Epidemiology Hyperthyroidism

  • Hyperthyroidism in the United States:
    • Occurs in 0.05% to 1.3% of the general population:
      • With the majority of cases consisting of subclinical disease
    • The prevalence of hyperthyroidism:
      • Is approximately 5 to 10 times less than that of hypothyroidism
      • White and Hispanic populations in the United States:
        • Have a slightly higher prevalence of hyperthyroidism than black populations
  • TNG:
    • Is the most frequent cause of thyrotoxicosis:
      • In the elderly
    • It accounts for about 5% to 15% of patients with endogenous hyperthyroidism:
      • But the proportion is:
        • Higher in iodine-deficient geographic regions
    • Changes in the iodine content of salt and in the iodine supplementation of water have been linked to changes in the incidence of TNG:
      • In Switzerland in 1980 and in Spain in 1994:
        • The iodine content of salt was increased, and this was associated with a transient increased incidence of thyrotoxicosis followed by decreased incidence:
          • Mainly the result of reduced TNG incidence
  • Graves Disease:
    • Being the most common cause of thyrotoxicosis in all age groups
    • Graves’ disease accounts for 70% to 80% of endogenous hyperthyroidism
    • The incidence of Graves’ disease is five times higher in females than in males:
      • Occurring generally during women’s reproductive years:
        • Although it may occur at any age
