What are the signs and symptoms of heavy metal poisoning?

Michael T. Murray, ND
Naturopathic Medicine

Early signs of heavy metal poisoning are usually vague and depend on the level of toxicity. Mild cases of toxicity may be associated with headache, fatigue, and impaired ability to think or concentrate. As toxicity increases, so does the severity of signs and symptoms. A person with severe toxicity may also experience muscle pains, indigestion, tremors, constipation, anemia, pallor, dizziness, and poor coordination.

Numerous studies have demonstrated a strong relationship between intelligence, childhood learning disabilities, and body stores of lead, aluminum, cadmium, and mercury. Basically, the higher children's level of heavy metals, the lower their IQ. The same sort of relationship exists with blood pressure, as high blood pressure is also associated with higher levels of lead and other heavy metals. Heavy metals have a very strong affinity for body tissues composed of fat, like the brain, nerves, and kidneys. As a result, heavy metals are almost always linked to disturbances in mood and brain function as well as neurological problems (including multiple sclerosis) and high blood pressure (the kidneys regulate blood pressure).
