Mercury, the Thyroid and Diabetes

Mercury is a neurotoxin and perinatal exposure can lead to impairment in neurological development. Normal thyroid function is also necessary for normal neurological development and this fact had therefore led investigators to explore the relationship between mercury and the thyroid.  Their studies involving animals has revealed low dose exposure to mercury induces changes in brain deiodinase activities in neonates.

Other research has shown that mercury can also affect glucose transport. The studies found that via a series of enzymatic mechanisms, mercury can contribute to insulin resistance and can therefore, be a factor in pathologies associated with diabetes.

Comment: It is very common to find elevated mercury in patients diagnosed with hypothyroidism.  It is well known that mercury can cross the placental barrier and accumulate in the foetus.  This study shows that not only can mercury directly affect neurological tissues, but even low exposure to mercury can affect thyroid function, which could in turn adversely affect neurological development. HTMA studies would indicate that mercury accumulation could lead to abnormal thyroid function in the adult, as well as affect blood sugar regulation.

Dr Mercola explains more about the toxicity of mercury and how our amalgam fillings constantly leak this toxic substance.  However, before rushing out to have all amalgam fillings replaced, please arrange a consultation with Dagmar to help prepare your body and assist in safe removal of mercury from your body.

While Australian dentists are still freely using amalgam fillings, other countries have banned the use of this type of dental filling:

  • Denmark, Norway and Sweden have essentially banned amalgams,
  • There are 5,636 hospitals in developing countries that are committed to or already mercury-free. The majority of these are in the Philippines, India and Argentina,
  • Canada advised dentists to stop placing amalgam in children and pregnant women in 1996.

Mercury from dental offices is actually the largest source of mercury found in wastewater. According to an article by Michael Bender (co-founder of the Mercury Policy Project), at least 40 percent of mercury flowing into municipal water treatment plants comes from dentist offices! And urban water treatment plants are not set up to remove it, so eventually this dental mercury will end up in the fish on your dinner plate.

The risk doesn’t end there, however.

Mercury fillings in the teeth of someone who dies actually pose a risk to the living. Emissions from the combustion of mercury fillings during cremation are a significant contaminator of air, waterways, soil, wildlife and food. Seven to nine metric tons of mercury per year escapes into the atmosphere during cremations, and it is estimated that, left unchecked, crematoria will be the largest single cause of mercury pollution by 2020. Sweden now mandates that all mercury fillings be removed prior to cremation for this very reason.
