Iron deficiency anemia (IDA) is the most common nutritional deficiency worldwide and a significant cause of morbidity in adults. It develops when the body's iron stores are depleted, impairing hemoglobin synthesis and leading to a reduction in red blood cell production. This condition presents with specific clinical features, laboratory findings, and requires thorough workup to identify underlying causes and determine appropriate treatment strategies.

Signs and Symptoms of Iron Deficiency Anemia

Patients with iron deficiency anemia often exhibit a constellation of symptoms resulting from decreased oxygen delivery and tissue hypoxia. Common clinical manifestations include fatigue, weakness, and dizziness, which are primarily due to reduced hemoglobin levels impairing oxygen transport (Camaschella, 2019). Shortness of breath on exertion occurs because of hypoxia-induced stimulation of ventilatory mechanisms. Additionally, patients may experience pallor, especially of the skin and conjunctiva, owing to decreased hemoglobin concentration. Other features include brittle nails, glossitis, and pica—the craving for non-nutritive substances—a hallmark of iron deficiency (Killip et al., 2019). These signs are often subtle initially but become more evident as anemia worsens.

Laboratory Findings and Their Support for Diagnosis

John Doe’s laboratory results reveal classical features of iron deficiency anemia. His hemoglobin (Hb) level of 9.5 g/dL indicates anemia, considering the normal range for males is 13.5-17.5 g/dL (World Health Organization [WHO], 2011). The hematocrit (Hct) of 29% supports the diagnosis, as it is below the normal range of 40–50%. The mean corpuscular volume (MCV) of 75 fL is decreased, indicating microcytic anemia, which is characteristic of iron deficiency (Camaschella, 2019). Serum iron is markedly low at 25 mcg/dL, reflecting depleted iron stores available for erythropoiesis. Elevated total iron binding capacity (TIBC) signifies increased transferrin levels attempting to transport available iron, characteristic of iron deficiency (Killip et al., 2019). The serum ferritin level, at 10 ng/mL, indicates depleted iron stores, as ferritin is the primary intracellular iron storage protein, and low levels are specific for iron deficiency. Altogether, these lab findings—microcytic, hypochromic anemia with low serum iron and ferritin—support the diagnosis of iron deficiency anemia (Camaschella, 2019).

Potential Causes of Iron Deficiency Anemia in Adults and Further Investigations

In adults, iron deficiency anemia can arise from multiple causes, including inadequate dietary intake, malabsorption, chronic blood loss, and increased physiological requirements. In men and postmenopausal women, chronic blood loss from gastrointestinal bleeding, hemorrhoids, or malignancies is a common etiology (Camaschella, 2019). In women of reproductive age, menorrhagia is a frequent culprit. Malabsorption syndromes, such as celiac disease or Helicobacter pylori infection, impair iron absorption in the gut (Lewis et al., 2017). Additionally, poor dietary intake, especially in individuals with restrictive diets, can contribute to deficiency.

Further investigations for this patient should include a comprehensive history and physical examination to identify potential bleeding sources or malabsorption signs. Laboratory assessment may involve stool occult blood testing, endoscopy, colonoscopy, and imaging studies if gastrointestinal bleeding is suspected. Screening for Helicobacter pylori and celiac disease serology may be indicated. Also, assessing serum transferrin saturation and reticulocyte hemoglobin can provide further insights into iron status and marrow response. Since his occupation suggests potential for repeated microtrauma or exposure to harmful substances, these factors should also be evaluated (Lewis et al., 2017). A complete blood count with indices, blood smear examination, and ferritin measurement are essential first-line tests, supplemented by endoscopic evaluation if gastrointestinal blood loss is suspected.

Treatment Options for Iron Deficiency Anemia

The mainstay of treatment for iron deficiency anemia involves replenishing iron stores and correcting the underlying cause. Oral iron therapy, typically ferrous sulfate (200 mg thrice daily), is the first-line treatment due to its efficacy, safety, and cost-effectiveness. It usually results in hemoglobin normalization within 2-3 months, with iron stores replenished over 6 months (Camaschella, 2019). Patients should be counseled about possible gastrointestinal side effects, such as constipation and nausea, and advised to take iron with vitamin C-rich foods to enhance absorption. In cases where oral iron is contraindicated, poorly tolerated, or not effective, intravenous iron preparations provide an alternative, enabling faster repletion of iron stores (Killip et al., 2019).

Addressing the underlying cause of anemia is equally important. If gastrointestinal bleeding is identified, appropriate interventions—including medical or surgical treatment—are necessary. For example, controlling bleeding sources, treating infections such as H. pylori, or managing malabsorption conditions are crucial steps. Nutritional counseling to improve dietary intake of iron-rich foods—such as red meats, leafy greens, and fortified cereals—is recommended. In severe cases, blood transfusions may be considered temporarily, especially if the patient exhibits hemodynamic instability or symptomatic anemia (WHO, 2011).

Follow-up includes monitoring hemoglobin, hematocrit, and iron parameters to assess treatment response. Once hemoglobin levels normalize, ongoing maintenance and prevention measures should be implemented, particularly in high-risk groups, to prevent recurrence of iron deficiency (Lewis et al., 2017).

Conclusion

Iron deficiency anemia in adults is a common yet preventable condition that requires a systematic approach to diagnosis and management. Recognizing characteristic signs and laboratory findings allows for an accurate diagnosis. Identifying underlying causes—whether due to blood loss, malabsorption, or nutritional deficiency—is essential for targeted treatment. In addition, effective iron repletion therapy and addressing causative factors are vital to restoring health and preventing recurrence. As reflected in the case of John Doe, a combination of clinical assessment and detailed investigations can facilitate comprehensive care, ultimately improving patient outcomes.
