Age-Related Vitality Decline

Meaning

This clinical term refers to the progressive, multi-systemic reduction in energy, physical capacity, and overall zest for life that correlates directly with the aging process. It is characterized by measurable decreases in hormonal output, diminished mitochondrial function, and a reduction in the body’s physiological reserve. The decline is not merely a subjective feeling but a quantifiable reduction in homeostatic resilience and energetic efficiency across multiple organ systems.
