Anemia due to a deficiency of vitamin B12 or folate is also curable. Taking vitamin supplements and eating healthy will allow your body to increase the number of red blood cells.
However, there are also other types of anemia that are chronic and cannot be treated. Some types are even hereditary. The types of anemia that cannot be cured include thalassemia, sickle cell anemia, anemia associated with chronic diseases, and autoimmune hemolytic anemia.
