Iron overload

Iron overload, also known as hemochromatosis, is a condition characterized by excessive iron accumulation in the body, which can lead to various health problems. Estrogen is one of the primary factors that contribute to iron overload, as it increases hepcidin levels, which in turn lead to increased iron absorption from food 1. This effect is reversed by progesterone, which has an opposite effect on hepcidin 1.

Chronic stress is another factor that contributes to iron overload, as it activates the heme oxygenase enzyme, which breaks down heme groups and releases iron, carbon monoxide, and bilirubin into the bloodstream 3. This process is exacerbated by the lowered hepcidin levels under stress, which leads to increased iron retention from food 7. Inflammation, specifically pro-inflammatory cytokines, interleukins, and prostaglandins, also activates aromatase, producing estrogen, which further contributes to iron overload 3.

Iron overload is associated with various health problems, including increased susceptibility to infection, inflammation, and coagulation 5. Removal of excess iron through chelation has been proposed as a potential treatment for iron overload, although some chelators can move harmful metals from the bones into the brain and kidneys 5.

Interestingly, anemia, which is often associated with iron deficiency, is not necessarily a reflection of low iron levels, but rather a reflection of low blood, low hematopoietin, and low hemoglobin 6. In fact, studies have shown that children with low hemoglobin levels are healthier than those with normal levels 6.

Overall, iron overload is a complex condition that is influenced by various factors, including estrogen, chronic stress, and inflammation. Understanding the mechanisms underlying iron overload is crucial for developing effective treatments and preventing its associated health problems 8.
