Catabolic Stress Response

Meaning

The Catabolic Stress Response is a coordinated physiological reaction, primarily mediated by stress hormones, characterized by the breakdown of complex molecules into simpler ones to mobilize energy reserves. This essential survival mechanism is acutely beneficial for immediate energy demands but becomes detrimental when chronically activated, leading to muscle wasting and bone demineralization. Clinically, it represents a state of prolonged negative energy balance and tissue breakdown.
