Anemia is a large group of disorders, many of the causes of which cannot be supplemented up through food and need to be treated for their causes.
Anemia can have many causes, such as anemia with deficiency of hematopoietic materials, hereditary diseases, chronic blood loss, and autoimmune diseases. In anemia of hematopoietic material deficiency, a lack of iron, vitamin B12 or folic acid in the diet can lead to anemia. Mild anemia may be relieved by consuming foods such as lean meat, pork liver, and green leafy vegetables, but moderate to severe anemia usually requires medication.
While hereditary diseases, such as thalassemia or sickle cell disease, chronic blood loss, such as trauma, surgery, peptic ulcers, excessive menstruation, cancer (especially intestinal cancer) or anemia caused by frequent blood donations, as well as autoimmune disorders such as autoimmune hemolytic anemia, where the immune cells attack the red blood cells and shorten their lifespan, can not be supplemented up through food, and the cause of the anemia needs to be found, then treated. It is necessary to find out the cause of the disease and carry out targeted treatment so that the anemia can be corrected quickly.
