Iron-deficiency anemia the cause and severity of the condition. If the iron-deficiency anemia is a result of blood loss or another underlying cause, treatment is geared toward addressing the underlying cause. Most cases of iron deficiency anemia are treated with oral iron supplements. In severe acute cases, treatment measures are taken for immediate management in the interim, such as blood transfusions or intravenous iron. For less severe cases, treatment of iron-deficiency anemia includes dietary changes to incorporate iron-rich foods into regular oral intake and oral iron supplementation. Foods rich in ascorbic acid (vitamin C) can also be beneficial, since ascorbic acid enhances
Vitamin B12 deficiency anemia corpuscular volume (MCV), as well the mean corpuscular hemoglobin concentration (MCHC). PA is identified with a high MCV (macrocytic anemia) and a normal MCHC (normochromic anemia). Ovalocytes are also typically seen on the blood smear, and a pathognomonic feature of megaloblastic anemias (which include PA and others) is hypersegmented neutrophils. Serum vitamin B levels are used to detect its deficiency, but they do not distinguish its causes. Vitamin B levels can be falsely high or low and data for sensitivity and specificity vary widely. Normal serum levels may be found in cases of deficiency where myeloproliferative disorders, liver disease, transcobalamin
