What is the Origin of Age-Related Endocrine Dysfunction?

The term draws its origin from the convergence of gerontology and endocrinology, observing that systemic aging is inextricably linked to changes in hormonal signaling pathways. The etymology combines 'age-related,' indicating time-dependent changes, with 'endocrine dysfunction,' referring to impaired internal secretion and regulation. This concept emerged from decades of clinical observation detailing the predictable decline of various glandular outputs in older adults.

What is the Mechanism of Age-Related Endocrine Dysfunction?

The dysfunction operates through several interconnected pathways, including reduced sensitivity of target tissues to circulating hormones due to receptor downregulation or post-receptor signaling defects. Furthermore, there is often a decrease in the pulsatile secretion of key trophic hormones, such as Growth Hormone and Gonadotropin-releasing hormone, which directly impacts downstream endocrine organ function. Chronic low-grade inflammation, or 'inflammaging,' also contributes significantly by disrupting hypothalamic and pituitary control mechanisms.

Age-Related Endocrine Dysfunction

Meaning

Age-Related Endocrine Dysfunction describes the progressive decline in the efficiency and responsiveness of the endocrine system that occurs with chronological aging. This physiological deterioration affects the production, secretion, transport, and action of various hormones, leading to a shift in homeostatic set points. Clinical manifestations include conditions such as somatopause, andropause, and menopausal transitions, reflecting a reduced capacity for adaptation and repair. Understanding this decline is crucial for maintaining metabolic and physical resilience across the lifespan.
