Thalassemia, also known as hemoglobin synthesis disorder anemia, refers to a group of hemolytic diseases caused by abnormal hemoglobin genes resulting in abnormal hemoglobin protein or quantity. Thalassemia can be divided into α-thalassemia and β-thalassemia, depending on the type of hemoglobin affected. Thalassemia can vary in severity; individuals with mild thalassemia can live for a long time and may not require regular red blood cell transfusion support in daily life, whereas those with severe thalassemia may die shortly after birth.

Can people with thalassemia not take iron supplements?

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.

Can a fetus with thalassemia be kept?

Thalassemia, commonly referred to as "Mediterranean anemia," is a hereditary hemolytic anemia caused by mutations or deletions in globin genes, leading to insufficient synthesis of globin peptide chains. Cases with a deficiency in the globin chain are called thalassemia. Regarding whether a thalassemia fetus should be carried to term, one must first consider the maternal family history, including any history of stillbirths, occurrences of hydrops fetalis (swelling in infants), or cases of severe thalassemia in children, as well as instances where both parents are carriers, marking a high-risk pregnancy. In such cases, strict prenatal diagnosis is required. Prenatal diagnosis includes taking samples of fetal chorion, amniotic fluid, and umbilical cord blood for genetic analysis. If severe thalassemia or Hemoglobin Barts Hydrops Fetalis Syndrome is detected in the fetus, the pregnancy should be terminated immediately. Therefore, it is recommended to terminate pregnancies where the fetus is found to have severe thalassemia or Hemoglobin Barts Hydrops Fetalis Syndrome.

Can carriers of thalassemia have babies?

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 to eat for anemia in thalassemia

Thalassemia belongs to genetic diseases, hereditary diseases. The cause of the disease is due to genetic and chromosomal abnormalities that lead to congenital defects in the quantity or quality of globin production, resulting in thalassemia. Therefore, no matter what thalassemia patients eat, it cannot help in blood replenishment. For thalassemia patients with severe anemia symptoms, the primary treatment method is red blood cell transfusion support therapy, and oral medications are ineffective. It is important to note that thalassemia patients who undergo repeated red blood cell transfusions need chelation therapy.

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.
