Patient's question:
I am 29 weeks pregnant, and my 100g glucose tolerance test didn't pass. The doctor said to test my blood sugar at home. A post-meal 2-hour reading below 6.7 mmol/L is considered normal. However, I looked at the blood glucose meters on the market, and they all say a post-meal 2-hour reading below 7.8 mmol/L is normal.Doctor's answer:
Hello: Gestational diabetes is different from blood sugar levels at other times. It is recommended to recheck fasting blood sugar and perform a glucose tolerance test. Fasting blood sugar ≥ 5.8 mmol/L, 1-hour blood sugar ≥ 10.6 mmol/L, 2-hour blood sugar ≥ 9.2 mmol/L, and 3-hour blood sugar ≥ 8.1 mmol/L. If two or more of these criteria are met, it can be diagnosed as gestational diabetes.The impact of gestational diabetes on pregnancy: Gestational diabetes increases the risk of miscarriage, preterm birth, and stillbirth. The incidence of polyhydramnios also increases by 10% to 30%. The incidence of macrosomia increases, and the chances of dystocia and birth injuries during delivery will also increase. Due to reduced glucose utilization in gestational diabetes patients, labor may be prolonged during delivery, leading to a higher risk of uterine atony bleeding.
Gestational diabetes increases fetal mortality, primarily due to elevated blood sugar levels in the pregnant woman. Good blood sugar control can reduce fetal mortality. Infants born to gestational diabetes patients have a six times higher risk of developing neonatal respiratory distress syndrome compared to infants born to non-diabetic mothers. Neonates are also prone to neonatal hypoglycemia. Under stable blood sugar control, this is not a significant issue. However, it is important to have a correct understanding of diabetes—diabetic patients can marry and have children just like healthy individuals.
During pregnancy, insulin therapy is recommended. Oral hypoglycemic drugs and high blood sugar toxicity can easily lead to fetal malformations or miscarriage. It is recommended that you seek further detailed examination at a diabetes specialty hospital to accurately evaluate your condition, receive individualized treatment based on standardized guidelines, and achieve precise dynamic control.
Wishing you a speedy recovery!
