Hemoglobin is a special protein that transports oxygen within red blood cells. Leukemia is often associated with low hemoglobin, which is often referred to as anemia, and can be treated with medication, blood transfusion, and surgery. Leukemia is a malignant clonal disease due to hematopoietic stem progenitor cells, which is mainly manifested by anemia, infection and bleeding. 1. Drug therapy: mainly for leukemia treatment, such as chemotherapy drugs, tyrosine kinase inhibitors such as imatinib for treatment. By treating leukemia, it indirectly inhibits the malignant proliferation of bone marrow and promotes hematopoiesis. 2. Blood transfusion therapy: if the anemia is severe, concentrated red blood cells can be transfused to achieve the purpose of supplementing hemoglobin. 3. Surgical treatment: If necessary, treatment such as hematopoietic stem cell transplantation can be performed. Some foods such as animal offal and spinach are rich in iron and vitamins, which should be supplemented in daily life. However, food cannot replace medicine, and it is recommended to carry out standardized treatment under the guidance of doctors.
