Treatment of Functional Fatigue Syndromes in Men

Introduction to Treatment Options

• The American College of Physicians and other medical societies recommend a multimodal approach combining physical activity interventions, psychoeducational therapies, and cognitive-behavioral therapy as the primary treatment strategy for men with functional fatigue syndromes, while avoiding medications that lack evidence of benefit 1, 2

Initial Assessment and Diagnosis

• Functional fatigue syndromes include conditions like chronic fatigue syndrome (CFS), myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), and chronic multisymptom illness (CMI), and regular assessment of fatigue severity, impact, and coping strategies should be incorporated into clinical consultations 1
• Assessment should evaluate contributing factors including stress, sleep quality, comorbid conditions, physical activity levels, and mood, with the European League Against Rheumatism recommending a comprehensive assessment 3

Evidence-Based Non-Pharmacological Interventions

• Physical exercise has demonstrated effectiveness for reducing fatigue and improving quality of life in patients with functional fatigue syndromes, with the National Comprehensive Cancer Network recommending gradually introducing physical activity with individualized programs based on current conditioning level 1, 2, 5
• Specific beneficial activities include strengthening exercises, aerobic exercise, yoga, or tai chi, which have demonstrated significant improvements in physical functioning, quality of life, pain, fatigue, and sleep quality 1, 2
• Cognitive-behavioral therapy (CBT) should be offered as it has demonstrated moderate improvements in fatigue, distress, cognitive symptoms, and mental health functioning, with the American Psychological Association recommending CBT as a first-line treatment 1, 2

Medications to Avoid

• The American College of Physicians recommends avoiding corticosteroids, antivirals, and antibiotics as they have shown no benefit, and stimulants should not be used for fatigue symptoms 1, 2
• Opioids and NSAIDs are not recommended for chronic pain related to functional fatigue syndromes, and selective serotonin reuptake inhibitors (SSRIs) should be avoided specifically for symptoms of irritable bowel syndrome that may accompany functional fatigue syndromes 1, 2

Monitoring and Follow-up

• Regular monitoring of fatigue levels is essential as part of clinical care, with the European League Against Rheumatism recommending regular assessment of fatigue severity and impact 3, 4
• Develop an individualized treatment plan based on the patient's specific symptoms, goals, and preferences, with the American College of Physicians recommending shared decision-making between the patient and healthcare providers 1, 2, 3, 4
