Gestational diabetes mellitus (GDM) was a common condition that arises during pregnancy, characterized by maternal hyperglycemia. It had significant implications for both maternal and neonatal health. Recent research has focused on how maternal hyperglycemia induces epigenetic changes in the fetus, potentially leading to long-term adverse health outcomes in offspring. This review explored the relationship between maternal hyperglycemia, epigenetic mechanisms, and adverse neonatal outcomes in GDM, with a focus on the underlying molecular mechanisms and the potential long-term consequences for offspring. A comprehensive review of current literature on GDM pathophysiology, epigenetic alterations, and neonatal outcomes was conducted, including studies on DNA methylation, histone modifications, and non-coding RNA regulation. Maternal hyperglycemia during pregnancy induced epigenetic modifications in the fetus that affect fetal development, leading to an increased risk of metabolic disorders, such as obesity and diabetes, in later life. These epigenetic changes often involve genes related to insulin signaling, metabolism, and growth. Understanding the epigenetic mechanisms induced by GDM offers potential therapeutic avenues for mitigating the long-term adverse effects on offspring. Future research should focus on identifying specific epigenetic markers and exploring potential interventions.
