The human body’s inflammatory response is an ancient protective mechanism, predating the nervous system itself. This fundamental biological link is crucial for understanding **why is inflammation a stress response**—a complex system designed to defend the body against perceived threats, from infections to psychological stressors.

Studies reveal that individuals with post-traumatic stress disorder (PTSD) have significantly elevated levels of inflammatory markers like C-reactive protein (CRP), interleukins, and tumor necrosis factor-α compared to healthy controls. This growing body of evidence helps to explain how does trauma cause inflammation, showing a profound and lasting connection between psychological stress and the body’s physical immune response.

Studies have shown that chronic stress is linked to a higher risk of heart disease, stroke, and obesity. This highlights the importance of understanding **what is the pathophysiology of stress**, the complex interplay of neurological and hormonal systems designed for survival.
