What is iron deficiency anemia?

The role of the red blood cells in our blood is to carryoxygen. Anemia means the absence of adequate healthy, normal red bloodcells in the blood. Blood can not carry the required amount of oxygen tothe body in anemia, and this causes fatigue. Inside the red bloodcells, a substance called hemoglobin, carries oxygen and it is thesubstance that gives the red color to the blood due to the inclusion ofiron in its structure. If a sufficient amount of iron isn’t available aspart of the nutrients consumed as part of a person’s food, then thebody cannot produce hemoglobin. As a result the red blood cells cannotcarry sufficient amount of oxygen. This kind of anemia is called as”iron deficiency anemia”.

Other anemias

  • Vitamin deficiency anemias: Folic acid and vitamin B12
  • Chronic disease anemia: Anemia can arise as the result of some long term diseases: cancer, rheumatoid arthritis, Crohn’s disease. Renal failure also causes anemia.
  • Aplastic anemia: It is a rare form of anemia. In this disorder, bone marrow can not produce the blood cells. It is a severe disease.
  • Anemias related to bone marrow diseases: The bone marrow cannot produce sufficient amounts of red blood cells in some diseases such as leukemia, myelodysplasia, multiple myeloma, and lymphomas.
  • Hemolytic anemia: It’s a kind of anemia where red blood cells easily break down. They break up so rapidly that the bone marrow cannot replace them fast enough. This can be the result of some diseases that cause immune system dysfunction, or be caused by some drugs.
  • Sickle- cell anemia: A hereditary disease. There is an abnormality in the hemoglobin, and while red blood cells are normally disk-shaped, in this disease they are crescent-shaped, like a sickle.
  • Thalassemia: A hereditary disease related to a specific hemoglobin abnormality.
