Iodine high hyperthyroidism symptom?

summary

Iodine is closely related to thyroid gland; The former is the raw material for the synthesis of thyroid hormone, and the daily iodine requirement of adults is about 70 μ g. The number of adolescents ranged from 150 to 200 μ g。 In a certain dose range, the synthesis of thyroid hormone increases with the increase of iodine supply, but if the iodine supply exceeds a certain limit (normal people 5mg / D, hyperthyroidism patients 2mg / D), the symptoms of hyperthyroidism? Next, I'd like to share my views with you.

Iodine high hyperthyroidism symptom?

The cardiovascular symptoms and signs were obvious, and the serum anti thyroid antibody was negative. Thyroid scanning can find the existence of "hot area". The iodine uptake rate of thyroid was lower than 3% in 24 hours. Because the normal range of urinary iodine is large, the determination of urinary iodine is not helpful for diagnosis.

(in iodine deficiency areas, most patients with IIH have thyroid nodules, 15% - 30% have small or no goiter, and some patients have no nodules). The condition is relatively mild, and there is no tenderness in the thyroid gland. Thyroid examination shows nodular goiter or single nodules, generally without exophthalmos, and there are few vascular murmurs and tremors in the thyroid gland,

The clinical manifestation of iodine hyperthyroidism is similar to Graves' disease, but the former is older, mostly occurs in the elderly, less in children (it has been reported that none of 50000 children receiving iodine treatment has IIH), and the ratio of male to female is 1 ∶ 6-1 ∶ 10, which is similar to Graves' disease,

matters needing attention

The demand for non iodized salt should be met, that is, non iodized salt should be purchased for patients with other thyroid diseases or other patients who are not suitable for iodized salt, and there should be shops selling non iodized salt in each community (this is clearly stipulated in the salt iodization regulations).
