Postan 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. Finally, explain how genetics, gender, ethnicity, age, and behavior might impact the anemic disorders you selected.Iron Deficiency AnemiaIron deficiency anemia is the most common type of anemia that is seen in underdeveloped and developed countries (Hammer & McPhee, 2014). It can result from chronic blood loss, not taking in enough in an individual’s daily diet, inadequate iron delivery and absorption or caused by a metabolic disorder (Huether & McCance, 2017). Iron has the ability to be recycled by the body so the body can use the iron as hemoglobin or store it for making hemoglobin in the future (Huether & McCance, 2017). The most common cause of iron deficiency anemia is blood loss, which can offset the balance of iron usage for hemoglobin and iron being stored (Huether & McCance, 2017). Iron Deficiency anemia occurs in a three-step process in which the first step consists of emptying of the iron that has been stored hemoglobin synthesis (Huether & McCance, 2017). Stage two occurs when iron deficiency red cell production starts in the bone marrow (Huether & McCance, 2017).
