Gestational diabetes is increasingly common now as living standards improve, and there is more attention on pregnant women from their families. Often, out of fear of malnutrition during pregnancy, there is a tendency to over-nourish and overeat, leading to significant weight gain around the 24th to 26th weeks of pregnancy. Upon examination, it is discovered that their blood sugar levels are elevated, indicating gestational diabetes. Although gestational diabetes is becoming more widespread, the blood sugar levels are usually not extremely high. Therefore, such patients can often manage their condition through diet control and encouraging appropriate exercise for pregnant women. Thus, pregnant women diagnosed with gestational diabetes should not be overly stressed psychologically.

Do you need insulin for gestational diabetes?

Gestational diabetes refers to the elevated blood glucose levels found during pregnancy. For patients diagnosed with gestational diabetes, we first need to control diet and exercise to manage blood sugar levels, maintaining fasting blood glucose between 4.0-5.3 mmol/L and postprandial (two hours after meals) blood glucose between 4.4-6.7 mmol/L. If blood sugar control can be achieved through diet and exercise, insulin treatment is not required. However, if blood sugar levels still do not meet the standards through diet and exercise, exceeding the figures mentioned earlier, insulin treatment is necessary. For patients receiving insulin treatment, it poses no harm to either the fetus or the mother. In fact, when blood sugar is well-controlled, it can actually reduce the risks associated with gestational 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.

Harms of Gestational Diabetes

What is gestational diabetes? Gestational diabetes is a condition of varying degrees of high blood sugar that occurs or is first identified during pregnancy, including impaired glucose tolerance and diabetes that were not identified before pregnancy. Gestational diabetes can endanger the health of both the fetus and the mother. The impacts on offspring mainly include an increased risk of fetal mortality in the womb, i.e., an increased risk of complications from congenital abnormalities, an increased risk of macrosomia, and an increased risk of neonatal hypoglycemia and developing diabetes or impaired glucose tolerance during adolescence or young adulthood.

What are the symptoms of gestational diabetes?

Diabetes during pregnancy, compared to diabetes outside of pregnancy, still presents symptoms such as polydipsia, polyphagia, and polyuria, but does not manifest as weight loss. Due to the increase in body weight from the enlarging uterus, fetus, and amniotic fluid during pregnancy, signs of weight loss are not evident. There are generally two types of diabetes in pregnancy. One is when diabetes pre-exists before pregnancy, which is termed diabetes mellitus with pregnancy; the other is when blood sugar levels were normal before pregnancy and diabetes develops during pregnancy, known as gestational diabetes. Over 90% of pregnant women with diabetes have gestational diabetes. Those with gestational diabetes have abnormal glucose metabolism, but most can return to normal after childbirth; however, the risk of developing Type 2 diabetes in the future increases.
