What is the Origin of Growth Hormone Suppression?

The term is a compound of "growth hormone," the key peptide hormone for somatic growth and metabolism, and "suppression," derived from the Latin supprimere (to press down). In endocrinology, it refers to the inhibitory control mechanisms that tightly regulate the pulsatile release of GH from the somatotroph cells. Understanding the factors that cause GH suppression is essential for diagnosing disorders of the somatotropic axis.

What is the Mechanism of Growth Hormone Suppression?

The primary inhibitory mechanism is the release of somatostatin from the hypothalamus, which acts directly on the pituitary somatotrophs to block GH secretion. Additionally, circulating IGF-1, whose production is stimulated by GH, completes a long-loop negative feedback by inhibiting GH release at the pituitary and stimulating somatostatin release at the hypothalamus. Nutritional factors, like hyperglycemia and hyperinsulinemia, also acutely suppress GH secretion via central and peripheral signaling pathways.

Growth Hormone Suppression

Meaning

Growth hormone suppression is the physiological or pharmacological reduction in the secretion of Growth Hormone (GH) from the anterior pituitary gland. Physiologically, this can be a normal negative feedback response, often mediated by elevated levels of Insulin-like Growth Factor 1 (IGF-1). Clinically, GH suppression is sometimes therapeutically induced to manage conditions characterized by excessive GH, such as acromegaly, or it may occur pathologically due to chronic disease or specific medications.
