What is the Origin of Catabolic Hormone Override?

The term integrates concepts from general endocrinology, specifically the balance between anabolism (building up) and catabolism (breaking down) within human metabolism. The "override" aspect highlights a pathological or chronic imbalance where the stress-response hormones exert a disproportionate and sustained influence over tissue maintenance. This is fundamentally linked to the body's ancient fight-or-flight response inappropriately maintained in a modern context.

What is the Mechanism of Catabolic Hormone Override?

The override mechanism involves the sustained elevation and subsequent binding of catabolic hormones to their nuclear and membrane receptors in target tissues. Cortisol, for example, promotes protein degradation in muscle to supply amino acids for hepatic gluconeogenesis, while simultaneously inhibiting anabolic pathways like protein synthesis. This chronic signaling shifts the entire metabolic landscape towards resource depletion, ensuring immediate energy availability at the long-term expense of structural integrity and hormonal balance.

Catabolic Hormone Override

Meaning

Catabolic Hormone Override describes a physiological state where the destructive actions of catabolic hormones, primarily cortisol and glucagon, dominate anabolic processes, leading to the breakdown of complex molecules like muscle protein and stored fat. This override often occurs during periods of chronic stress, intense caloric restriction, or prolonged illness, creating a systemic deficit. Clinically, this sustained state impedes recovery, compromises immune function, and contributes to sarcopenia and metabolic dysfunction.
