Thalassemia minor does not affect children in a very noticeable way. Thalassemia minor generally refers to thalassemia minor, also known as thalassemia minor. Thalassemia is a hemolytic anemia caused by congenital abnormality of hemoglobin peptide chain synthesis. It is a common genetic defect disease and is clinically classified as mild, moderate and severe. Most of the mild thalassemia is due to one parent being a gene carrier of thalassemia, and the mild patients themselves are also gene carriers of thalassemia. Measurements of hemoglobin concentration and red blood cell count can be normal or nearly normal, and the average volume of red blood cells, average hemoglobin content, and average hemoglobin concentration are all lower than normal, but they can lead a normal life without any special treatment. Regular checkups are recommended for children with mild thalassemia. Normally, they should eat more blood-supplementing foods, such as spinach, pig liver, pig blood, etc., and make sure the nutrition is balanced.
