Question

Hypothyroidism is caused by the deficiency of

• A. Glucocorticoid
• B. Vitamin B-12
• C. Adrenalin
• D. Thyroxine

Answer 1

The Correct Option is D

Hypothyroidism is a condition that occurs when the thyroid gland does not produce enough thyroid hormones, primarily thyroxine. Thyroxine is essential for regulating metabolism and other bodily functions. Deficiency of thyroxine leads to a slower metabolism and various symptoms associated with hypothyroidism.

The correct option is (D): Thyroxine

Answer 2

Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormones, particularly **thyroxine** (T4). Thyroxine plays a crucial role in regulating metabolism, growth, and development. A deficiency of thyroxine leads to symptoms such as fatigue, weight gain, and cold intolerance, which are characteristic of hypothyroidism.  

Glucocorticoid: These are steroid hormones that regulate metabolism and immune response, but their deficiency is associated with conditions like Addison's disease, not hypothyroidism.
Vitamin B-12: Deficiency in Vitamin B-12 leads to anemia and neurological issues, not hypothyroidism.
Adrenalin: Adrenaline (epinephrine) is produced by the adrenal glands and is involved in the "fight or flight" response. Its deficiency causes other symptoms, but not hypothyroidism.

Thus, thyroxine is the correct hormone linked to hypothyroidism.
