  • Fluoride and the Thyroid Gland

    EDITORIAL: In 1854 Maument (1) administered to a dog from 20 to 120 mg sodium fluoride daily for four months. He observed an enlargement of the neck which he interpreted as a goiter. Ever since then conflicting data concerning the action of fluoride on the thyroid gland have appeared in the

  • Fluorine and the Thyroid Gland: A Review of the Literature.

    The increasing use of fluoride for prevention of dental caries poses the problem as to whether this halogen has antagonistic properties towards iodine, whereby it could hamper the success of iodine prophylaxis of endemic goitre. Review of the literature shows that some authors have found an inhibition by fluoride of

    In 26 adolescents between 13--15 years of age living in a region with increased fluoride concentration in drinking water (3 ppm = 3 mg NaF/l) bone density-measurements by an I-125 profile scanner as well as measurements of thyroid function by means of numerous in vitro tests (T3U, T4, FT4-Index, RIA-T3,

  • Fluorine in the aetiology of endemic goitre

    MANY different factors leading to relative or absolute deficiency of iodine may cause changes in the thyroid gland. May (1935) found that the administration of fluorine to rats produced hypoplasia of the thyroid epithelium with altered staining reaction of the colloid. Having experimented with over 800 patients, he advocated internal

  • Fluoride Exposure Aggravates the Impact of Iodine Deficiency

    A consistent body of animal and human research shows that fluoride exposure worsens the impact of an iodine deficiency. Iodine is the basic building block of the T3 and T4 hormones and thus an adequate iodine intake is essential for the proper functioning of the thyroid gland. When iodine intake is inadequate during infancy and

  • Is fluoride-induced hyperthyroidism a cause of psychosis among East African immigrants to Scandinavia?

    When people with a compensated fluoride-induced hypothyroidism move to a low-fluoride area, the fluoride-induced inhibition of the production of thyroid hormones ceases. In Scandinavia, the dietary intake of iodine is usually quite high due to iodized table salt and easy access to marine fish. Under these conditions, the elevated capacity for production of thyroid hormones may result in hyperthyroidism.

  • Fluoride Aggravates Thyroid Damage Caused by Excess Iodine Intake

    Chinese researchers have found that the combination of excess fluoride with excess iodine caused greater reductions in IQ, or greater increases in goitre than either scenario by itself.

  • Fluoride & Goiter

    Goitre (aka goiter) is an enlargement of the thyroid gland that in some cases can produce visible swelling in the neck. The main cause of goitre is iodine deficiency. Goitre can also be caused by other things, including hypothyroidism and substances that cause goitre (goitrogens). Since as far back as the

  • Fluoride, Water Hardness, and Endemic Goitre

    Variations in goitre prevalence were found to correlate closely with the fluoride content (p=0-74; P<0-01) and with the hardness (p=0.77; P<0-01) of the water in each village. The effects of fluoride and water hardness seem to be independent.
