By Day 3Postan explanation of the pathophysiological mechanisms of iron deficiency anemia and the anemia you selected. Compare these twotypes of anemia, as well as their potential causes. Finally, explain how genetics, gender, ethnicity, age, and behavior might impact theanemic disorders you selected.Hematological system Anemia occurs as a result of reduced or decreased red blood cell in the body. Anemia happens due to impaired erythrocyte production, blood loss which can either be acute or chronic or increased erythrocyte destruction or combination of the three factors (Huether & McCance, 2017). There are different types of anemia, but only iron deficiency and pernicious anemia will be discussed in this discussion.Pathophysiology of iron deficiency and pernicious anemiaIron deficiency anemia (IDA) is the most common type of anemia that occurs mostly in women compared to men (Hammer & McPhee, 2014). Iron has several vital functions with number one role of transportation of oxygen in the body. IDA can occur as a result of inadequate dietary intake or chronic blood loss (Huether & McCance, 2017). In IDA, the blood iron stores for red cell production and hemoglobin synthesis are depleted leading to the insufficient amount of irons been transported to the marrow and iron deficiency red blood cell are produced.
