Final answer:
Gigantism results from excessive growth hormone production in children, causing them to grow abnormally tall with long limbs, while acromegaly occurs in adults, resulting in enlarged bones of the face, hands, and feet. Both conditions are typically caused by a pituitary gland tumor leading to hypersecretion of GH.
Step-by-step explanation:
The disorder caused by hypersecretion of growth hormones (GH) during childhood is known as gigantism, which leads to excessive growth and abnormally long limbs. In adulthood, overproduction of GH causes acromegaly, characterized by the enlargement of facial structures, hands, and feet. Both conditions can be a result of a tumor in the pituitary gland leading to an overproduction of GH.
Gigantism is the disorder caused by hypersecretion of growth hormones during childhood, and acromegaly is the condition seen in adults.
A balanced production of growth hormone is essential for normal growth and development. Hypersecretion of GH can have different effects depending on the age of onset. In children, it can cause gigantism, resulting in a giant-like stature with very long arms and legs. In contrast, adults with excess GH production develop acromegaly. This condition is particularly notable for causing enlargement of bones in the face, hands, and feet, areas of the body that can still grow post-maturity. These disorders can significantly affect a person's appearance and health. Treatment commonly involves addressing the underlying cause, such as removing the pituitary tumor responsible for the excessive hormone production.
