Trauma is a leading global cause of morbidity and mortality, traditionally understood as a localized physical injury. However, current evidence supports a broader perspective in which trauma triggers a complex systemic response involving inflammatory, neuroendocrine, immune, metabolic, and endothelial mechanisms. This study aimed to analyze Post-Traumatic Systemic Syndrome as an integrative condition that influences recovery beyond the initial injury. A structured narrative review was conducted using international scientific databases, including PubMed, Scopus, and Web of Science, focusing on high-impact literature related to systemic trauma responses. The analysis explored the interaction between inflammatory activation, neuroendocrine regulation, immune dysfunction, and metabolic alterations. The findings demonstrate that trauma induces an immediate inflammatory response characterized by cytokine release, followed by neuroendocrine modulation through activation of the hypothalamic–pituitary–adrenal axis. This interaction may lead to either balanced recovery or dysregulated states such as hyperinflammation, immunosuppression, and persistent inflammation syndromes. Additionally, endothelial dysfunction, coagulopathy, and mitochondrial impairment contribute significantly to systemic complications. Recovery trajectories vary depending on the regulation of these mechanisms, highlighting the importance of early and targeted interventions.
