Final answer:
Excessive use of human growth hormone can lead to acromegaly in adults, which causes enlargement of the bones in the face, hands, and feet, and gigantism in children, which results in abnormal overall body growth. Underproduction in children leads to pituitary dwarfism.
Step-by-step explanation:
Conditions Resulting from the Use of Human Growth Hormone
The use of human growth hormone (GH) can lead to certain medical conditions. A condition that can arise from the excessive use or abuse of GH is acromegaly, which primarily affects adults. Acromegaly is marked by the enlargement of bones present in the face, hands, and feet. On the other hand, gigantism can occur if there is an overproduction of GH in children, causing abnormally excessive body growth. Both conditions are due to the disruption of normal endocrine function and balance within the body. It's important to note that while conditions like insomnia and abnormal heart rhythm, diarrhea and dehydration, and decreased liver functioning can arise due to a variety of causes, they are not directly associated with GH use.
Furthermore, pituitary dwarfism or growth hormone deficiency is another serious condition resulting from the underproduction of GH in children, leading to significantly reduced growth and stature, though often with normal intellectual and sexual development.
