The prevalence of overt hypothyroidism in the general population varies between 0.3% and 3.7% in the United States, and between 0.2% and 5.3% in Europe.1-4 The prevalence of hypothyroidism increases with age (>65 years) and is higher among white individuals and women.5 The disorder is nearly 10 times more common in females than in males. On the other hand, subclinical hypothyroidism is more prevalent than overt hypothyroidism in all age groups and can be seen in 4% to 15% of women, especially the elderly.6 Myxedema coma mortality rates with current treatments are between 30% and 60%.6
