What happens if a child gets GH treatment (growth hormone), without having GH deficiency?

Question

Lets assume a kid is bad diagnosed as having GH deficiency, but actually the child is just short for parental reasons... the child starts the GH treatment. What is going to happen? Will it improve the adult height of the child?

Answer 1

Excessive GH levels lead to gigantism, with increase in height and body weight -- these individuals also frequently have glucose intolerance and hyperinsulinism (both as effects of GH). They also have organomegaly (any or all viscera being hypertrophic), and they are more susceptible to infections.

If given after the growth plates have fused, acromegaly may be seen, primarily manifest as a thickened calvarium and enlarged frontal sinuses, causing the prominent brow often associated with anabolic steroid and GH use. Acromegaly is also characterized most by enlargement of the hands and feet (which may cause carpel tunnel syndrome), and laryngeal growth, which deepens the voice.
