control the total calorie intake and supplement with elements such as calcium, iron, folic acid, and various vitamins; in exercise therapy, we aim to control the speed of weight gain, improve the peripheral tissues' utilization of glucose, and improve the lipid profile. For patients whose blood glucose levels do not meet the standards after two weeks of diet and exercise therapy, we initiate insulin therapy. The goal of insulin therapy is to control fasting blood glucose below 5.3 and postprandial blood glucose below 6.7. The methods of insulin therapy include twice daily injections, multiple daily injections, or the use of an insulin pump.

What are the symptoms of a baby born to a mother with gestational diabetes?

During pregnancy, if a pregnant woman suffers from high blood glucose, it can potentially impact the fetus's growth and development. After the baby is born, this may result in a larger size of the fetus, and a decrease in the baby's immune system, making them more susceptible to infectious diseases. If high blood glucose occurs during pregnancy, it is important to control the diet promptly, eat less sugary food, and also control the portion of food. If necessary, medical treatment under the guidance of a doctor can also be conducted to maintain blood glucose at a stable level. If blood glucose is well-controlled during pregnancy, the baby will be just like other healthy babies after birth.

What is gestational diabetes?

The group of people who were diagnosed with diabetes before pregnancy is called gestational concurrent diabetes. Those who were not diagnosed with diabetes before pregnancy, but were diagnosed after becoming pregnant, are referred to as having gestational diabetes. Eighty percent of women are diagnosed with gestational diabetes, while twenty percent have gestational concurrent diabetes.

Effects of gestational diabetes on the fetus

The impact of gestational diabetes on the fetus mainly manifests in early stages as spontaneous miscarriage, fetal malformations, and abnormal fetal development. As the fetus grows, the high maternal blood sugar levels can lead to a large fetus, which increases the risk of birth injuries during delivery. Due to the high insulin levels in the mother, the fetus may have hyperinsulinemia, which can cause recurrent hypoglycemia at birth. Additionally, the development and maturation of the fetal lungs are delayed, making the newborn more susceptible to respiratory distress syndrome. Furthermore, gestational diabetes also increases the risk of preterm birth.
