Microcytic anemia; ➡️ Microcytic anemia, characterized by small red blood cells and low levels of circulating hemoglobin, is the last stage of a long period of iron deficiency. ➡️The main causes of irondeficiency anemia are heavy blood loss,inadequate iron intake or absorption, orincreased iron needs due to pregnancy,infancy, or adolescence. ➡️First, the storage forms of iron in the form of ferritin and hemosiderin are depleted. ➡️ Second, the amount of iron supplied to the bone marrowis not sufficient to produce healthy bloodcells. ➡️Those that are produced are small and low in hemoglobin. ➡️This eventually results inanemia.
