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.

Is Mediterranean anemia leukemia?

Thalassemia, formerly known as Mediterranean anemia or oceanic anemia, is a hereditary hemolytic anemia caused by mutations or deletions in globin genes, leading to insufficient synthesis of globin peptide chains. Those who lack beta chains are referred to as having beta-thalassemia, and those who lack alpha chains are known as having alpha-thalassemia. Clinically, it is classified into mild, intermediate, and severe forms based on the severity of anemia. The disease is widespread in many regions of the world, including the Mediterranean, the Middle East, Africa, Southeast Asia, and southern China. In China, it is more commonly found in Guangxi, Guangdong, Sichuan, Hong Kong, northern Taiwan, Yunnan, Guizhou, Hainan, Fujian, Hunan, and Hubei, and less commonly in the north. Thalassemia is fundamentally defined not as leukemia, but as a genetic disease.

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.

Mediterranean anemia has symptoms such as fatigue, paleness, delayed growth, and facial bone deformities.

Thalassemia is a hereditary hemolytic anemia, and the symptoms of patients with thalassemia are related to their specific types. Thalassemia can be divided into mild, intermediate, and severe types. Mild thalassemia clinically may have no symptoms or only mild anemia, sometimes accompanied by mild splenomegaly; Intermediate thalassemia can present with moderate anemia, noticeable fatigue, and splenomegaly, with a few cases experiencing mild skeletal changes and delayed sexual development; Severe thalassemia in children manifests within the first half-year after birth with pallor, progressively worsening anemia, jaundice, hepatosplenomegaly, delayed growth and development, and distinctive facial features such as frontal bossing, a depressed nasal bridge, and increased distance between the eyes.

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)

How to test for thalassemia?

Thalassemia is a genetic disease, a hereditary condition, caused by abnormal production of globin in hemoglobin, leading to hemolytic anemia. Patients with thalassemia should first undergo a routine blood test. If the routine blood test indicates anemia or even if there is no anemia but the red blood cells are very small, it suggests a high possibility of thalassemia. At this point, further screening for thalassemia genes should be conducted to confirm the diagnosis. Once thalassemia is definitively diagnosed, it can be classified as mild, moderate, or severe based on the genotype.
