What is the Origin of Somatopause Decline?

The term synthesizes "somato-," from the Greek "soma" (body), referring to growth hormone's systemic effects, with "-pause," signifying a cessation or reduction, analogous to menopause or andropause. This designation highlights the systemic impact of the declining somatotropic axis on body composition and vitality, establishing it as a distinct age-related endocrine phenomenon.

What is the Mechanism of Somatopause Decline?

The decline is primarily mediated by changes in the hypothalamic-pituitary axis, specifically a reduction in the amplitude and frequency of Growth Hormone-Releasing Hormone pulses and an increase in somatostatin tone, which inhibits GH release. The subsequent lower GH secretion leads to a reduction in IGF-1 production by the liver. This systemic reduction in the somatotropic signal impairs anabolic processes, contributing to sarcopenia and altered fat distribution.

Somatopause Decline

Meaning

Somatopause Decline is the clinical term for the progressive, age-related reduction in the pulsatile secretion of Growth Hormone (GH) and the subsequent decrease in circulating Insulin-like Growth Factor 1 (IGF-1) that occurs in middle to later adulthood. This endocrine change is associated with several physiological alterations, including decreased lean body mass, increased central adiposity, and reduced bone mineral density. Recognizing this decline is essential for addressing the changes in body composition and metabolic function that accompany aging.
