Quick Answer: Does Iodine Suppress Thyroid Function?

How does iodine affect the thyroid?

When blood levels of TSH rise, the thyroid gland uses iodine to make thyroid hormones.

However, when your body is low in iodine, it can’t make enough of them ( 9 ).

To compensate, the thyroid gland works harder to try to make more.

This causes the cells to grow and multiply, eventually leading to a goiter..

Do you pee out excess iodine?

When iodide enters the circulation, the thyroid gland concentrates it in appropriate amounts for thyroid hormone synthesis and most of the remaining amount is excreted in the urine [2]. The iodine-replete healthy adult has about 15–20 mg of iodine, 70%–80% of which is contained in the thyroid [6].

Does iodine help thyroid?

Iodine is an element that is needed for the production of thyroid hormone. The body does not make iodine, so it is an essential part of your diet. Iodine is found in various foods (see Table 1). If you do not have enough iodine in your body, you cannot make enough thyroid hormone.

Can excess iodine cause hypothyroidism?

It may cause the thyroid gland to become overactive and produce excess thyroid hormones (hyperthyroidism), particularly in people who used to consume too little iodine. However, sometimes excess iodine can decrease production of thyroid hormones (causing hypothyroidism).

How does iodine inhibit thyroid hormone release?

Effects of Iodine Load A normal thyroid gland responds to iodine load through an intrinsic autoregulatory mechanism, which acutely blocks thyroid hormone synthesis (Wolff-Chaikoff effect) and causes an increase in serum TSH concentration.

How long does iodine take to improve thyroid?

Under normal circumstances, plasma iodine has a half-life of approximately 10 hours, but this is shortened if the thyroid is overactive, as in iodine deficiency or hyperthyroidism. The mean daily turnover of iodine by the thyroid is approximately 60-95 µg in adults in iodine-sufficient areas.
