Screening for gestational diabetes is typically performed between 24 and 28 weeks of pregnancy. During this period, insulin resistance caused by pregnancy-related hormones becomes more pronounced, making abnormalities in blood glucose easier to detect.
For pregnant women at higher risk, doctors may recommend blood glucose testing earlier, including during the first prenatal visits.
Skipping gestational diabetes screening may allow the condition to go undetected and untreated. This is particularly concerning because gestational diabetes often causes no noticeable symptoms.
Potential complications include having a large baby, difficult delivery or birth injuries, preterm birth, low blood glucose in the newborn, and an increased likelihood of cesarean delivery.
When gestational diabetes is detected early through appropriate testing and managed promptly, the risk of these complications can be significantly reduced.
Yes. Gestational diabetes has been associated with a higher risk of preeclampsia and other hypertensive disorders during pregnancy. Therefore, pregnant women with gestational diabetes should have both their blood glucose and blood pressure monitored throughout pregnancy.
However, an individual’s risk of developing gestational diabetes also depends on several other factors, such as obesity, obstetric history, and underlying medical conditions.
