Iodine Excess and Hyperthyroidism
Thyroid, 2001 150 microg iodine are daily required for thyroid hormone synthesis. The thyroid gland has intrinsic mechanisms that maintain normal thyroid function even in the presence of iodine excess. Large quantities of iodide are present in drugs, antiseptics, contrast media and food preservatives. Iodine induced hyperthyroidism is frequently observed in patients

, 2011 Abstract Iodine is an essential substrate for the biosynthesis of thyroid hormone because both thyroxine (T4) and triiodothyronine (T3) contain iodine. An adequate supply of dietary iodine is therefore necessary for the maintenance of normal thyroid function.

Several mechanisms are involved in the maintenance of normal thyroid hormone secretion, even when iodine intake exceeds physiologic needs by a factor of 100. The sodium-iodide symporter system contributes most to this stability. Faced with an iodine excess, it throttles the transport of iodide into the thyroid cells, the rate-limiting step of hormone ...

Excessive iodine intake in schoolchildren
European Journal of Nutrition, 2011Inadequate iodine intake may result in iodine deficiency disorders (IDD). Thus, for more than 50 years, policies for the regulation of salt fortification with iodine have existed in Brazil. In 2003, a study on 6-14-year-old schoolchildren from regions of the state of São Paulo showed a median urinary iodine concentration of 360 μg/L.

Excessive iodine in iodized household salt in Nepal
Annals of the New York Academy of Sciences, 2022Abstract Iodine is an essential trace element required for the regulation of physiological processes involving the thyroid gland. However, inadequate and excessive intake of iodine are responsible for health problems, such as iodine deficiency disorders, hypothyroidism, hyperthyroidism, thyroiditis, thyroid papillary cancer, and ...

This study aimed to compare the effect of excess iodine and herbs with excess iodine on treating iodine deficiency-induced goiter from the perspective of oxidative stress and to measure selenium values in Chinese herbs. One hundred twenty 4-week-old Wistar rats were selected and randomly divided into four groups after inducing iodine-deficiency goiter:

Kinetics of acute and chronic iodine excess
Experimental and Clinical Endocrinology & Diabetes, 2009Iodine plays an important role in thyroid physiology resulting from its importance as a requisite substrate for the synthesis of thyroid hormones and from its action as a regulator of thyroid function. Following intestinal absorption, inorganic iodide is largely confined to the extracellular fluid.

Abstract Iodine is a micronutrient that is required for thyroid hormone synthesis. The iodide cycle in thyroid hormone synthesis consists of a series of transport, oxidation, organification, and binding/coupling steps in thyroid follicular cells.

Iodine Excess and Thyroid Autoimmunity
1993Goiter and hypothyroidism due to iodine deficiency are major world health problem. Intake of excess iodine, either in food, water or drugs, may also result in disturbances of thyroid function and goiter1,2. Clinical data as well as animal experiences have shown a sharp rise in the incidence of autoimmune thyroiditis when iodine consumption was ...
