What too much and too little growth hormone taught about the hormone

Published 24 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Pierre Marie described acromegaly in 1886: enlargement of hands, feet and facial bones in adults, later traced to pituitary tumours secreting growth hormone. Deficiency in childhood produces proportionate short stature; Laron described in 1966 a form with high growth hormone and low IGF-1 caused by a defective receptor. Between them these states define what the hormone does: it drives longitudinal growth before the growth plates close, and in adults it shifts body composition toward lean mass, alters glucose handling and affects connective tissue.

Excess

In adults the long bones cannot lengthen, so excess hormone thickens bone and soft tissue instead: the acral enlargement that named the condition. It also raises IGF-1, causes insulin resistance, enlarges organs and increases cardiovascular and joint disease. In children the same excess produces gigantism. The condition is treated by removing the tumour or by blocking the hormone with a somatostatin analogue or the receptor antagonist pegvisomant.

Acromegaly is the clearest evidence that the hormone has effects beyond growth throughout adult life.

Deficiency

Children without the hormone grow slowly and reach a short adult height; this was the condition Raben treated in 1958. Adults with deficiency, often after pituitary surgery, show reduced lean mass, increased fat, low bone density and reduced exercise capacity. Laron syndrome, with a defective receptor, shows the same picture despite high hormone levels and is the human proof that the receptor and IGF-1 are necessary.

Individuals with Laron syndrome have been reported to have very low rates of cancer and diabetes, an observation that has driven research into the axis and ageing.

What the two ends establish

The hormone is necessary for normal growth and has lifelong metabolic actions; both deficit and excess are harmful; and the receptor and IGF-1 lie on the path. This is physiology, not a description of any use of the material.
