Gestational diabetes refers to hyperglycemia that starts or is first identified during pregnancy, including previously undiagnosed glucose intolerance and diabetes before pregnancy. Although most patients’ blood sugar levels may return to normal after delivery, whether or not it normalizes postpartum, it is considered gestational diabetes. The harm during pregnancy endangers the health of both the fetus and the mother. The effects on offspring mainly manifest in the following ways: First, it increases the risk of complications such as fetal intrauterine death and congenital anomalies. Second, the risk of giving birth to a large baby is increased. Third, the incidence of neonatal hypoglycemia, jaundice, polycythemia, and hypocalcemia increases. Fourth, the risk of obesity, glucose intolerance, and diabetes increases during adolescence and young adulthood. Therefore, while gestational diabetes is not inherited by the baby, it does increase the risk of obesity, glucose intolerance, and diabetes in the baby during adolescence or young adulthood.

Gestational diabetes standard values

Standards for gestational diabetes, so what is gestational diabetes? It refers to diabetes that either develops during pregnancy or is first detected at this stage, presenting varying degrees of hyperglycemia, including previously unrecognized glucose intolerance or diabetes prior to pregnancy. Pregnancies in known diabetic patients are not included in this category, and may also be referred to as diabetes complicating pregnancy. So, how is gestational diabetes diagnosed? We can conduct a 75g anhydrous glucose tolerance test, where a fasting blood glucose greater than or equal to 5.1 mmol/L, and blood glucose greater than 10 mmol/L one hour after, meets the criteria to diagnose gestational diabetes.

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.

Gestational diabetes hazards

The hazards of gestational diabetes: So, what is gestational diabetes? It refers to the onset of varying degrees of hyperglycemia during pregnancy, or its first detection, including previously undetected glucose tolerance abnormalities and diabetes before pregnancy. However, pregnancies in diabetic patients are not included in this category, and should be referred to as diabetes complicating pregnancy. The main dangers of gestational diabetes are that it can jeopardize the health of both the fetus and the mother. The effects and hazards to offspring mainly manifest as an increased risk of fetal intrauterine death, congenital anomalies, and complications. There is also an increased risk of macrosomia, and an increased incidence of neonatal hypoglycemia, jaundice, polycythemia, and hypocalcemia. Additionally, the risk of obesity, glucose tolerance abnormalities, and diabetes significantly increases in offspring during adolescence or young adulthood.

How to self-test for gestational diabetes

Gestational diabetes refers to conditions where there was no diabetes before pregnancy, and during the course of the pregnancy, specifically between the 24th to 28th weeks, a standard glucose tolerance test is conducted to screen for glucose metabolism. The specific procedure involves not eating after 8 p.m. the night before, though drinking water is allowed, followed by fasting for more than ten hours. The first blood sample is taken on an empty stomach. Then, 75 grams of anhydrous glucose, as prescribed by the doctor, is dissolved in 250 to 350 milliliters of water and consumed within 3 to 5 minutes. Starting from the first sip of this glucose solution, blood samples are taken again one hour and two hours later. The results from these three blood samples are used to determine the possibility of gestational diabetes.

What to eat for breakfast with gestational diabetes

Patients with gestational diabetes are encouraged to have a balanced diet for breakfast, ensuring sufficient nutrient intake while choosing foods with a low glycemic index. For example, breakfast can include an egg, half a corn cob, a small meat bun, and a cup of milk. About two hours after breakfast, a snack can be added, selecting fruits with a low glycemic index such as strawberries, cherries, plums, apricots, apples, peaches, oranges, and grapefruits. This means that breakfast and the snack should include carbohydrates, vitamins, and proteins. Additionally, avoid eating porridge for breakfast as it has a high glycemic index, which can significantly raise blood sugar levels after the meal. Also, avoid overly greasy foods as they too can cause an increase in blood sugar.
