Functional Inadequacy Threshold

Meaning

The Functional Inadequacy Threshold defines the specific physiological or biochemical point at which a system, such as the endocrine or immune system, can no longer compensate for a deficiency or stressor, resulting in measurable functional decline or symptom presentation. This threshold is typically far above the levels defined by standard clinical pathology, representing a state of sub-optimal function rather than overt disease. Identifying this personalized limit is critical for proactive, preventative health management and is a cornerstone of functional endocrinology. It represents the limit of the body’s adaptive reserve.
