Growth Hormone Pulse

Meaning

A Growth Hormone Pulse refers to the discrete, episodic burst of Growth Hormone (GH) secretion from the anterior pituitary gland, which is a defining characteristic of the somatotropic axis’s neuroendocrine rhythm. This pulsatile release, rather than continuous secretion, is essential for GH’s diverse physiological actions, including promoting lipolysis, stimulating tissue repair, and mediating the production of Insulin-like Growth Factor-1 (IGF-1) in the liver. The amplitude and frequency of these pulses are tightly regulated and naturally diminish with advancing age, contributing to the clinical phenotype of somatopause.
