Anemia is a decrease in the number of red blood cells in your body or a decrease in hemoglobin synthesis. Mild anemia does not affect you or your life, and you may not notice it until you are examined, but severe anemia can cause your body tissues to not receive enough oxygen and you may experience symptoms such as shortness of breath, dizziness, easy fatigue, etc. There are many types of anemia, and the common type in daily life is nutritional iron deficiency anemia caused by a lack of iron in our diet. If the iron intake in our food does not meet our body’s needs, or if our body excretes more iron than we take in, it further develops into iron deficiency anemia. Whereas iron deficiency anemia can be cured by using iron supplements, thalassemia is completely different, as it is a genetic anemia, a group of inherited hemolytic anemia diseases. Thalassemia is a group of inherited hemolytic anemias, which is an anemia or pathological condition caused by the absence or deficiency of synthesis of one or more of the globin chains in hemoglobin due to a genetic defect. Due to the complexity and diversity of the genetic defects, the type, quantity and clinical symptoms of the deficient nucleoprotein chains are highly variable. It cannot be cured with drugs.
