what is the stimulus for release of growth hormone?

The primary stimulus for the release of growth hormone (GH) is growth hormone-releasing hormone (GHRH) produced by the hypothalamus. Additionally, factors such as sleep, exercise, stress, and low blood sugar levels can also stimulate GH release. Conversely, somatostatin inhibits its release. Overall, the regulation of GH is a complex interplay of various hormonal signals and physiological conditions.
