what are the primary causes for normocytic anemia
Congenital normocytic anemia is caused by the breaking up of red blood cells. Sickle cell disease is a congenital disorder of red blood cells. The most common cause of the acquired form of normocytic anemia is a long-term (chronic) disease.Chronic diseases that can cause normocytic anemia include kidney disease, cancer, rheumatoid arthritis and thyroiditis.Some medicines can cause you to have normocytic anemia, but this does not happen often.t means you have normal-sized red blood cells, but you have a low number of them. The presence of normal-sized red blood cells tells your doctor that you have normocytic anemia rather than another kind of anemia. For example, when anemia is caused by having too little iron in your diet, you have small red blood cells.
