The presence or absence of anemia symptoms depends on the degree of anemia, the speed of anemia, the change of circulating blood volume, the age of patients and the compensatory ability of cardiovascular system. Anemia occurs slowly, and the body can adapt gradually. Even if anemia is serious, it can still maintain its physiological function. On the other hand, if anemia occurs in a short time, even if the degree of anemia is not serious, obvious symptoms can appear. Symptoms are more obvious in the elderly, the weak or those with decreased cardiopulmonary function.

Suggest diet therapy and blood supplement.
