Iron overload
A condition in which the body takes up and stores more iron than it needs. The extra iron is stored in the liver, heart, and pancreas, which may cause liver disease, heart problems, organ failure, and cancer.

The MedicineNet physician editors ask:
What were the symptoms and signs with your hemochromatosis (iron overload)?
The iron overload in hereditary hemochromatosis can affect many organs in the body including the:

Hereditary Hemochromatosis (HHC) is characterized by increased iron absorption in the gastrointestinal tract that may cause lifelong excessive iron absorption and accumulation and serious health effects ...
Without treatment, the iron overload causes these organs to stop working, which can lead to death.
Iron overload
Iron overload is a condition in which excess iron is found in the blood and stored in organs such as the liver and heart.
Iron Overload
Getting many blood transfusions can cause too much iron to build up in your blood (iron overload). People who have a blood disorder like thalassemia, which requires multiple transfusions, are at risk for iron overload.
Iron overload disease
See hemochromatosis.
Ischemia
Decreased flow of oxygenated blood to an organ due to obstruction in an artery.
Iron overload is more common than deficiency, however, even in patients without a significant blood product transfusion history. The exact cause of iron overload in sideroblastic anemia patients is unclear.
Iron overload is a particular risk for:
People with certain genetic conditions such as hemochromatosis; and
People receiving repeated blood transfusions.
Iron overload occurs when there is too much iron in the blood. It can be as serious a problem as iron deficiency. Iron overload is usually caused by: ...
Iron overload is one of the key complications of Thalassaemia treatment and a major cause of disability in the condition. Iron builds up in the tissues and has toxic effects on cells.
Iron overload disease is usually due to an inherited condition called hemochromatosis. But it may occur in people who take large amounts of iron over a long period of time.
Iron overload due to altered iron metabolism (juvenile hemachromatosis) or due to frequent transfusions (eg, for thalassemia major)
Nutritional deficiencies

Iron overload (hematochromatosis) affects many bodily organs, including the heart, liver, pancreas, and thyroid, and may result in diabetes mellitus, hypothyroidism, heart failure, and even death.
Iron overload can be prevented with the use of iron chelating therapy. Chelating agents attract the excess iron and assist with the process of binding and detoxifying this iron in the body.
Iron overload can damage various organs in the body. For example: the heart, liver, hormone glands, pancreas (causing diabetes) and bones. So you will need regular blood tests and scans to check the function of these organs.
As the iron overload increases, sufferers may experience the following diseases.
Dietary iron overload

Anemias (eg, thalassemia )

In rare cases, iron overload begins before birth. These cases are called neonatal hemochromatosis. This type of hemochromatosis progresses rapidly and is characterized by liver damage that is apparent at birth or in the first day of life.
HEMOCHROMATOSIS: iron overload disease; a disease in which iron is not properly metabolized and builds up in tissues throughout the body, especially in the liver.
The iron overload results a neurodegeneration (ataxia, dementia and extrapyramidal disorders) and diabetes. Patients with only a partial absence of ceruloplasmin are often asymptomatic.

Because your liver is a primary storage area for excess iron, it's especially likely to be damaged by long-term iron overload. Cirrhosis — permanent scarring of the liver — is just one of the problems that may occur.
Phlebotomy may be used to obtain blood for diagnostic tests or to treat certain conditions, for example, iron overload in hemochromatosis. Phospholipids lipids in which phosphoric acid as well as fatty acids are attached to a glycerol backbone.

hemochromatosis (Also called iron overload disease.) - characterized by the absorption of too much iron from food. Instead of secreting the excess iron, the iron is stored throughout the body, including the liver and pancreas.
Depending on how severe the iron overload is, a pint of blood will be taken once or twice a week for several months to a year, and occasionally longer. Blood ferritin levels will be tested periodically to monitor iron levels.

Although excess iron (iron overload) is a common problem, it's not always the result of hemochromatosis.
This can cause multiple organ failures, as various organs struggle to cope with the iron overload.

The doctors also may focus on the conditions caused by hemochromatosis—arthritis, liver disease, heart disease, or diabetes—rather than on the underlying iron overload.
Hemochromatosis: Hemochromatosis, the most common form of iron overload disease, is an inherited disorder that causes the body to absorb and store too much iron. The extra iron builds up in organs and damages them.
These include an underactive thyroid (hypothyroidism), a genetic disorder of iron overload (hemochromatosis) or excessive blood levels of calcium (hypercalcemia).
This is used to treat iron overloaded patients with thalassaemia major. Specifically, this is used in the group of patients who are unable to take desferrioxamine therapy or where the mentioned therapy has been proven ineffective.
Hemochromatosis is a condition that causes your body to absorb and store too much iron. When your body has too much iron, it's called 'iron overload.' Iron overload can damage your tissues and organs, especially your liver, heart and pancreas.
There are other causes of iron overload, e.g. secondary to thalassaemia and other haemolytic diseases, that may require frequent blood transfusions.

Hemochromatosis is also called iron overload disease.
How does it occur?
Hemochromatosis is caused by an inherited tendency to store too much iron.
The body basically experiences iron overload because it cannot break the iron down very well, so too much is absorbed from the gastrointestinal tract; there are various reasons that can cause too much iron to be absorbed, but this is [...] ...
This operation is more successful in young children who don't suffer from iron overload, but graft rejection or even death can still result. The risks involved mean that bone marrow transplantation is not a viable option for some families.
Regular blood transfusions may minimize physical and mental retardation, but transfusions increase the risk of deadly hemosiderosis and iron overload.
