Functional state of thyroid under extended exposure to fluorides

The issue of specific effect of fluorine on the thyroid in humans remains debatable. There is no doubt, however, that cases of experimental fluorosis are characterized by specific toxicity of fluorine to the thyroid. The hypoactivity of thyroid epithelium is observed, the destructive changes in the follicular cells increasing with the

The effects of excessive fluoride intake

A survey undertaken in areas of Tanzania where the water has a very high fluoride content showed mottling of the teeth. Some skeletal fluorotic changes were found in some older people. The problem of reducing the fluoride content of the water to acceptable levels is discussed.

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 & 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

Fluorine in the Aetiology of Endemic Goitre

The distribution of endemic goitre in the Punjab and in England is related to the geological distribution of fluorine and to the distribution of human dental fluorosis (mottled enamel). Inquiry showed the presence of dental fluorosis among school-children in two areas of Somerset where two previous observers had recorded a high incidence of goitre, and the absence of dental fluorosis in an adjoining area selected as control where endemic goitre was absent.

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.

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
