Why does chronic stress disrupt the endocrine system's hormone balance?

💡 Explanation

Chronic stress activates the hypothalamic-pituitary-adrenal (HPA) axis, leading to sustained cortisol release. This sustained release interferes with the normal cortisol negative feedback loop, because the pituitary becomes less responsive to cortisol. Therefore, hormone balance is disrupted, rather than enhanced insulin sensitivity.
