Hypothyroidism Epidemiology

Rodrigo Arrangoiz MS, MD, FACS, FSSO

Hypothyroidism results from insufficient production and secretion of thyroid hormones.

  • This is most commonly due to disturbance within the thyroid gland itself, (primary hypothyroidism) or within the hypothalamic-pituitary-thyroid axis (secondary hypothyroidism).

Causes of primary hypothyroidism

1. Associated with goitre

  • Hashimoto’s thyroiditis (chronic lymphocytic thyroiditis)
  • Iodine deficiency
  • Inherited defects of biosynthesis
  • Drug induced (amiodarone, lithium, phenylbutazone)
  • Maternal transmission (e.g. anti-thyroid drugs)

2. Not associated with goitre

  • Atrophic thyroiditis
  • Iatrogenic (e.g. radioiodine, surgery, neck irradiation)
  • Congenital anomaly (e.g. thyroid agenesis)

3. Self-limiting

  • Transient thyroiditis
  • Post partum thyroiditis
  • Iatrogenic (overtreatment with anti-thyroid medication)

The prevalence of hypothyroidism is estimated at around 2% of adult women and 0.2% of men, rising to 5% to 10% in women over 65
