Furthermore, artificially elevating IGF-1 through methods such as hormone injections is not without danger and should only be considered under strict medical supervision to avoid adverse side effects. Structurally similar to insulin, this compound mediates the effects of growth hormone (GH), translating its signals into tangible tissue growth and repair.

Clinical Measurement and Interpretation Because IGF-1 has a stable half-life compared to pulsatile hormones like GH, it is a reliable biomarker used by medical professionals to diagnose growth disorders. Once GH is secreted, it travels through the bloodstream and binds to receptors on liver cells, triggering a cascade of intracellular events that result in the synthesis and secretion of IGF-1.
Its primary function is to promote the proliferation of cells and inhibit programmed cell death, ensuring the maintenance and repair of tissues. Interpretation of these results requires context, as levels vary based on age, sex, and nutritional status, making it essential to consult with an endocrinologist.
