Case Study: Iron Deficiency Anemia Patient Information:

• Name: John Doe • Age: 35 • Gender: Male • Occupation: Construction Worker • Medical History: No significant medical history reported.

Presenting Complaint: John Doe presents to the clinic with complaints of fatigue, weakness, and shortness of breath on exertion for the past few months. He reports feeling unusually tired, even after a full night’s sleep, and has noticed increased paleness of his skin and conjunctiva. Physical Examination Findings:

• Vital Signs: BP 120/80 mmHg, HR 80 bpm, RR 16 breaths/min, Temp 98.6°F • General: Pale skin and conjunctiva, fatigue apparent • Cardiovascular: Regular rhythm, no murmurs or abnormal sounds • Respiratory: Clear lung fields bilaterally • Abdomen: Soft, non-tender, no organomegaly • Neurological: Intact cranial nerves, normal motor and sensory functions

Laboratory Investigations:

• Hemoglobin (Hb): 9.5 g/dL (Normal range: 13.5-17.5 g/dL) • Hematocrit (Hct): 29% (Normal range: 40-50%) • Mean Corpuscular Volume (MCV): 75 fL (Normal range: 80-100 fL) • Serum Iron: 25 mcg/dL (Normal range: 60-170 mcg/dL) • Total Iron Binding Capacity (TIBC): 400 mcg/dL (Normal range: 250-450 mcg/dL) • Ferritin: 10 ng/mL (Normal range: 30-400 ng/mL)

Diagnosis: John Doe is diagnosed with iron deficiency anemia based on his clinical presentation, physical examination findings, and laboratory results. 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.

Step-by-Step Guide for Writing Your Case Study Response

Use this guide to structure your paper clearly, logically, and in a way that demonstrates strong clinical reasoning—exactly what your instructor is looking for.

How to Structure Your Paper

1. Introduction

Begin with a brief overview of the patient and the purpose of your case study.

Example structure:

Introduce John Doe (age, occupation).
State his presenting symptoms (fatigue, weakness, SOB on exertion).
Mention that the goal of this paper is to analyze signs/symptoms, interpret labs, explore causes, and discuss treatment of iron deficiency anemia.

2. Answer to Question 1: Common Signs & Symptoms of Iron Deficiency Anemia

In this section:

Start with a general explanation of iron deficiency anemia.
List common symptoms such as:
- Fatigue
- Weakness
- Pallor
- Shortness of breath
- Dizziness or lightheadedness
- Cold intolerance
- Brittle nails or hair loss
- Pica (craving non-food items)
Then connect these general symptoms to the specific symptoms John Doe presents with.

3. Answer to Question 2: Interpretation of Laboratory Findings

Organize your interpretation by lab result:

Use this approach:

Present each lab value.
State whether it is low or high.
Explain what that means in iron deficiency anemia.

Example breakdown:

Low Hemoglobin/Hematocrit: Indicates anemia.
Low MCV: Shows microcytic RBCs, characteristic of iron deficiency.
Low serum iron + high TIBC: Classic pattern of depleted iron stores; body increases binding capacity when iron is low.
Low ferritin: Most specific marker confirming iron deficiency.

End the section by summarizing why all labs together strongly support the diagnosis.

4. Answer to Question 3: Potential Causes & Further Investigations

Separate this section into two parts: (A) Possible causes, (B) Evaluation plan.

A. Possible Causes in Adults:
Include causes such as—

Chronic blood loss (GI bleeding, ulcers, colon cancer)
Dietary deficiency
Malabsorption (celiac disease)
Increased requirements (high physical exertion workers)
Parasite infections (less common in U.S.)

B. What to Investigate:
Recommend:

Stool occult blood test
Colonoscopy/upper endoscopy if bleeding suspected
Dietary assessment
Screening for malabsorption (e.g., celiac panel)

This shows strong clinical reasoning and aligns with what your instructor expects.

5. Answer to Question 4: Treatment Options

Divide into dietary and pharmacological interventions.

A. Dietary Recommendations:

Encourage iron-rich foods such as:

Red meat, poultry, fish
Beans, lentils, tofu
Dark leafy greens
Fortified cereals

Include the tutor-friendly reminder:

Vitamin C enhances absorption.
Calcium, tea, and coffee inhibit absorption.

B. Pharmacological Treatment:

Oral iron supplementation (ferrous sulfate, ferrous fumarate)
Recommended dosing (usually 150–200 mg elemental iron/day)
Side effects (GI upset, constipation)
Importance of adherence for several months to replenish stores
When IV iron is indicated (malabsorption, intolerance to oral iron, severe anemia)

Close by stating expected follow-up: repeat labs in 4–6 weeks.

6. Conclusion

Summarize key points:

John’s symptoms + labs confirm iron deficiency anemia.
Proper evaluation is essential to find the underlying cause.
Treatment includes both correcting the deficiency and addressing the root cause.
