Pathophysiology of Iron Deficiency Anemia (IDA) & Causes According to Huether & McCance, anemia is defined as the reduction of erythrocytes in circulation or decrease in volume of hemoglobin. Anemia is typically caused by impaired erythrocyte production, blood loss either acute or chronic, increased erythrocyte destruction, or a combination of these factors together. The classification is based on cause or changes in size, shape, or substance of the erythrocyte (Huether & McCance, 2017). Iron deficiency anemia (IDA) is classified as microcytic due to its decreased mean corpuscular volume (MCV) (Hammer & McPhee, 2014). This is caused by either inadequate dietary intake, chronic blood loss or a combination of both due to menorrhagia, ulcers, hiatal hernia, esophageal varices, cirrhosis, hemorrhoids, ulcerative colitis, cancer, NSAIDs, surgical procedures, eating disorders, and H. pylori infection. IDA develops in the process of three overlapping stages: iron stores for red blood cell production and hemoglobin synthesis are depleted, insufficient amounts of iron
