Whether or not there is a problem with a low red blood cell count needs to be judged according to other conditions, such as whether or not the hemoglobin is lowered and whether or not there are clinical signs of anemia. If the hemoglobin level is normal, only the number of red blood cells is a little low, and there are no clinical signs of anemia, such as dizziness, fatigue, increased heart rate, etc., it is generally not important, usually due to some physiological factors, and does not require special treatment. You can continue to observe and have regular checkups. If the number of red blood cells is low and accompanied by a decrease in hemoglobin count, as well as dizziness, fatigue and other clinical manifestations of anemia, it is necessary to consult a doctor in a timely manner, improve the relevant examinations, such as blood routine, bone marrow hematopoiesis, etc., to determine the cause of the disease, and according to the cause of the disease for appropriate treatment.
