Hello Liz,
Since Nikols has gave some basic information about your question I would just like to add that iron is an essential element that performs a number of functions in the body. One of these very important functions is including oxygen transport.
Too much of the iron in the body is called hemochromatosis. This condition can cause serious health problems especially problems which are related with the liver. Hemochromatosis can be inherited disease but it can also occur as a secondary disease as a result of some other health problems.
When the treatment options are in question the best way to deal with this condition is regular removal of blood intravenously. This acts as an effective treatment for hemochromatosis because iron is carried by red blood cells and removing part of the blood decreases the amount of iron in the body.
