What is the Origin of Supra-Physiological GH Levels?

The term combines the Latin prefix 'supra,' meaning "above," with 'physiological,' denoting normal biological function, and 'GH Levels,' indicating the concentration of Growth Hormone. This descriptive terminology is used clinically to distinguish between therapeutic replacement doses and levels that carry a significant risk of adverse effects. Its clinical importance is rooted in the management of both GH deficiency and GH excess.

What is the Mechanism of Supra-Physiological GH Levels?

Excess circulating GH hyper-stimulates the Growth Hormone Receptor, leading to a profound increase in the hepatic production and systemic concentration of Insulin-like Growth Factor 1 (IGF-1). This robust signaling drives widespread anabolic effects but also induces chronic metabolic stress, notably promoting insulin resistance and altering lipid metabolism. Prolonged exposure to supra-physiological levels risks serious adverse effects, including cardiomegaly, arthropathy, and the diabetogenic effect, necessitating careful endocrine monitoring.

Supra-Physiological GH Levels

Meaning

Supra-Physiological GH Levels refer to concentrations of Growth Hormone (GH) in the systemic circulation that are significantly in excess of the normal, pulsatile, and age-appropriate levels naturally produced by the pituitary gland. This state of hormonal excess is typically the result of exogenous administration, often in non-clinical settings, or due to a pathological condition such as a pituitary adenoma causing acromegaly. These elevated levels exceed the body’s natural set point for growth and metabolism.
