Emerging biomarkers in diabetes offer promising avenues for early detection, risk assessment, and personalized management. Beyond traditional markers like HbA1c and fasting glucose, novel biomarkers—including inflammatory mediators, adipokines, genetic markers, and metabolomic profiles—are being studied to better predict disease onset, progression, and complications. These biomarkers enable more precise risk stratification, facilitate timely interventions, and guide individualized treatment strategies. Integration of biomarker data with clinical, lifestyle, and digital health information can enhance predictive accuracy, optimize therapy selection, and improve long-term outcomes. By leveraging emerging biomarkers, healthcare providers can move toward a precision medicine approach in diabetes care, improving early detection, monitoring, and overall patient management.
