When is gestational diabetes usually screened during pregnancy?

Gestational diabetes screening is typically performed between 24 and 28 weeks of gestation. This timing is critical because it aligns with the period when hormonal changes in the mother's body can lead to insulin resistance, increasing the risk of developing gestational diabetes.

Screening during this window allows for early identification and management of the condition, helping to mitigate risks to both the mother and the developing fetus. It is important because untreated gestational diabetes can lead to complications such as high birth weight, preterm birth, and an increased likelihood of developing type 2 diabetes later in life for both the mother and child.

Earlier or later screening times, such as at 20-24 weeks or after 30 weeks, are not aligned with the standard recommendations due to the physiological changes that occur around the specified timeframe.
