WK7 PATHO2wk7 pathoPostan explanation of the pathophysiological mechanisms of iron deficiency anemia and the anemia you selected. Compare these two types of anemia, as well as their potential causes. Iron Deficiency AnemiaIron deficiency anemia, it the most common type of anemia. In some developing countries iron deficiency in the cause, in developed areas it is attributed to blood loss. Usually the body stores enough iron to last several years. “Dietary iron is primarily absorbed by the duodenum” (Hammer & McPhee, 2014 pg. 127). Iron is constantly in demand from the body, and losing just 2-4 ml a day of blood containing 1-2 mg of iron can cause IDA. There are three stages in which IDA develops. Stage 1 the body’s iron stores are depleted. The next stage not enough iron is transported to the bone marrow causing iron deficient red cell production. The third stage “begins when the hemoglobin-deficient red cells begin circulating to replace normal, aged erythrocytes” (Hammer & McPhee, 2017 pg. 517). It is at stage three that clinical manifestations are present.Sideroblastic AnemiaSideroblastic anemia is characterized by the ringed sideroblasts in the bone marrow. These ringed sideroblast “are erythroblasts that contain iron-laden mitochondria arranged in a circle around 1/3 or more of the nucleus” (Huether & McCance, 2017 pg.518). There are four main types of sideroblastic anemias; acquired, reversible, congenital, and myelodysplastic. For
