Iron deficiency anemia

Anemia can be caused by iron deficiency, folate deficiency, vitamin B12 deficiency, and other causes. The term iron deficiency anemia means anemia that is due to iron deficiency. Iron deficiency anemia is characterized by the production of small red blood cells. When examined under a microscope, the red blood cells also appear pale or light-colored. For this reason, the anemia that occurs with iron deficiency is also called hypochromic microcytic anemia.
