Final answer:
Excess production of growth hormone (GH) prior to puberty can lead to a condition called gigantism, which is characterized by abnormally long limbs and tall stature.
Step-by-step explanation:
The hormonal disorder that develops from excess production of growth hormone (GH) before puberty is known as gigantism. Dysfunction of the endocrine system's regulation of growth hormone can lead to several disorders. In the case of children, when there is hypersecretion of GH, often due to a pituitary gland tumor, it can result in gigantism, characterized by abnormally long limbs and tall stature. Individuals with gigantism may grow to be over eight feet tall. In contrast, adults with excess GH after their growth plates have closed can develop acromegaly, which is the enlargement of bones in the face, hands, and feet.
