Growth Hormone Axis

Meaning

The Growth Hormone Axis, scientifically known as the somatotropic axis, is a complex neuroendocrine feedback loop that tightly regulates the production and action of growth hormone (GH) throughout the body. This axis is essential for linear growth in childhood, maintaining healthy body composition, bone density, and metabolic function across the lifespan. Dysfunction within this system can lead to significant clinical issues, ranging from growth failure to adult GH deficiency. The proper functioning of this axis is central to metabolic and somatic health.
