Severe anemia means that the hemoglobin concentration in peripheral blood is less than 60g/L, which is the type of severe anemia. What is the fastest way to get results from severe anemia depends on the cause of the anemia, for example, if you are a patient with severe iron deficiency anemia, you can take iron-supplementing drugs and also eat more iron-rich foods, such as animal liver, pig’s blood, sheep’s blood, purple cabbage, black fungus and shiitake mushrooms. These foods are rich in iron, and by consuming them, the concentration of iron in the body can be increased, promoting the formation of more hemoglobin in red blood cells, thus improving the symptoms of anemia. While consuming these iron-rich foods, it is necessary to take iron supplementation medications for treatment. Commonly, there are two-dimensional ferrous iron granules, compound three-dimensional ferrous iron oral solution, and dextran iron tablets, etc.
