 Iron Deficiency Anemia: Encyclopedia of Children's Health
Anemia is a blood disorder characterized by abnormally low levels of healthy RBCs or reduced levels of hemoglobin (Hgb), the iron-bearing protein in RBCs that delivers oxygen to tissues throughout the body.
Iron deficiency anemia is the most common type of anemia throughout the world, although it occurs to a lesser extent in the United States because of the higher consumption of iron-rich red meat and the practice of food fortification (addition of iron to foods by manufacturers).
Iron deficiency anemia can develop as a result of depleted iron stores from chronic blood loss, increased demands for iron as seen in periods of growth (e.g., in infancy and adolescence), or malabsorption of iron even when foods or supplements are supplying adequate amounts.

Megaloblastic anemia due to a deficiency of either vitamin B12 or folic acid (or both) due either to inadequate intake or insufficient absorption.
The cause of megaloblastic anemia is primarily a failure of DNA synthesis with preserved RNA synthesis, which result in restricted cell division of the progenitor cells.

Thalassemia minor, a genetic cause of anemia, is an exception in that it usually causes an increase in the number of red blood cells, but because they are small, it results in a decreased hematocrit.
One of the most common is anemia, which is characterized by a low RBC count, hemoglobin, and hematocrit.
Lack of iron in the diet, thalassemia (a type of hereditary anemia), and chronic illness are the most common causes of microcytic anemia (low MCV).
