Effect of 131I on the anemia of hyperthyroidism

Prevalence and characteristics of anemia associated with thyroid disorders in non-pregnant Saudi women during the childbearing age: A cross-sectional study

“…[14,[20][21][22] To the best of our knowledge, this is the first study to report the prevalence of thyroiditis-induced anemia in non-pregnant females during the childbearing age in Saudi Arabia. The present study showed thyroid abnormalities in 19.6% of the study population and the most common thyroid disorders were subclinical hypothyroidism followed by overt hypothyroidism.…”

“…Although anemia was reported with different types of thyroiditis, it is more common in hypothyroidism compared to hyperthyroidism. [3,7,8,11,14,16] The decreased prevalence of anemia with hyperthyroidism could be explained by the observed increase in erythrocytosis. [8,16] The current study supports the earlier observations as it showed a significant increase in the prevalence of anemia in the overt and occult hypothyroidism groups compared to normal thyroid group.…”

“…[6,7,10] Alternatively, hyperthyroidism is less prevalent with a frequency ranging between 0.5 and 2% in women. [1,3,[10][11][12][13][14][15] Thyroid disorders are associated with hematological abnormalities and anemia is the most prevalent disorder. [6,12,[16][17][18] Early reports have shown a decrease in the number of red blood cells (RBCs) in the peripheral blood of patients after thyroidectomy [19] and anemia has been defined in 20-60% of the patients with hypothyroidism.…”

“…[6,12,[16][17][18] Early reports have shown a decrease in the number of red blood cells (RBCs) in the peripheral blood of patients after thyroidectomy [19] and anemia has been defined in 20-60% of the patients with hypothyroidism. [7,8,16] Although early reports showed that Graves' disease is also associated with hematological disorders, [11,14,15] anemia is not frequently observed in patients with hyperthyroidism, whereas erythrocytosis is common. [8,15,16] Furthermore, it has been found that all hematological parameters return to normal when a euthyroid state is achieved.…”

“…[8,15,16] Furthermore, it has been found that all hematological parameters return to normal when a euthyroid state is achieved. [14,[20][21][22][23] Females are more prone to the development of thyroid disorders and/or anemia, especially during the reproductive age and pregnancy. [2,3,6,7,12] Little is known about the incidence of thyroid disorders and their associated types of anemia in Saudi Arabia.…”
