What is the Origin of Sustained Growth Hormone Release?

This is a descriptive term from endocrinology, contrasting the natural, rhythmic "pulsing" release with a "sustained," or continuous, pattern. It highlights the importance of chronobiology and release kinetics in hormone action. The concept is used to differentiate physiological from non-physiological hormone exposure.

What is the Mechanism of Sustained Growth Hormone Release?

Unlike the physiological, pulsatile release controlled by the interplay of GHRH and Somatostatin, sustained release can overwhelm the pituitary-liver axis. Continuous exposure to high GH levels can lead to the downregulation of GH receptors on hepatocytes, resulting in reduced production of the key anabolic mediator, IGF-1. This paradoxical blunting of the anabolic signal, coupled with potential insulin resistance, underscores why the pattern of hormone release is as critical as the total quantity for therapeutic success.

Sustained Growth Hormone Release

Meaning

Sustained Growth Hormone Release refers to the continuous or prolonged, non-pulsatile secretion of Somatotropin, often resulting from a pathological condition or an inappropriately administered therapeutic regimen. While pulsatile release is the physiological norm, a sustained, flat-line elevation of Growth Hormone can paradoxically lead to receptor desensitization and blunted biological effects, potentially increasing the risk of adverse metabolic outcomes. This pattern contrasts sharply with the healthy, intermittent release necessary for optimal anabolic function.
