The possible reasons why anemia has been poorly treated include the following, namely, whether the diagnosis is clear, whether the treatment chosen is correct, and whether the course of treatment is adequate, as follows: 1. Clear diagnosis: there are many types of anemia, and different types of anemia are treated differently, so for patients with anemia, a clear diagnosis is crucial. 2. Treatment modality: the treatment modality of anemia is also an important reason, for iron deficiency anemia, mainly oral iron supplementation drugs, if the oral effect is not good, consider whether there is absorption disorder caused by gastrointestinal diseases, and consider intravenous application of iron supplementation drugs. 3, treatment cycle: different anemia treatment cycle is also different, for example, megaloblastic anemia is usually treated in 2-4 weeks, while iron deficiency anemia should be treated for at least 3-6 months.
