Anemia and dizziness can be relieved as follows: 1. Increase the number of red blood cells: In severe anemia, the patient can be given an infusion of red blood cells. Just as for a person who is about to die of hunger, he should be allowed to eat first and then earn money second is the same reason; 2. If the patient is given oxygen when dizziness is obvious, the symptoms will also be improved after increasing the inhaled oxygen capacity. However, all the above treatments are treating the symptoms but not the root cause. The most fundamental thing is to treat the cause of anemia. Anemia causes oxygen deficiency in the body because red blood cells have the function of carrying oxygen. The organ that is most sensitive to oxygen is the brain, because there is no energy reserve in the brain tissue. Muscles have muscle glycogen to reserve energy. The organ with the best energy reserves is the liver, because there is a reserve of liver glycogen, which can be released until a certain state, such as not eating. In the rescue of brain hypoxia is called the golden 3 minutes, the golden 4 minutes, because the brain can use the energy can only maintain a few minutes. Anemia is a decrease in the number of red blood cells per unit volume, and after the decrease in red blood cells there will be hypoxia and dizziness.
