Background: Emerging evidence suggests that the maternal microbiome plays a crucial role in shaping fetal neurodevelopment, immune programming, and metabolic health. Dysbiosis during pregnancy—whether gastrointestinal, oral, or vaginal—can significantly influence pregnancy outcomes and long-term child health. Materials and Methods: The search was performed using databases such as PubMed, Scopus, and Google Scholar including research published from January 2000 to January 2025. The keywords used were “Fetal Programming”, “ Maternal Immune Activation”, “Maternal microbiome”, “Microbiota–Gut–Brain Axis”, and “Pregnancy Dysbiosis”. Results: The maternal microbiome undergoes substantial changes during pregnancy, with alterations in microbial diversity and function linked to conditions such as gestational diabetes, obesity, and preeclampsia. Pregnancy-related dysbiosis has been associated with adverse neurodevelopmental outcomes, including an increased risk of autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and cognitive impairments in offspring. Conclusions: Understanding the intricate relationship between maternal microbiota and fetal health is essential for developing targeted interventions. Personalized microbiome-based strategies, including dietary modifications and probiotic supplementation, hold promise in optimizing pregnancy outcomes and promoting health in offspring.
