Chelation refers to the use of a substance that helps remove heavy metals or toxic substances from the body. Substances used in Chelation IV Therapy are medications called EDTA, DMPS, DMSA, or Vitamin C. The word chelate means “claw”. The substance claw or grabs onto the offending toxin and pulls it out of the body. Chelation Therapy can be done orally by mouth, or intravenously by IV.

Licensed medical doctors who are trained in Chelation Therapy under a governing board are permitted to do this therapy. EDTA has been approved by the Health Protection Branch, and Health and Welfare Canada , as being safe for patients. It is used to treat cardiovascular disease and peripheral vascular disease.

Does it have any side effects?
If treatment follows the protocol laid down by the American College for the Advancement of Medicine, Chelation IV Therapy is relatively safe. Reactions to EDTA (a synthetic amino acid, ethylene diamine tetra-acetic acid), or added vitamins occurs infrequently. Inflammation at the IV site can occur as any type of IV. EDTA can reduce the amount of insulin needed to treat diabetics. A temporary drop in blood calcium may occur. People with heart failure are monitored closely to avoid excess fluid. The kidneys are not negatively affected if treatment is given according to the prescribed protocol. Chelation Therapy must not be given to pregnant women or to those with severe kidney damage. Almost all EDTA is cleared from the body within 24 hours.

How is Heavy Metal exposure assessed in the body?
A Hair Mineral Analysis can be done by a special laboratory to determine the amount of heavy metals excreted into the hair. Electro-Dermal Screening can often indicated that the body b

What is the CHELATION CHALLENGE TEST for Heavy Metals?
To determine your heavy metal load, DMPS and /or EDTA meds are given intravenously to challenge that load. This is then followed by a 24 hour urine collection to measure heavy metal excretion.

How is EDTA given?
After careful assessment, including a detailed history, physical examination, and laboratory investigation, EDTA IV Therapy is given at a maximum frequency of twice a week, or maybe just once a week. Dosage and frequency are altered according to the patient's assessment and ongoing clinical appraisal. Each treatment takes about 3 hours. It is given with the patient seated in a comfortable chair in which she/he can read, sleep or carry on a conversation. Creatinine, a test kidney function, is monitored regularly to determine the correct dose of EDTA. To maximize the possible benefits of Chelation Therapy, lifestyle modification is essential. This includes stress reduction, proper diet, regular exercise and quitting smoking, combined with taking vitamin and mineral supplements.

How are Heavy Metals chelated?
If the Challenge Test shows elevated heavy metals, a patient may choose to have these levels reduced by Chelation IV Therapy. The type of chelation depends upon the heavy metal present. The most common toxic heavy metals are lead (usually EDTA used), and mercury (usually DMSA or DMPS used). A heavy metal challenge test is repeated after treatment to confirm that the heavy metal load has been reduced with the treatment.

What are the effects of Heavy Metal toxicity?
Studies confirm that heavy metals can directly influence behaviour by impairing mental and neurological function, and altering numerous metabolic body processes. Much of the damage produced by toxic metals stems from the proliferation of oxidative free radicals that they cause.

A free radical is an energetically unbalanced molecule, composed of an unpaired electron that “steals” an electron from another molecule to restore its balance. Current studies indicate that even minute levels of toxic elements have negative health consequences. The impact on health varies from person to person. Nutritional status, sensitivity to certain metals, metabolic rate, the ability to detoxify toxic substances, and the mode and degree of heavy metal exposure all affect how an individual responds. Children and the elderly, whose immune systems are either underdeveloped or compromised, are more vulnerable to toxicity.

Where do these metals come from?
Aluminium, arsenic, cadmium, lead, mercury, and nickel are the most prevalent heavy metals. Breathing heavy metal particles, even at levels well below those considered non-toxic, can have serious health effects. Some people are exposed at work, others suffer from environmental heavy metal exposure. Leaded gasoline has spewed thousands of tons of lead into our atmosphere, gaining entry into our bodies through food and air. Lead paint and pipes, while not in current use, have left their mark. Lead can be found in our water, and commonly found in cosmetics or skin care products. It is estimated that most of us have a body lead burden as much as 500 times that of our forefathers. Mercury is a common industrial waste in water and fish, and is absorbed from our mercury amalgam fillings in our teeth. Cadmium comes from tobacco, arsenic from industrial pollution, and so the list goes on.
