Mercury poisoning

How much mercury are you taking and what should you expect in your health?

There are many forms of body poisons, and one that some people have to contend with today is Mercury poisoning. What exactly is Mercury poisoning? You may ask. Well, this is human or animal body poisoning as a result of excessive exposure to mercury. This can be either through the diet or in one’s environment. Mercury is a heavy metal, and it is highly toxic to humans. Therefore, sustained consumption of food with mercury, whether in small or moderate amounts, leads to poisoning.

At room temperature, mercury is a liquid, and it quickly evaporates into the air. Some of the Mercury that we take into our bodies is borne of industrial process like burning coal for power. Usually, vaporized mercury ends up in the soil, water, and rain, where it generally poses a risk to humans, plants, and animals.

The doctor who associates your symptoms with mercury poisoning may want to know a bit more about your physical environment ie, where you live and work. After that, they may run a blood or urine test to gauge the levels of mercury in the body.


The doctor may recommend a change of diet in case your diagnosis points to dietary exposure. And in case mercury features on your list of residential or occupational hazards, you will be advised to relocate or change jobs.

Some severe cases of mercury poisoning may require a type of treatment called Chelation Therapy. Chelation is the process of using drugs to remove mercury from the organs so that the body can dispose of it. The medication comes with its share of side effects, so it is better to go for it when it is necessary.

So far, there is no standard cure for mercury poisoning, so it is better to avoid exposure in the best way that you can.
