forms over millions of years in the pore spaces of sedimentary rocks from remains of ocean-dwelling phytoplankton; over time it migrates upward toward the highest point in the porous rock because it is less dense than the rock.
Hereditary hemochromatosis (hee-muh-kro-muh-TOE-sus) is a genetic disease that causes the body to absorb and store too much iron. Iron is an important nutrient that our bodies get from food.
In HFE (Type 1) haemochromatosis it is rare for iron to build up to a damaging level in childhood, and in fact it often does not happen for several decades. Children can however overload iron as a result of Type 2 (Juvenile) haemochromatosis.. Genetic haemochromatosis (GH) is a genetic disorder causing the body to absorb an excessive amount of iron from the diet: the iron is then deposited in various organs, mainly the liver, but also the heart, endocrine glands such as the pancreas, and joints.
