Growth Hormone Secretion Kinetics

Meaning

Growth Hormone Secretion Kinetics refers to the quantitative study of the rate, pattern, and amplitude of Growth Hormone (GH) release from the anterior pituitary gland into the circulation over time. GH secretion is characteristically pulsatile, with bursts occurring throughout the day, often peaking during deep sleep. Understanding these kinetics is essential for diagnosing GH deficiency or excess, as a single random measurement is insufficient to capture the hormone’s true functional status. This precise analysis informs therapeutic strategies, particularly those involving GH replacement or the use of secretagogues.
