Which condition is characterized by enlargement of the hands and feet due to excessive secretion of the growth hormone after puberty?

a. acromegaly

b. hyperpituitarism

c. gigantism

The answer is A: Acromegaly

Explanation:

Acromegaly is a hormonal disorder that develops when the pituitary gland produces too much growth hormone during adulthood resulting in an increase in bone size, including those of the hands, feet and face. It usually affects middle aged adults, though it can develop at any age. In children who are still growing, too much growth hormone can cause a condition called gigantism. These children have exaggerated bone growth and an abnormal increase in height.

Acromegaly.

Explanation:

Hormones are the chemical substances that regulates the growth and proper functioning of the organisms. The pituitary gland is known as the master gland of the body.

Growth hormones regulate the proper functioning of the body. The deficiency of growth hormone causes dwarfism and its over secretion can cause gigantism. The excess secretion of the growth hormone after puberty is known as acromegaly that causes growth of hands and legs.
