The Endogenous Opioid System Controls How the Body Responds to Stress Hormones
Endogenous opioid peptides (endorphins, enkephalins, dynorphins) modulate the HPA stress axis response, with opioid system disruption (from chronic pain, addiction, or stress) altering stress hormone reactivity.
Quick Facts
What This Study Found
Endogenous opioid peptides regulate HPA axis stress reactivity through hypothalamic CRF and ACTH modulation, with opioid system disruption producing altered cortisol responses — explaining stress hormone dysregulation in chronic pain, addiction, and stress disorders.
