What physiological responses may occur in PTSD sufferers when exposed to stimuli associated with past traumatic events?

Individuals suffering from Post-Traumatic Stress Disorder (PTSD) often experience heightened physiological responses when they are exposed to stimuli that remind them of their past trauma. When confronted with such triggers, the body can enter a state of hyperarousal as part of the fight-or-flight response.

This response is characterized by increased heart rate and elevated blood pressure as the body prepares to react to perceived threats. The adrenaline and cortisol released during this state can lead to various physical sensations, including palpitations and a rush of energy, as the individual instinctively readies themselves for danger. These physiological changes are natural reactions to stress and trauma, aiming to support survival in threatening situations. Recognizing these symptoms is essential in understanding the impact of trauma on the body, particularly in those with PTSD.

In contrast, the options representing increased appetite and energy levels, decreased heart rate and blood pressure, or increased fatigue and weakness do not accurately reflect the typical physiological responses associated with PTSD triggers. Such alternatives may relate to different medical conditions or psychological responses but do not align with the body's immediate reactions to traumatic reminders.
