Question

Quizplus · Accepted Answer

When GH hypersecretion begins in adulthood, it is more likely to cause acromegaly. Acromegaly is characterized by enlargement of the bones of the face, jaw, hands, and feet, as well as soft tissue swelling, and is caused by excessive GH production after the epiphyseal plates have closed. In contrast, gigantism occurs when GH hypersecretion begins in childhood before the closure of the epiphyseal plates, resulting in increased linear growth. Myxedema, Graves disease, Cushing syndrome, and goiter are not associated with GH hypersecretion.
