Thalassemia carriers refer to individuals where one of the four genes is a pathogenic gene. Such patients can have children. However, it is advised that the other parent of the child be completely normal. Even if the other parent is completely normal, the child has a fifty percent chance of being completely normal and a fifty percent chance of also being a carrier of thalassemia. However, although they are carriers of thalassemia, they usually do not exhibit obvious symptoms of anemia, generally having no anemia or only very mild anemia.

What impact does thalassemia have on the fetus?

Thalassemia is a common autosomal genetic disease with a high incidence in the southern regions of our country, divided into alpha type and beta type, and based on severity, it is further classified into silent, mild, moderate, and severe types. For fetuses with silent and mild thalassemia, there are usually no obvious symptoms, and no treatment is required; for moderate and severe thalassemia fetuses, we aim to prevent their birth, so it is necessary to conduct relevant tests on both spouses before and during early pregnancy to determine whether they carry the pathogenic genes for thalassemia. For fetuses with moderate or severe thalassemia, intrauterine growth retardation, abnormal skeletal development, and enlargement of the liver and spleen can occur; fetuses with severe thalassemia mostly die in utero or after birth. Fetuses with moderate thalassemia require long-term treatments after birth, such as blood transfusions, iron removal, and splenectomy, and even with such treatments, it is difficult for them to develop into adulthood.

Do you still need to get tested for Mediterranean pregnancy after pre-pregnancy testing?

After checking for thalassemia before pregnancy, it is still necessary to check again after becoming pregnant. The purpose of the thalassemia test is to examine some genes to see if there are any genetic issues. Additionally, the husband also needs to be cautious to see if there is a possibility of hemolysis occurring. The thalassemia screening test is aimed at those who have severe hemolysis, or have previously given birth to a child with thalassemia, or if one of the spouses is a carrier of thalassemia trait, then a re-examination is necessary.

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 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 should I eat if I occasionally feel dizzy due to thalassemia?

Patients with thalassemia who experience dizziness typically indicate worsening anemia, and can take folic acid tablets orally. Folic acid is an important raw material for the production of red blood cells, and supplementing with folic acid aids in the recovery from anemia. Thalassemia is a hereditary hemolytic anemia, and there is currently no specific drug for its treatment; it is primarily managed symptomatically. If the anemia is severe, red blood cell transfusions may also be used to correct the anemia. Additionally, severe thalasemia may consider allogeneic hematopoietic stem cell transplantation. Apart from anemia, further investigations should be conducted to rule out cervical spondylosis, cerebrovascular diseases, and otolithiasis when dealing with dizziness in thalassemia patients.
