Blood Glucose in Pregnant Non-diabetic Women During Treatment With Betamethasone for Fetal Lung Maturation

In case of threatening preterm birth, it is standard to recommend treatment with betamethasone to accelerate fetal lung maturation. In pregnant women with diabetes, treatment with betamethasone can lead to significant hyperglycemia, which may cause hypoglycemia in the neonate. Changes in blood glucose in non-diabetic women are less investigated. In this study we aim to examine changes in maternal blood glucose levels in non-diabetic women, during treatment with betamethasone, by continuous glucose monitoring. Hypotheses: Administration of betamethasone induce significant hyperglycemia in non-diabetic pregnant women during treatment.
