What is iron deficiency anemia?
Iron deficiency anemia is a reduction in the number of healthy red blood cells produced due to an insufficient supply of iron in the body. It is the most common cause of anemia in the United States. Red blood cells carry oxygen from the lungs to the rest of the body. A reduction in red blood cells limits the amount of oxygen reaching your limbs and organs and may cause various symptoms, including fatigue, dizziness, and pallor (pale skin).
Low levels of iron may be caused by blood loss, by the body’s inability to absorb sufficient iron from the digestive tract, or by low levels of iron in your diet. Pregnancy is also a cause of iron deficiency anemia in women due to the iron requirements of the growing fetus. Iron deficiency anemia is the most common type of anemia in the United States. Approximately one-fifth of women and half of women who are pregnant, as well as 3% of men, do not have enough iron in their body and are at risk of developing iron deficiency anemia (Source: NIH).
Iron deficiency anemia is usually treated successfully with dietary changes and iron supplements. In severe cases, blood transfusions may be necessary. In many cases, iron deficiency anemia can be prevented by adequate dietary intake of iron or the use of iron supplements in people who are at risk.
Symptoms of iron deficiency anemia are often mild. Rarely, severe iron deficiency anemia may cause serious symptoms. Seek immediate medical care (call 911) if you develop serious symptoms such as difficulty breathing or chest pains. Seek prompt medical care if you are being treated for iron deficiency anemia but have persistent or recurrent mild symptoms.

What causes iron deficiency anemia?
Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to other body tissues. Hemoglobin is made primarily of iron. When your iron levels are low, your body makes fewer red blood cells or makes red blood cells with less hemoglobin, and these cells cannot carry as much oxygen. Low iron levels may result from a diet lacking in iron, an inability to absorb enough ... Read more about iron deficiency anemiacauses
