Hemoglobin is the amount of hemoglobin, which can be determined by routine blood tests to check hemoglobin concentration. Low hemoglobin means that the concentration of hemoglobin in the blood is lower than normal, which is also called anemia; abnormally high hemoglobin is called erythrocytosis.
The normal hemoglobin content of adult men is 120-160g/L, the normal value of adult women is 110-150g/L, and the normal value of newborn babies is 170-200g/L.
1. There are many causes of anemia, such as massive blood loss, iron deficiency, hypersplenism, hemolysis, vitamin deficiency, bone marrow hypoplasia, etc. It manifests itself as pallor, dizziness, weakness, and decreased activity endurance. When blood routine shows low hematocrit, further examination should be done to clarify the cause of the disease, and red blood cells need to be imported to alleviate the symptoms of anemia if necessary.
2. Erythrocytosis can be divided into primary and secondary.
The cause of primary erythrocytosis is unknown, which may be related to the abnormal proliferation of bone marrow erythroid stem cells, and some patients may develop erythroid leukemia. Secondary erythrocytosis is caused by the enhancement of certain factors in the body that promote the proliferation of red blood cells, and is commonly seen in certain chronic heart and lung diseases, kidney diseases, and certain tumors.
Diagnosis and treatment of specific diseases should be under the supervision of a physician.
