The Effects of Iodine Excess

2017
Iodine is a necessary micronutrient and essential for the synthesis of the thyroid hormones. Iodine exposure may also occur as a result from iodine fortifications programs (through salt iodization, fortification of foods, or other routes), medications, dietary supplements, topical iodine antiseptics, radiographic iodinated contrast media, and other ...

Properties of amylose-iodine complexes prepared in the presence of excess iodine

Carbohydrate Research, 1982
Abstract A potentiometric-titration procedure, in which samples are always exposed to an excess of I2-KI has been developed for measuring iodine-binding capacity of starches. Binding capacity of amylose under these conditions is ∼30% as opposed to 20% by conventional potentiometric titration.

Iodine excess and thyroid autoimmunity.

Journal of endocrinological investigation, 2004
Epidemiological studies, as well as animal models, indicate that iodine might be an immunogenic agent for the thyroid gland, at least in subjects predisposed to thyroid autoimmunity. This review presents data, either epidemiological or experimental, obtained in different conditions: constant and stable iodine status, either deficient, sufficient or ...

TWO TYPES: Hyperthyroidism may develop in around 10% of patients in excess iodine. It may reveal an undetected pretoxic thyroid disease (type I) or have been induced by excess iodine in previously normal thyroid gland or in an euthyroid goiter (type II). IODINE EXCESSE REVEALING THYROTOXICOSIS: In the former situation, symptoms appear shortly after the

[Iodine excess and thyroid dysfunction].

La Revue du praticien, 2005
Hypothyroidism or hyperthyroidism may develop during iodine excess. Hypothyroidism occurs mostly in newborns or in elderly patients with underlying autoimmune thyroiditis and is treated by substitutive doses of thyroxine. Hyperthyroidism is of two types.

Presse medicale (Paris, France : 1983), 2002
WOLFF-CHAIKOFF'S EFFECT: The thyroid gland has a capacity to reduce thyroid hormone production in the presence of excess iodine by reducing the organification of the iodine. This Wolff-Chaikoff effect is observed after 48 hours and protects the organism from excessive synthesis of the thyroid hormones.

[Iodine excess induced thyroid dysfunction].

Revue medicale suisse, 2016
The principle sources of iodine overload, amiodarone and radiologic contrast media, are frequently used in modern medicine. The thyroid gland exerts a protective effect against iodine excess by suppressing iodine internalization into the thyrocyte and iodine organification, the Wolff-Chaikoff effect.

Thyroid Dysfunction Induced by Excess Iodine

1993
Although this conference is primarily concerned with iodine deficiency and its adverse effects on thyroid function and health worldwide, excess iodine ingestion, especially in pharmacologic quantities, may also adversely affect thyroid function, especially in patients with underlying thyroid disease.
