What does a non-stress test evaluate in a pregnant woman with diabetes?

A non-stress test (NST) primarily evaluates the fetal well-being during pregnancy. This test measures the fetal heart rate in response to movements, providing insights into how well the fetus is oxygenated and functioning. In pregnant women with diabetes, ensuring optimal fetal health is crucial because they are at a higher risk for complications, such as fetal distress or stillbirth. The NST helps in monitoring the baby's health, especially in the context of diabetes, where the balance of sugar levels can significantly impact fetal development and well-being.

The focus of the NST is not on the mother's insulin levels, the need for early delivery, or the presence of gestational diabetes. While these factors are also important in the overall management of a pregnant woman with diabetes, the primary purpose of a non-stress test is to assess the response of the fetal heart rate to stressors, ensuring that the fetus is thriving inside the womb.
