Patients bleed excessively due to trauma or surgery, in this case, it is recommended that patients can properly eat more animal liver, red dates and red rice in soup after the injury, which can accelerate blood replenishment. In addition, patients are advised to eat duck blood appropriately, which can also play a role in blood replenishment. At the same time, patients can replenish blood through medication, for example, they can drink compound red blood replenishing oral liquid, or compound multivitamin iron oral liquid, both of which can achieve the purpose of effective blood replenishment. Patients are advised to make sure to have regular blood tests. If the symptoms of anemia become lighter and lighter, and the initial appearance of anemia, it is recommended to stop taking these drugs appropriately. If the anemia appears to be more and more serious, it must be treated in hospital in time to avoid severe anemia due to local bleeding, which may seriously affect the patient’s life safety. If the anemia is more severe, reaching below 60g/L, it is recommended that the patient receive symptomatic treatment such as blood transfusion in a timely manner.
