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.

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.

What is thalassemia?

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.

What is thalassemia?

Thalassemia, commonly referred to as thalassemia, is a type of hereditary hemolytic anemia caused by mutations or deletions in the globin gene, leading to insufficient synthesis of globin peptide chains. This condition is termed thalassemia when characterized by a deficiency in globin chains. Clinically, based on the severity of the anemia, it is categorized into mild, intermediate, and severe types. The disease is widely distributed in many regions of the world, predominantly prevalent in the Mediterranean area, the Middle East, Africa, Southeast Asia, and southern China, including Guangxi, Guangdong, Sichuan, Hong Kong, northern Taiwan, as well as Yunnan, Guizhou, Hainan, Fujian, Hunan, and Hubei, with less prevalence in the north of China.

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.

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.
