Physiological Threshold Management is the clinical practice of identifying, monitoring, and strategically modulating the specific biological limits at which a physiological system transitions from a state of adaptation and resilience to one of decompensation and pathology. This management focuses on keeping key health indicators safely below critical limits, such as the glycemic threshold for insulin resistance or the stress threshold for HPA axis burnout. It is a proactive strategy for disease prevention and maximizing healthspan. Exceeding these thresholds initiates a cascade of detrimental effects.
Origin
The concept stems from stress physiology, toxicology, and systems biology, where the “threshold” represents the point of irreversible change or damage. In a clinical context, “management” implies the therapeutic control of variables that push the system toward that limit. This framework allows clinicians to intervene before measurable pathology develops. It is a core principle of preemptive medicine.
Mechanism
The process involves continuous assessment of biomarkers that serve as proxies for systemic stress and reserve capacity, such as Heart Rate Variability (HRV), inflammatory markers, and specific hormone ratios. By implementing targeted interventions—like reducing chronic psychological stress or improving metabolic flexibility—the clinician aims to increase the system’s overall capacity. This effectively moves the pathological threshold further away from the patient’s baseline function, thereby enhancing resilience.
