What is the Origin of GH Pulsatility?

The concept was definitively established through meticulous endocrine research that required frequent, often minute-by-minute, blood sampling over 24-hour periods to accurately map the secretion profile of Growth Hormone. This revealed that the traditional single-point blood test was insufficient for assessing GH status, emphasizing the importance of the secretory rhythm. This discovery revolutionized the understanding of the somatotropic axis.

What is the Mechanism of GH Pulsatility?

The pulsatile release is tightly controlled by the reciprocal interplay of two hypothalamic neurohormones: Growth Hormone-Releasing Hormone (GHRH), which stimulates the pulses, and somatostatin, which acts as an inhibitory brake between the pulses. The specific frequency and amplitude of these pulses are essential for the GH receptor's sensitivity in the liver, where it triggers the production of Insulin-like Growth Factor-1 (IGF-1), the primary mediator of GH's anabolic and growth-promoting effects.

GH Pulsatility

Meaning

GH pulsatility refers to the characteristic, non-continuous pattern of Growth Hormone (GH) release from the anterior pituitary gland, which occurs in discrete, high-amplitude bursts or pulses. The secretion is not a steady flow but rather a rhythmic, episodic phenomenon, with the majority of the hormone being released during the night in the deeper stages of sleep. This specific temporal pattern is crucial for GH’s biological effectiveness and proper downstream signaling.
