How Toxic are Metals in the Body?

Vanita Dahia

Toxicity of heavy metals can be damaging to health. Heavy metals are naturally occurring elements found in multiple industrial, domestic, agricultural, medical, and technological applications. Toxic levels of metals may be potentially harmful to the body affecting neurological, endocrine, metabolic and immune systems.

Their toxicity depends on several factors including the dose, route of exposure, and chemical species, as well as the age, gender, genetics, and nutritional status of exposed individuals. Because of their high degree of toxicity, arsenic, cadmium, chromium, lead, and mercury rank among the priority metals that are of public health significance. They are classified as human carcinogens (known or probable) according to the Environmental Protection Agency and the International Agency for Research on Cancer.

High levels lead to an increase in Reactive Oxygen Species (ROS) that damage proteins, lipids and DNA. They also form tight bonds with the essential element selenium, reducing its bioavailability for enzymes essential for thyroid hormone synthesis and activation.

Some metals are much more toxic than others. The form of a metal may be more harmful such as an organic versus an inorganic metal compound. How a person is exposed can influence the amount of metal absorbed and the part(s) of the body that are affected. For example, a metal that does little when it is held in someone’s hand, or is only moderately harmful and poorly absorbed when swallowed, may be much more toxic and cause severe lung damage when its vapours are inhaled.

Where do we get heavy metal exposure from?


What does it feel like to have a heavy Metal Toxicity?


  • Chronic pain and fatigue
  • Brain fog – state of forgetfulness and confusion
  • Chronic infections such as Candida
  • Gastrointestinal complaints, such as diarrhoea, constipation, bloating, gas, and indigestion
  • Food allergies
  • Dizziness
  • Migraines and/or headaches
  • Mood swings, depression, and/or anxiety
  • Nervous system malfunctions – burning extremities, numbness, tingling, paralysis, and/or an electrifying feeling throughout the body

In the world of increasing metal exposure although chelation therapy is an important tool in fighting metal storage disorders yet lack of larger clinical trials still offers controversy on its clinical therapeutic benefits.

Employing combination therapy with more than one chelating agent and or prescribing antioxidants or nutraceuticals should be more seriously considered as crucial recommendations of chelation therapy.

Testing for Metal Toxicity


Heavy metal testing is usually tested with essential minerals in one of many samples. Hair metal and mineral analysis is easy, convenient and relatively inexpensive, and represents storage of metals . Heavy metals can also be measured in a urine, blood red cell, faecal or saliva sample.
