Symptoms of Mercury Poisoning

In chronic mercury poisoning, digestive and nervous symptoms predominate.

Early signs include slight digestive disorders, intermittent tremors, and neurotic disorders.

Gingivitis (gum inflammation/disease) is the most common gastrointestinal disorder encountered in mercury poisoning.

Ulcerous stomatitis, that is, inflammation and/or ulceration emanating from the corners of the mouth, is much less common and is normally found in persons already suffering from gingivitis who have accidentally inhaled mercury vapors.

Other gastrointestinal disorders encountered in mercury toxicity include gastritis and gastroduodenitis.

Nervous system involvement may include clinical signs of fine intention tremor and Parkinsonism with tremor at rest.

The most frequently encountered symptoms resemble those associated with Multiple Sclerosis.

Tremor usually disappears during sleep, although sudden generalized cramps or contractions may occur.

Tremors typically begin with a subtle trembling of the fingers; this later affects the hand, forearm, facial muscles, tongue, and larynx and eventually reaches the lower limbs.

With Mercury toxicity in its most acute form, tremors may invade all the voluntary muscles and be continuous.

Comparing the above with other heavy metal poisoning symptoms such as Lead, Arsenic, Cadmium and Zinc to name a few, and of course, depending on the symptoms an individual with Multiple Sclerosis has experienced, could easily lead to an erroneous belief that one particular heavy metal has to be the significant factor in Multiple Sclerosis.

An example of a known heavy metal exposure other than mercury dental amalgam causing neurological deficit would be that of lead lined water pipes or paint with excessive lead content.

Having said that, there have been studies done which show a trend towards dental amalgam fillings and the occurrence of Multiple Sclerosis.

This could point the way towards mercury toxicicity since this metal does indeed have significant neurotoxic effects, or it could simply be a reflection of the cravings an MS'r has for carbohydrates and sweets and the subsequent effect all the extra sugar has on teeth and the requirement for more dental fillings.




Multiple Sclerosis

The risk of contracting Multiple Sclerosis if your mother has the disease is approx 1 in 50.

Life Expectancy

Life expectancy for people who have multiple sclerosis is growing longer with every passing year, particularly with the advancement of medical science, new drugs and better care and understanding of the disease.... Read More
