GSTM1 and Iron deficiency anemia: IDA is the final state of iron depletion due to inability to maintain physiologic balance of iron uptake and utilization.[2] Iron deficiency depresses the erythropoietic system resulting in decreased hemoglobin (Hb) levels.[3] Anemia in women is defined by the World Health Organization as an Hb level < 12 g/dL in nonpregnant women and < 11 g/dL in pregnant women.[4] The prevalence of IDA among pregnant women increases from 6.9% in the first trimester to 14.3% and 28.4% in the second and third trimesters, respectively.[5]
