Lucy Wang, a smart, capable, and beautiful expectant mother, sits in the doctor's office. At 25 weeks pregnant, her usual radiant joy has faded as she anxiously awaits her lab results. She has been diagnosed with gestational diabetes. She desperately wants to know: Why was she diagnosed with gestational diabetes after being healthy before pregnancy? What effects does gestational diabetes have on the mother and baby? Could it have been detected earlier? Is it treatable?More importantly, how can it be prevented?
Lucy Wang's concerns are actually quite common. Gestational diabetes refers to diabetes that develops or is discovered during pregnancy in women who had normal glucose metabolism or underlying impaired glucose tolerance before conception. As pregnancy progresses, the body produces increased levels of insulin-like substances, making gestational diabetes more likely to occur.Today, urban women tend to conceive at older ages, engage in less physical activity during work, and often consume excessive nutrition after pregnancy. These factors also contribute to the high incidence of gestational diabetes. The impact of gestational diabetes on both mother and fetus depends on the severity of the condition and the level of blood sugar control. Pregnant women with well-controlled blood sugar experience minimal effects on themselves and their babies. Those with poorly controlled blood sugar face greater risks for both mother and child.
Effects on the mother: May cause fetal developmental abnormalities or even death, leading to higher miscarriage rates. Increases the risk of gestational hypertension and infections such as vulvovaginal inflammation, pyelonephritis, asymptomatic bacteriuria, puerperal infections, and mastitis. Elevates the incidence of polyhydramnios. The increased likelihood of macrosomia can result in difficult labor and birth canal injuries.Increased likelihood of cesarean delivery, prolonged labor, and postpartum hemorrhage. Higher recurrence rate in subsequent pregnancies, with significant long-term risk of developing type 2 diabetes.
Effects on the fetus: High incidence of macrosomia (excessively large fetus) or intrauterine growth restriction (excessively small fetus). Increased risk of miscarriage, preterm birth, and congenital anomalies.
Effects on the newborn: Impaired respiratory function, hypoglycemia.
Early symptoms of gestational diabetes: Increased hunger, excessive eating and drinking, frequent urination. Treatment of gestational diabetes requires first recognizing its serious risks—it's not merely a minor issue like sugar in urine, but significantly impacts both mother and baby. Second, understand it is manageable. Most pregnant women with gestational diabetes can control blood sugar through education, dietary management under medical guidance, and increased physical activity.
Dietary management involves structuring meals around low-sugar, low-fat, moderate-protein foods rich in fiber. Opt for steaming or boiling over frying. Limit portion sizes per meal and increase meal frequency. Adjust food intake based on fasting and postprandial blood glucose monitoring. Medication becomes necessary if blood sugar remains uncontrolled.Currently, subcutaneous insulin injections are the primary medication for managing gestational diabetes in China. Insulin dosage varies significantly between individuals and changes throughout pregnancy, so it must be administered under strict medical supervision to prevent hypoglycemia or inadequate control.
Satisfactory blood glucose control during pregnancy is defined as: no significant hunger, fasting blood glucose between 3.3-5.6 mmol/L; 30 minutes before meals between 3.3-5.8 mmol/L; 2 hours after meals between 4.4-6.7 mmol/L; and overnight levels between 4.4-6.7 mmol/L.
Prevention of gestational diabetes: The body naturally produces increased insulin-like substances during pregnancy, which we cannot easily alter.However, we can reduce the body's burden through dietary control, eating smaller, more frequent meals. Simultaneously, appropriate exercise—such as post-meal walks or gentle calisthenics—can enhance glucose utilization, improve blood sugar levels, and delay or prevent the onset of diabetes. Should it occur, there's no need for excessive anxiety. Most pregnant women with gestational diabetes can manage it effectively under medical guidance through diet control and moderate exercise. With proper management, these women can still have a smooth delivery.
Lucy Wang smiled again upon hearing this explanation. She diligently jotted down the key points: watch her diet, eat smaller portions more frequently; get moving, exercise moderately; monitor blood sugar to track progress. It seemed pregnant women with gestational diabetes could lead lives much like those without it.
