Abstract

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.
