Patients with thalassemia who are also iron deficient may be given dietary supplements, blood replenishing drugs, blood transfusions, splenectomy, and allogeneic hematopoietic stem cell transplantation. The following is an analysis from two aspects: light type and medium and heavy type. 1. If mild thalassemia is accompanied by iron deficiency anemia, iron supplementation food can be given in general, such as spinach, pig liver, duck blood, etc. If the effect of dietary supplementation is not obvious, it can be given to the patients with iron deficiency. If the effect of food supplementation is not obvious, iron supplementation can be given, such as ferrous succinate or ferrous fumarate. 2. If it is medium or heavy thalassemia, blood transfusion treatment, splenectomy, allogeneic hematopoietic stem cell transplantation, etc. can be given according to the condition. If thalassemia patients are diagnosed with iron deficiency at the same time, it is recommended to have standardized treatment as early as possible to reduce the adverse effects of the disease. Do not self-medicate, but use medication under the guidance of a doctor.
