Question 5: Causes of Hypothyroidism

Question 5: Causes of Hypothyroidism

Hypothyroidism is the low secretion of thyroid hormones by the thyroid gland. Such low secretion can be due to disorders of the thyroid gland, pituitary gland, or hypothalamus. The disorders of the thyroid gland include the use of amiodarone, iodine deficiency, thyroidectomy, thyroid radiation, and Hashimoto’s thyroiditis (Chiovato et al., 2019). These conditions contribute to the majority of hypothyroidism cases, although hypopituitarism and deficiency of hypothalamus hormones (McDermott, 2020).
