  • Fluoride-induced developmental disorders and iodine deficiency disorders as examples of developmental disorders due to disturbed thyroid hormone metabolism.

    Both exposure to fluoride and iodine deficiency during early development can lead to disturbed thyroid hormone metabolism and produce the same spectrum of developmental disorders including short stature, bone deformities, cognitive impairment, delayed dental eruption, and dental fluorosis. The levels of creatinine-adjusted urinary fluoride experienced by pregnant women in areas

  • Fluoride caused thyroid endocrine disruption in male zebrafish (Danio rerio)

    Highlights Fluoride inhibited the growth of male zebrafish. Fluoride injured the histological structure of thyroid in male zebrafish. Fluoride changed T3 and T4 levels, and genes transcriptions involved in HPT axis. Excessive fluoride in natural water ecosystem has the potential to detrimentally affect thyroid endocrine system, but little is known

    The thyroid 131I consumption, the hypophyseal thyrotropic hormone content and the blood serum total thyroxin and triiodothyronine concentrations were studied in equal groups of healthy humans and donors, living in two cities with an enhanced or decreased fluorine content in drinking water. Iodine deficiency and adaptive amplification of the hypophyseal-thyroid

    The present study was undertaken to investigate the various health problems caused by water-borne fluoride in endemic villages of Mehsana and Banaskantha districts of Gujarat. The study revealed high levels of fluoride in serum samples of the villagers. Mottling of teeth and skeletal complications were common. Intake of fluoride caused

  • 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

  • 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.

  • The Relationship Between Fluoride Exposure & Goitre in South Africa

    As a general rule simple goitre, irrespective of the cause, can be very, or fairly, satisfactorily combated by an adequate increase in man's daily iodine intake, except when the enlargement of the gland is due to the ingestion of excessive amounts of fluorine. The only correct solution to fluorine-induced endemic goitre is the removal of this element from the drinking water.

  • Fluoride's Impact on Thyroid Hormones

    Up through the 1950s, doctors in Europe and South America prescribed fluoride for this purpose in patients with hyperthyroidism. (Merck Index 1968). Fluoride was selected as a thyroid suppressant based on findings dating back to the mid-19th century that fluoride is a goitrogen (a substance that can cause goiter). When used as

  • 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.
