Thalassemia is caused by genetic abnormalities. Pregnant women with thalassemia and a hemoglobin of 72g/L can eat more animal blood products and meat during pregnancy to supplement blood-forming materials. Thalassemia is a hereditary disease caused by genetic abnormality, and there is no medicine that can cure it fundamentally. Therefore, pregnant women with thalassemia who have a hemoglobin of 72g/L can pay attention to their daily diet and eat more animal blood products, meat and other foods rich in iron and protein to replenish blood-forming raw materials for the body. If the hemoglobin of pregnant women with thalassemia is still not elevated after positive dietary adjustments, or when pregnant women experience symptoms such as dizziness, weakness, fainting, etc., they need to go to the hospital in time for medical consultation, and undergo blood transfusion treatment if necessary. Although foods such as animal blood products and meat rich in iron and protein can provide pregnant women with raw materials for hematopoiesis, they do not have the effect of treating thalassemia, and if you want to treat thalassemia, you need to carry out regular treatment under the guidance of professional doctors.
