iHuman Case Study: Fatigue in an Older Adult
Patient Name: Chana Kumar
Age: 86 years
Chief Complaint: “I feel tired all the time.”
🧠 1. Clinical Significance of Fatigue in the Elderly
Fatigue in older adults is never “just aging.” At 86, it’s often a sign of an underlying
systemic issue involving:
Oxygen delivery (anemia, heart failure)
Metabolic imbalance (thyroid, diabetes, renal)
Infection
Depression
Medication effects
In this age group, fatigue can be the only presenting symptom of serious disease.
📋 2. Focused History Questions
Category What to Ask Why It Matters
Onset Sudden or gradual? Sudden → infection, cardiac, anemia
Duration Days, weeks, months? Chronic vs acute condition
Sleep Sleeping well? Daytime naps? Sleep apnea, insomnia
Weight Weight loss/gain? Cancer, thyroid, CHF
Diet Appetite? Iron intake? Malnutrition, anemia

86yrs Old Female CC: Fatigue(class 6512)
2026 i human case
Category What to Ask Why It Matters
Mood Sadness, loss of interest? Depression common in elderly
Cardiac Chest pain, palpitations, swelling? Heart failure, arrhythmia
Respiratory Shortness of breath? COPD, pneumonia, anemia
Urinary Burning, frequency? UTI can present as fatigue only
Medications New meds? Polypharmacy? Sedatives, beta blockers cause fatigue
🧠 3. Physical Examination Focus
System Key Findings to Look For
General Pallor, frailty, dehydration
Vitals Fever, hypotension, tachycardia
Cardiovascular Murmur, edema, irregular pulse
Respiratory Crackles, reduced breath sounds
Thyroid Enlargement, tremor, dry skin
Neuro Confusion, weakness
Skin Bruising, jaundice, pressure sores
🧠 4. Priority Diagnostic Tests
Test Rationale
CBC Anemia, infection
CMP Electrolytes, kidney, liver function
, iHuman Case Study (NEW) - Chana Kumar -
86yrs Old Female CC: Fatigue(class 6512)
2026 i human case
Test Rationale
TSH & T4 Hypothyroidism
Blood glucose Diabetes
Urinalysis UTI
ECG Arrhythmias
BNP Heart failure
Vitamin B12 Deficiency fatigue
Iron studies Iron deficiency anemia
⚠️ 5. Most Likely Differential Diagnoses
Condition Why Suspected in Chana
Anemia Very common cause of fatigue in elderly
Heart Failure Poor oxygen delivery causes tiredness
Hypothyroidism Slows metabolism → fatigue
Depression Major geriatric fatigue cause
Chronic Kidney Disease Toxin buildup → weakness
Infection (UTI/Pneumonia) Often presents without fever in elderly
Medication Side Effect Sedatives, antihypertensives
🧠 6. Key Findings & Pathophysiology Link
