Overview

Fatigue is a common nonspecific symptom due to a wide range of etiologies.Patients often use this term to describe a range of issues like difficulty initiating activity ; decreased capacity to maintain activity ; Trouble with concentration, memory, and emotional stability; or sleepiness or an uncontrollable need to sleep. The term fatigue can sometimes be used synonymously with Tiredness. Fatigue can present alone as a primary symptom or in association with other localizing symptoms.

Diagnosis

The approach to diagnosis of fatigue is based on a step-wise testing strategy. Below is an algorithm summarising the identification and laboratory diagnosis of fatigue.

• Diagnostic evaluation of fatigue when it presents as a predominant symptom includes a detailed history and physical examination, basic laboratory studies, and updated cancer screening interventions.
• Additional diagnostic testing depends on associated localized findings.
• Extensive laboratory studies with out a suggestive history or physical exam findings is of limited diagnostic utility while evaluating chronic fatigue.

Seek proper history, ask patients to describe in their own words, what do they mean by fatigue? This will help distinguish fatigue from ❑ somnolence ❑ muscle weakness The history should also determine the characteristics, severity, and temporal pattern of fatigue: ❑ Onset – Abrupt or gradual, relationship to illness or life event ❑ Course – Stable, improving, or worsening ❑ Duration and daily pattern ❑ Factors that alleviate or exacerbate it ❑ Impact on daily life – Ability to work, socialize, participate in family activities ❑ Accommodations that the patient/family has had to make to deal with symptom

Initial workup for hemolysis: ❑ Indirect bilirubin ❑ serum haptoglobin ❑ Lactate dehydrogenase level ❑ Reticulocyte count ❑ Urinalysis
