The key is to clarify the diagnosis of anemia and carry out treatment as soon as possible. Treatment suggestions are as follows: 1. Go to the hospital for routine blood tests as soon as possible. If the routine blood tests indicate that the hemoglobin is below 60g/L, red blood cells can be transfused to quickly correct the anemia within a short period of time; 2. Complete three tests related to anemia, bone marrow aspiration, reticulocyte count, abdominal ultrasound, etc. Clear the diagnosis of anemia and carry out targeted treatment; 3. Oxygen intake is also helpful to improve the symptoms. The fainting of anemic patients is due to the decrease of hemoglobin concentration and the decrease of red blood cell count, which leads to the decrease of oxygen transportation and the lack of oxygen makes the brain ischemic and hypoxic, thus causing syncope.
