← Human Body & HealthWhy does chronic stress disrupt the endocrine system's hormone balance?
A)Reduced red blood cell count
B)Dysregulation of cortisol feedback✓
C)Increased bone mineral density
D)Enhanced insulin sensitivity response
💡 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.
