Question

which of the following conditions results from hyposecretion of the thyroid gland in an adult?
a myxedema
b ketoacidosis
c tetany
d pheochromocytoma

Explanation:

• Myxedema: Hyposecretion (under - secretion) of thyroid hormones in adults leads to myxedema. It is characterized by symptoms such as swelling (especially of the face), fatigue, and slowed metabolism.
• Ketoacidosis: This is mainly associated with diabetes mellitus (usually type 1), where there is a deficiency of insulin, leading to the accumulation of ketone bodies in the blood. It is not related to thyroid gland hyposecretion.
• Tetany: Tetany is often caused by low levels of calcium in the blood. It can be due to problems with the parathyroid gland (which regulates calcium levels) or vitamin D deficiency, not thyroid gland hyposecretion.
• Pheochromocytoma: This is a tumor of the adrenal medulla that causes excessive secretion of catecholamines (such as epinephrine and norepinephrine). It is not related to the thyroid gland.

Answer:

A. myxedema
