Thalassemia is a hereditary disease, classified as hemolytic anemia. Patients with thalassemia do not suffer from iron deficiency; rather, the anemia is caused by thalassemia itself, and iron supplementation is ineffective. However, if a patient with thalassemia also has concurrent iron deficiency anemia, then iron supplementation is necessary. During iron supplement treatment, it is also essential to conduct comprehensive examinations to ascertain the cause of the iron deficiency anemia and address the underlying cause.

What should I do about thalassemia?

Thalassemia is a hereditary hemolytic anemia. Currently, there is no specific cure for thalassemia, and treatment mainly involves symptomatic management based on the type and severity of the disease. This includes red blood cell transfusions, prevention of secondary hemosiderosis, and splenectomy, along with targeted prevention and treatment of factors that induce hemolysis, such as infections. Splenectomy is appropriate for patients whose transfusion needs are increasing, accompanied by splenic hyperfunction and significant compression symptoms. For patients with a suitable HLA-matched donor, allogeneic hematopoietic stem cell transplantation can be performed, which is currently the only effective treatment capable of curing thalassemia. Although mild thalassemia cannot be cured, prenatal genetic diagnosis is crucial for eugenics, effectively preventing the birth of fetuses with thalassemia and playing an important role in genetic health care.

Dietary Considerations for Thalassemia

Thalassemia, also known as hemoglobin synthesis disorder anemia, is a genetic disease that falls under the category of genetic disorders. It is caused by abnormalities in the genes related to globin, leading to a deficiency in globin quantity, which in turn causes thalassemia. Since thalassemia is a genetic disorder, there are no specific dietary considerations. The severity of thalassemia is also defined by the number of affected genes; the fewer the affected genes, the milder the condition.

The difference between iron deficiency anemia and thalassemia

Iron deficiency anemia and thalassemia have similarities in that both are classified as microcytic hypochromic anemia. However, iron deficiency anemia and thalassemia are two distinct diseases that require further differential diagnosis. Iron deficiency anemia is caused by iron deficiency, often due to chronic blood loss, and it can be cured if the cause is removed and iron supplementation treatment is provided. Thalassemia is a genetic disease with hereditary factors, and there is no particularly effective treatment; iron supplementation is ineffective. Treatment mainly involves red blood cell transfusions and is not curable.

What to do and what to eat for dizziness caused by thalassemia?

Patients with thalassemia who experience dizziness first need to analyze the cause of the dizziness. The vast majority of causes of dizziness are not related to diet, nor can they be corrected by eating certain foods. For patients with thalassemia experiencing dizziness, it is first necessary to consider whether the cause is worsening anemia. A drop in hemoglobin can lead to ischemia and hypoxia in the body, which can manifest as symptoms of dizziness in the nervous system. If it is confirmed that the dizziness is caused by worsening anemia, then blood transfusion treatment is needed, usually requiring the transfusion of washed red cells. Once the anemia is corrected, the symptoms of dizziness can disappear. At the same time, folic acid supplements can be added to provide raw materials for hematopoiesis. Other possible causes of dizziness include diseases such as cranial, cervical spine, and otolithiasis, all of which require further differential diagnosis. (The use of drugs should be carried out under the guidance of a physician)

Mediterranean anemia's blood routine manifestations

The hematological manifestations of thalassemia, including those of silent gene carriers, generally show normal complete blood counts. In thalassemia and mild thalassemia, hemoglobin levels are normal or slightly decreased. Patients with Hemoglobin H disease have hemoglobin levels between 70-100 grams per liter. In cases of Hemoglobin Bart's hydrops fetalis syndrome and severe thalassemia, hemoglobin levels are typically below 50 grams per liter, falling into the category of severe anemia, requiring regular blood transfusions for survival. Their MCV, MCH, and MCHC are significantly decreased. Blood smears may reveal anisocytosis and poikilocytosis including target cells, and even nucleated red cells, with a marked increase in reticulocytes. Typically, the white blood cell count remains normal for such patients, although the platelet count may be slightly elevated. During periods of increased spleen activity, there may be a reduction in both white blood cells and platelets. These are the hematologic features observed in different thalassemia patients.
