Patients with iron deficiency anemia mostly suffer from anemia due to lack of iron, but in a small proportion of cases, the essence of their anemia is due to the number of red blood cells or hemoglobin per unit volume of blood being below normal levels. Therefore, any factor that can lead to reduced production or excessive destruction, or loss of red blood cells or hemoglobin can cause anemia. Can patients with iron deficiency anemia consume vitamin C? The main treatment plan for iron deficiency anemia includes four aspects. First, general treatment aims to prevent and reduce various factors that induce iron deficiency. Second, etiological treatment involves identifying a cause whenever possible and controlling the primary iron deficiency related to that cause, such as actively combatting hookworm infection in cases of hookworm disease, stopping bleeding and actively treating ulcers in cases of ulcerative bleeding, and actively controlling menstrual flow in women with heavy periods. Third is the supplementation of iron, which should ideally be taken with vitamin C as it can enhance the absorption of iron. Therefore, patients with iron deficiency anemia can indeed consume vitamin C.
