Anemia is a manifestation of malnutrition, but it does not mean malnutrition. Anemia in medicine refers to the clinical symptoms of reduced hemoglobin caused by reduced red blood cell production, blood loss, hemolysis, etc. It usually manifests itself in insomnia, pallor, dizziness, tinnitus, and other uncomfortable symptoms. Malnutrition is caused by poor dietary habits and is usually characterized by low body weight, thinness and delayed growth. Severe malnutrition can lead to anemia, which in turn leads to insufficient blood supply and oxygen supply to the brain, and timely treatment in hospital is recommended. Treatment of anemia caused by malnutrition can be improved by diet and oral vitamins. It is recommended to maintain balanced nutrition, eat more meat, dairy products, take oral vitamins, and supplement iron, folic acid, vitamin B12 and other blood-forming raw materials, in order to correct the anemia and increase the oxygen-carrying capacity of the blood, so as not to lead to insufficient blood supply and insufficient oxygen supply. Meanwhile, anemia can be caused by other diseases, such as thalassemia, severe infections, leukemia, etc. At this time, it is necessary to identify the cause of the disease and targeted treatment. When malnutrition and anemia occur, you should go to the hospital in time to check the cause and take measures under the guidance of the doctor to treat the symptoms.
