What is the best approach to managing fatigue?

Managing Fatigue: A Comprehensive Approach

The best approach to managing fatigue is a systematic assessment followed by targeted interventions including physical activity, cognitive behavioral therapy, and treatment of underlying conditions, tailored to the specific type and cause of fatigue. 1, 2

Initial Assessment and Classification

Fatigue should be systematically assessed to determine its type and underlying causes:

• Physiologic fatigue: Normal response to physical or mental exertion
• Secondary fatigue: Related to underlying medical conditions
• Chronic fatigue: Persistent fatigue lasting >6 months, including ME/CFS

Key assessment components:

• Fatigue severity and impact on daily functioning
• Presence of post-exertional malaise (hallmark of ME/CFS)
• Sleep quality and patterns
• Comorbid conditions (pain, depression, anxiety)
• Medication review for fatigue-inducing drugs
• Disease activity in those with inflammatory conditions

Management Algorithm

Step 1: Address Underlying Causes

• Treat active disease: In inflammatory conditions, optimize disease control 1
• Manage comorbidities: Address anemia, sleep disorders, depression, anxiety
• Medication review: Adjust medications that may contribute to fatigue

Step 2: Non-Pharmacological Interventions

For Most Fatigue Types:

• Physical activity interventions:

  • Tailored exercise programs combining aerobic and resistance training
  • For inflammatory rheumatic conditions: Structured physical activity programs 1
  • For cancer survivors: Combined aerobic and resistance training 1
  • CAUTION: Avoid graded exercise therapy in ME/CFS as it may worsen symptoms 2

• Cognitive-behavioral therapy (CBT):

  • First-line treatment for chronic fatigue syndrome 2
  • Effective for cancer-related fatigue 1
  • Addresses activity pacing, sleep hygiene, and cognitive factors

• Mindfulness-based interventions:

  • Recommended for chronic fatigue and cancer-related fatigue 1, 2
  • Helps manage stress and emotional responses to fatigue

Disease-Specific Approaches:

• Cancer-related fatigue:

  • Energy conservation strategies
  • Limit naps to 1 hour to preserve nighttime sleep 1
  • American ginseng during active treatment 1
  • Acupressure for post-treatment fatigue 1

• Inflammatory bowel disease:

  • Systematic identification of severe fatigue
  • Address both inflammatory and non-inflammatory factors 1

• ME/CFS:

  • Activity pacing to avoid post-exertional malaise
  • Referral to specialists with ME/CFS expertise 2

Step 3: Pharmacological Interventions

• For pain-predominant fatigue:

  • Consider SNRIs and pregabalin 2
  • Avoid long-term NSAIDs and opioids

• For cancer-related fatigue:

  • Psychostimulants (methylphenidate) after ruling out other causes 1

• NOT recommended:

  • Stimulants for general fatigue
  • Corticosteroids, antivirals, or antibiotics for ME/CFS 2

Implementation Strategies

• Regular monitoring: Schedule follow-up visits to assess fatigue over time 1, 3
• Shared decision-making: Collaborate with patients on management plans 1
• Digital interventions: Consider web-based versions of effective programs for increased accessibility 1

Common Pitfalls to Avoid

• Dismissing fatigue as merely a symptom rather than a condition requiring specific management
• Over-attributing fatigue to psychological factors without thorough medical evaluation
• Recommending increased exercise for all fatigue types (dangerous in ME/CFS)
• Focusing only on disease activity in inflammatory conditions while ignoring other contributing factors
• Failing to reassess fatigue management strategies regularly

By systematically assessing fatigue, addressing underlying causes, and implementing targeted interventions, clinicians can significantly improve quality of life and functional outcomes for patients experiencing fatigue.
