###Human: Hb is reducing in beta thalassemia minor patient who is pregnant. Why? ###Assistant: Hi. Thalassemia minor is hemoglobinopathy and so hemoglobin level can never be above 12 in such patient. In pregnancy, plasma is increased and so hemodilution can lead to more fall in hemoglobin level in CBC. Orofer XT like Iron tablet can be prescribed for such case. It would be great if the Hb level remains around 9 or 10 during pregnancy. The Iron infusion can be given in second or third trimester of pregnancy only if needed. You can discuss all these with your treating doctor or hematologist. No other mode of treatment is available as per my opinion. Close watch up is necessary in such case. I would like to suggest you to investigate with HB electrophoresis as well to avoid thalassemia major child.
