What Is Iron Deficiency Anemia?

Iron deficiency anemia is a type of anemia caused by iron deficiency which ultimately results in a lack of blood. Iron is a substance that forms hemoglobin, a protein that helps red blood cells carry oxygen throughout the body. If a person does not have enough iron, the body does not produce enough red blood cells so the body becomes deficient in hemoglobin, which carries oxygen. If you don’t have enough oxygen in your blood, you may feel tired, weak, and short of breath.

  • Causes of Iron Deficiency Anemia
  • Someone who has iron-deficiency caused by the following things:

Poor Diet

Poor diet is a major cause of iron deficiency anemia because the body regularly gets iron from the food you eat. For that, consume foods that contain lots of iron, such as eggs, meat, green vegetables, and iron-fortified foods. This food is needed by the body to produce hemoglobin.

Blood Loss

Iron can be found mainly in blood because it is stored in red blood cells. If you lose a lot of blood due to an accident, injury, childbirth, or heavy menstruation, you may experience iron deficiency.

However, in some cases, blood loss due to chronic disease or some cancer can cause iron deficiency.

Ability to absorb reduced iron

Although rare, some people cannot absorb enough iron from the food they eat. The reason may be due to problems in the small intestine, such as celiac disease or Crohn’s disease, or if a portion of the small intestine has been removed.


Low levels of iron are commonly experienced by pregnant women because iron reserves in the body to meet the increase in blood volume, which is a source of hemoglobin for fetal development in the womb.

Endometriosis If a woman suffers from endometriosis, she may experience a loss of blood that cannot be realized because it is hidden in the abdomen or pelvis and caused iron deficiency anemia.
