10 Chronic Fatigue Syndrome (CFS/ME) Facts

Chronic fatigue syndrome (CFS) – or myalgic encephalomyelitis (ME) – is a complex and long-term illness characterized by extreme fatigue that worsens with physical or mental activity, a lack of rest, sleep problems, and issues with thinking and concentration.

1. Definition

  • Chronic Fatigue Syndrome (CFS/ME) is a complex, long-term illness characterized by profound fatigue that is not relieved by rest and interferes with daily life.

2. Cause

  • The exact cause of CFS/ME is unknown, but it is thought to involve a combination of factors including viral infections, immune system dysfunction, and stress.

3. Risk Factors

  • Risk factors include a history of viral infections (e.g. glandular fever), autoimmune conditions, and stress. It is more common in women and typically develops in the 30s-50s.

4. Symptoms

  • Key symptoms include persistent and profound fatigue, muscle pain, joint pain, headaches, sleep disturbances, and cognitive difficulties (e.g. memory and concentration problems).

5. Diagnosis

  • Diagnosis is clinical, based on symptoms and exclusion of other causes of fatigue. Common criteria include the Institute of Medicine (IOM) criteria, which require profound fatigue lasting ≥6 months, along with ≥1 other symptom (e.g., muscle pain, cognitive issues).

6. Treatment

  • Treatment focuses on symptom management and improving quality of life. This may include cognitive-behavioural therapy (CBT), graded exercise therapy (GET), pacing activities, and medications for pain and sleep disturbances.

7. Complications

  • Complications can include physical deconditioning, social isolation, depression, and reduced quality of life. Some patients may become housebound or bedridden.

8. Prognosis (outlook)

  • Prognosis varies; some patients recover over time, while others experience persistent symptoms. Early diagnosis and management can improve outcomes.

9. Prevention

  • There is no known way to prevent CFS/ME, but early recognition and management of symptoms may help reduce severity.

10. Referral

  • Refer unwell patients to a specialist with experience in CFS/ME for comprehensive management, particularly if symptoms are severe or not responding to initial treatment
  • Multidisciplinary care involving physiotherapy, psychology, and occupational therapy can be beneficial.
