Questions for Students: 1. What are the common signs and symptoms of iron deficiency anemia? 2. Explain the laboratory findings in John Doe's case and how they support the diagnosis of iron deficiency anemia. 3. What are the potential causes of iron deficiency anemia in adults, and how would you approach further investigations in this patient? 4. Discuss the treatment options for iron deficiency anemia, including dietary recommendations and pharmacological interventions.

Iron deficiency anemia manifests in multiple symptoms. Fatigue, shortness of breath, angina, and tachycardia are common symptoms of iron deficiency anemia (Kumar et al., 2022). The reduced blood oxygen levels cause chest pains and tachycardia. One could also have reduced intestinal blood flow due to the resultant hypoxemia, causing abdominal pain, weight loss, and nausea (Kumar et al., 2022). Insufficient blood levels also result in brittle nails and pale skin. Therefore, the symptoms the patient presented with, such as fatigue, shortness of breath, pale skin, and chest exertion, suggest the condition.

The patient's blood components are off the normal levels. His hemoglobin is below the normal range. Low hemoglobin levels are a significant indicator of iron deficiency anemia (Kumar et al., 2022). The patient's hematocrit, ferritin, Mean Corpuscular Volume (MCV), and serum iron levels are also low, suggesting iron deficiency anemia. However, the Total Iron Binding Capacity (TIBC) is high, a condition common in iron deficiency anemia, due to the body's increased attempt to transport iron. MCV is useful for differential diagnosis between anemias because it determines the average size of the red blood cells.

Like the patient, iron deficiency anemia could result from multiple factors in adults. First, iron is dependent on dietary intake (Kumar et al., 2022). Therefore, poor nutrition and consuming foods low in iron are potential causes of the condition. Still, menstruation may cause the condition; thus, women of reproductive age are high-risk. Additionally, digestive system problems, such as malabsorption, can cause iron deficiency anemia when the body cannot absorb enough iron. Gastrointestinal conditions like hemorrhoids and ulcers capable of causing gastrointestinal bleeding could also contribute to the condition. Inquiring about the patient’s iron intake can help understand contributing factors. Furthermore, a fecal occult blood test is important because a positive result indicates bleeding somewhere in the gastrointestinal tract, leading to chronic blood loss and anemia. Follow-up investigations, such as endoscopy or imaging, may be warranted based on these findings (Belali, 2022).

Dietary changes to incorporate iron-rich foods are primary in management. A healthy diet includes about 1–5 mg of heme iron and 5 to 10 mg of elemental iron, with sources such as leafy greens (broccoli, kale), red peppers, beans, lentils, and lean meats. Fruits high in vitamin C, like oranges, strawberries, and kiwi, aid in iron absorption. Pharmacological treatment involves oral ferrous sulfate, fumarate, or gluconate, with the option of parenteral iron if oral therapy fails or is contraindicated (Kumar et al., 2022). Side effects of oral iron include dark stools, constipation, metallic taste, and gastrointestinal upset, which should be communicated to the patient (Belali, 2022). Overall, management should be tailored to the underlying cause and patient response, emphasizing both diet and supplementation to restore iron stores.

Identifying and managing iron deficiency anemia requires a comprehensive understanding of its pathophysiology, clinical presentation, and tailored treatment strategies. This case study highlights the approach to diagnosing a 35-year-old male construction worker presenting with symptoms typical of anemia, supported by laboratory findings indicative of iron deficiency.

The clinical presentation of iron deficiency anemia often involves fatigue, pallor, shortness of breath, and sometimes angina or tachycardia, which result from reduced oxygen-carrying capacity of the blood (Kumar et al., 2022). In this case, the patient’s complaints of fatigue and pallor, combined with physical signs such as pale conjunctiva and skin, strongly suggest anemia. The laboratory investigations confirm this diagnosis through low hemoglobin, hematocrit, serum iron, ferritin, and MCV levels—in addition to a high TIBC—highlighting iron deficiency as the underlying cause.

Understanding the laboratory parameters is essential. Hemoglobin and hematocrit are direct measures of red blood cell mass; their low levels confirm anemia (Kumar et al., 2022). Serum ferritin reflects iron stores and is decreased in iron deficiency anemia, while serum iron and MCV help differentiate microcytic anemia caused by iron deficiency from other anemia types. Elevated TIBC occurs as the body attempts to compensate for iron deficiency by increasing transferrin production (Belali, 2022). These findings collectively solidify the diagnosis and guide subsequent management.

The causes of iron deficiency in adults are multifaceted. Dietary inadequacy, particularly in individuals with poor nutrition or restrictive diets, is a primary factor. For this construction worker with no reported dietary deficiencies, gastrointestinal blood loss warrants suspicion. Conditions such as hemorrhoids, ulcers, or gastrointestinal malignancies can lead to chronic blood loss, a common cause of iron deficiency. Menstruating women are at higher risk, but in males, investigations into occult gastrointestinal bleeding become critical (Belali, 2022). A fecal occult blood test and endoscopic evaluations are indicated to identify sources of bleeding. Malabsorption syndromes, such as celiac disease, should also be considered in persistent cases (Kumar et al., 2022).

Management of iron deficiency anemia involves correcting the iron deficit and addressing underlying causes. Dietary modifications include increasing intake of iron-rich foods: heme sources like lean meat and plant sources such as leafy greens, beans, and lentils. Vitamin C-rich fruits enhance absorption, making dietary counseling essential (Kumar et al., 2022). Pharmacologically, oral iron supplements—ferrous sulfate, fumarate, or gluconate—are first-line therapies, with parenteral iron reserved for cases of malabsorption or intolerance. Patients should be informed about common side effects, including gastrointestinal discomfort and dark stools, to enhance adherence (Belali, 2022). Proper follow-up with repeat labs ensures treatment efficacy and iron repletion.

In conclusion, diagnosing and managing iron deficiency anemia involves a holistic approach—integrating clinical assessment, laboratory analysis, investigation of underlying etiology, and patient-centered treatment strategies. Addressing dietary habits and ensuring medication adherence are vital components to restore iron stores and improve patient quality of life. Ongoing research and clinical guidelines emphasize the importance of individualized care plans to optimize outcomes in patients with iron deficiency anemia (Kumar et al., 2022; Belali, 2022; Domino et al., 2010).
