Reduced hemoglobin is anemia, which may be caused by reduced production, excessive destruction and high blood loss.
1. Reduced erythropoiesis: when certain chemical, physical, viral infection and immune factors damage hematopoietic stem cells and hematopoietic microenvironment, so that the number of hematopoietic stem cells decreases or qualitative abnormality leads to the differentiation and proliferation of the obstacles that occur in the bone marrow hematopoietic failure, the reduction of peripheral blood whole blood cells, the appearance of reduced hemoglobin.
2. Excessive destruction of erythrocytes: due to the increase of erythrocyte destruction, more than the bone marrow hematopoietic compensatory capacity, can also lead to a decrease in hemoglobin, such as hemolytic anemia, anemia caused by hypersplenism.
3. Excessive loss of red blood cells: anemia caused by malignant tumors, nutritional disorders resulting in a lack of hematopoietic substances, erythropoietin reduction, can lead to a decrease in hemoglobin.
If you find that the hemoglobin is lowered, you need to consult a doctor in time to find out the cause and carry out the treatment to avoid delaying the condition.
