The main reasons for low red blood cell count include decreased erythropoiesis, excessive destruction of red blood cells, and acute and chronic blood loss.
1. Reduced erythropoiesis: The production of red blood cells depends on three factors: hematopoietic cells, hematopoietic regulation and hematopoietic raw materials, and any one of these factors may lead to reduced erythropoiesis. For example, aplastic anemia, pernicious leukemia, iron deficiency anemia, etc., will cause the number of red blood cells is low.
2. Excessive destruction of red blood cells: some hemolytic anemias, thalassemia, and some mechanical hemolytic anemias can cause excessive destruction of red blood cells, which can lead to low red blood cell count.
3. Acute and chronic blood loss: hemorrhage, trauma, or chronic blood loss from the digestive tract after surgery can also cause a decrease in red blood cell count.
There are many reasons for low red blood cell count, you should go to the hospital in time for detailed examination, to clarify the cause of the disease and correct treatment.
