Question

Iodine deficiency often results in goitre formation. This occurs due to the hypersecretion of which hormone?

Select one:
a. Thyroid stimulating hormone (TSH)
b. Triiodothyronine (T3)
c. Calcitriol
d. Thyroxine (T4)
e. Thyrotropin releasing hormone (TRH)

Answer 1

a. Thyroid stimulating hormone( TSH)

Step-by-step explanation:

The pituitary gland senses a low thyroid hormone level and secretes more TSH to stimulate the thyroid. This stimulation causes the thyroid to grow, which may produce a goiter. Another common cause of goiter is Graves' disease.Graves' disease is an autoimmune disorder in which antibodies produced by your immune system stimulate your thyroid to produce too much T4. It's the most common cause of hyperthyroidism. Hyperfunctioning thyroid nodules (toxic adenoma, toxic multinodular goiter or Plummer's disease).
