Maternal hyperglycemia, which refers to elevated blood glucose levels during pregnancy, is known to have significant effects on the developing fetus and can lead to various neonatal complications. One of the recognized complications of maternal hyperglycemia is an increased risk of respiratory distress syndrome (RDS) in newborns.

RDS is primarily associated with neonatal prematurity and insufficient surfactant production in the lungs. Surfactant is a substance that helps reduce surface tension in the alveoli and is crucial for normal respiration after birth. When a mother has hyperglycemia, especially in cases of gestational diabetes or poorly controlled pre-existing diabetes, it can lead to metabolic imbalances and result in greater fetal insulin levels. High insulin levels in the fetus have been linked to delays in the production of surfactant, thereby increasing the risk of RDS.

Additionally, maternal hyperglycemia can contribute to fetal macrosomia, which might increase the likelihood of cesarean delivery and prematurity, both of which are independent risk factors for developing respiratory problems in newborns. Therefore, the relationship between maternal hyperglycemia and the risk of respiratory distress syndrome is well-documented, highlighting that an infant born to a mother with elevated blood glucose levels is at an increased risk for this
