Answer:
hyposecretion of the thyroid (hypothyroidism)
Step-by-step explanation:
Hypothyroidism is a condition in which the thyroid gland is unable to secrete enough thyroid hormone. The Thyroid hormone functions in increasing the metabolic rate of the body.
A low production of thyroid hormone would result in a condition known as hypothyroidism, which presents symptoms such as constipation, dry skin, lethargy etc, as body metabolism is reduced.
