How much rise in Hemoglobin per day expected in iron deficiency anemia for oral iron therapy? - An Explanation This explanation is for the oral preparation. Hb contains 0.33% iron. That means 0.33 gm iron in 100 g Hb. Therefore, 33 mg in 10 g Hb. Now, 200 mg elemental iron per day required orally for treatment or iron deficiency anemia. Approximately 15-20% iron is absorbed from GIT. Suppose 17% is absorbed (for calculative purpose) Therefore, from 200 mg iron 34 mg will be absorbed.
Now, for 10 gm Hb = 33 mg elemental iron. Therefore 34 mg elemental iron will form around 10 gm Hb. This 10 gm Hb will be formed in whole blood volume i.e. 5 L. Therefore 2 gm in 1 L Therefore 0.2gm/dl (100ml) per day rise in Hemoglobin can be expected for iron deficiency anemia for oral iron therapy. * this is only for the purpose of calculation. This is not for dose calculation You can follow my blog…
