The postpartum phase represents a dynamic stage of immune restructuring, as the maternal immune system transitions from the pregnancy-induced tolerant state to an inflammatory and restorative profile. Advances in immunogenomic technologies, including single-cell and spatial gene expression profiling, epigenomic analysis, multiomic integration, immune receptor repertoire sequencing, and machine learning, now allow high-resolution mapping of these processes at molecular, cellular, and tissue levels. This review synthesizes current evidence on postpartum immune profiling, highlighting the rapid reversal of pregnancy-associated immunosuppression, hormone withdrawal, interactions between the microbiome and the immune system, and the formation of long-term reproductive immune memory. We examine how delivery mode (vaginal versus cesarean), genetic variants, epigenetic modifications, and non-coding RNAs contribute to divergent postpartum outcomes, including susceptibility to infection, autoimmune flares, hypertensive complications, postpartum depression, and delayed wound healing. Integrative immunogenomic studies have identified specific predictive biomarkers, such as sustained inflammatory signaling molecules (interleukin-6, tumor necrosis factor-alpha), cell-type-specific gene expression signatures, and microbiome-derived markers, that outperform conventional clinical variables in forecasting maternal complications. These biomarkers enable precision postpartum medicine by guiding individualized risk assessment, early diagnosis, and targeted interventions. However, significant gaps remain in longitudinal datasets, global cohort representation, standardization of methodologies, and clinical implementation, particularly in low-resource settings. Future directions include population-scale immunogenomic surveillance, artificial intelligence-driven predictive modeling, integration of wearable biosensors, and development of personalized postpartum care frameworks. By harnessing immunogenomic biomarkers, precision medicine can redefine maternal recovery and improve outcomes through tailored prevention and management of postpartum morbidity.
