What does somatostatin primarily regulate?

Somatostatin primarily regulates growth hormone, which is produced by the pituitary gland. This hormone plays a critical role in growth, metabolism, and overall bodily function. Somatostatin acts as an inhibitory hormone, meaning it suppresses the secretion of growth hormone, which helps to maintain balanced hormone levels in the body. When somatostatin is released, it decreases the production and release of growth hormone, contributing to homeostasis.

While somatostatin can have a secondary effect on insulin levels by inhibiting its release, its primary regulatory function is related to growth hormone.
