Because PTSD creates a constant state of intense stress the body’s reaction to this causes neurobiological changes. Glucocorticoids, epinephrine, and norepinephrine pulse through the body as part of the normal reaction to stress. These chemicals are important for human survival but excessive amounts cause the brain to malfunction. Because of hyperarousal, the body of an individual suffering from PTSD gets too much of these chemicals, even when no threat is present. The chronic stress promotes physical ailments and a breakdown of the immune system. Other difficulties include increased heart rate and blood pressure, changes to the distribution of cortisol (affecting mood and energy levels), shrinking of the hippocampus (affecting learning and memory), and enlargement of the amygdala (affecting emotional behaviors). Extreme fatigue is a normal reaction under stress. Most stressed people will "try harder" to overcome their problems, when what they need most is "worry-free" rest.
