Stress and Hormones

Meaning

Stress and Hormones describes the profound physiological interaction where psychological or physical stressors trigger the activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis, resulting in the secretion of key regulatory hormones, predominantly cortisol and catecholamines. This acute response is designed for survival, but chronic dysregulation leads to systemic disruption, often suppressing the Hypothalamic-Pituitary-Gonadal (HPG) axis and impairing insulin sensitivity. It represents the body’s integrated response to perceived threat.
