GH-IGF-1 Feedback Loop

GH stimulates hepatic IGF-1; IGF-1 feeds back to suppress GH at hypothalamus and pituitary.

A free, animated gh-igf-1 feedback loop you can read here or embed on any website, from Scrollchart.

Source & accuracy

This gh-igf-1 feedback loop is an editorial illustration built to represent the concept accurately. Where it shows figures, they are typical or representative values chosen to make the relationship clear, not a single underlying dataset. The diagram and its explainer are reviewed and maintained centrally, and updated over time as understanding improves.

How growth hormone and IGF-1 form a loop

Growth hormone (GH) released by the pituitary travels to the liver, where it stimulates production of insulin-like growth factor 1 (IGF-1). Much of GH's growth-promoting effect on tissues is actually mediated by IGF-1 rather than by GH acting directly, which is why the two are usually discussed together.

IGF-1 then acts as the brake. It feeds back on the hypothalamus and pituitary to reduce further GH release, and it also prompts the hypothalamus to release somatostatin, which directly inhibits GH. This negative feedback keeps the axis from running away.

Why the loop runs slowly and steadily

GH is secreted in sharp pulses, but IGF-1 is bound to carrier proteins in the blood and has a much longer half-life, so its level stays comparatively stable across the day. That stability makes IGF-1 a smoother feedback signal and a more reliable blood marker of average GH activity than a single GH measurement.

This is general educational information, not medical advice; evaluation of GH or IGF-1 levels should be carried out by a qualified professional.
