Frequently asked questions about testing, treatment and prevention

What are 'heavy metals'?

There are many heavy metals in our environment both naturally and from pollution. The term “heavy metal” applies to a group of metals with similar chemical properties. Some of these, including copper, iron and zinc, play important roles in our bodies. Others have no known benefit for health.

Examples of these are lead, which is found in paint in old homes as well as many
other sources; arsenic, which can be found in well water and wood products; and
mercury, which can build up in fish that we eat. At very high levels, most heavy
metals can cause health problems.

How are people exposed to heavy metals?

People may be exposed to small amounts of heavy metals through food, water, air,
and commercial products. People can also be exposed in their workplace, as several
industries use or produce these metals. Each metal is different in where it is found
and how it behaves in our bodies. Exposure alone does not mean that it is causing
any disease or harm.

What is acute heavy metal poisoning?

Acute heavy metal poisoning usually occurs when people are exposed to large
amounts of a metal at one time. For example, swallowing a leaded toy can cause
a large amount of lead exposure all at once. This generally does not occur from
exposures that you are not aware of. Acute exposures are dangerous and can
quickly cause serious health effects or death. Some signs of acute poisoning can be confusion, numbness, nausea and vomiting, and coma.

What are the symptoms of “chronic” heavy metal poisoning?

There is growing evidence that “chronic” or long-term exposure to lower levels of
heavy metals also causes health problems. The symptoms of chronic heavy metal
poisoning can be severe, but are often less obvious and develop much more slowly
over time than the symptoms caused by acute exposure. This is a topic of growing
scientific evidence that still needs more research to clarify all the possible health
effects. Chronic heavy metal poisoning can be challenging for both health care
providers and patients because there are often many more questions than answers.
Many of the symptoms of chronic heavy metal toxicity can include:
True chronic heavy metal poisoning is rare. More often, these same symptoms can be
caused by other health problems not related to a metal exposure at all. It is important
to know that it may not be possible to find the true cause.

How do you know if your symptoms are due to heavy metals instead of
more common causes?

Diagnosing chronic heavy metal poisoning can be challenging for both health care
providers and patients because there often are many more questions than answers.
The bottom line is that diagnosis of chronic heavy metal poisoning relies on having a
known exposure and positive results on approved tests that are specific to each metal.

If I have these symptoms, should I be tested for chronic heavy metal poisoning?

It is generally not recommended to test for chronic heavy metal poisoning unless
directed to by your health care provider based on your symptoms and a known
exposure. Exceptions to this include screening high-risk children for lead poisoning;
and certain occupational settings where specific metals may be present. If you think
you have been exposed to greater than normal amounts of a heavy metal, such as
lead or arsenic, be sure your health care provider is aware of your concern.

How do you test for chronic heavy metal poisoning?

Different heavy metals are best tested for in different ways. Some are tested for in
urine, and some are tested for in blood samples. One single test is not going to give
the best information for all heavy metals.
• Headache;
• Weakness;
• Muscle and joint pains;
• Constipation;
• Feeling tired.

Below is some information about the commercially available ways you may have heard
about to test for heavy metals. Any of these can measure the amount of a given metal
in the sample. The tests do not tell you if the metal is causing health effects. Again,
because heavy metals are all around us, we are all expected to have some in our
body. Whether heavy metals in your body are causing health problems is a different
question, and must be determined in conversation with one of our physicians.

Should I have a hair analysis?

Diagnosis or treatment should not be based on hair analysis alone. Hair is very good at
picking up material such as sweat and dust that can contain many things, including
heavy metals. This makes it hard to tell if a metal is from inside or outside of the body.
Other sources of metals can include hair products such as shampoos, perm products,
bleaches, and hair spray. These will show up on a hair test even though they may not
have entered your body. While a positive hair test can suggest that you have been exposed to heavy metals, it cannot tell you anything about how much of the metal is in your body or whether or not it is causing disease.

What about Chelation?

Chelation is the main treatment for acute heavy metal poisoning, but its medical
use is generally limited to people with very high levels of the metal and clear

What is the best treatment for chronic heavy metal poisoning?

The safest thing you can do if you are concerned about chronic heavy metal
poisoning is to identify the source and remove it to prevent any further exposure.
Preventing exposure in the first place is ideal. Some easy ways to do this include:
• Limit dust in the home and remove your shoes when you go inside as many
metals collect in dust and dirt.
• Be aware of local fish advisories regarding mercury levels.
• Be aware of sources of lead exposure.
• Read labels on products coming into your home to see if they contain heavy metals.
