Mild thalassemia does not heal itself. Thalassemia, also known as marine anemia, is a hereditary disorder that is caused by chromosomal hemoglobin abnormalities. Patients may have impaired synthesis or insufficient synthesis of the peptide chain of the beads protein, which manifests itself in the symptoms of anemia of different degrees of mild, moderate and severe. Therefore, even mild thalassemia cannot be cured and can only be treated according to the symptoms. Patients with mild thalassemia can take appropriate supplements of folic acid and vitamin B12 to promote bone marrow hematopoiesis and improve the symptoms of anemia, and splenectomy is also an option for some patients. Although mild thalassemia cannot be cured by itself and usually has no obvious symptoms, if there is any discomfort, it should be treated actively. If thalassemia is diagnosed, it is recommended to carry out standardized treatment as early as possible to reduce the adverse effects of the disease.
