Study Notes

Fatigue

A frequent symptom in primary care that can disrupt a patient's life, especially when persistent and unexplained.
Fatigue can be a sign of a wide range of underlying conditions.

Systemic Intolerance Disease (Chronic Fatigue Syndrome)

A chronic medical condition characterized by persistent and debilitating fatigue, which is not relieved by rest.
Other symptoms include: cognitive impairment, sleep problems, muscle and joint pain, and post-exertional malaise.
The exact cause is unknown but is thought to be related to a combination of factors including genetics, immunologic disorders, and environmental triggers.

History Taking and Physical Examination

Key to identifying underlying causes of fatigue and ruling out serious medical conditions.
A thorough assessment should include medical, social and sleep history, as well as a review of systems.
Should address potential "red flags" such as weight loss, fever, night sweats, and lymph node enlargement.

Differential Diagnosis

Consider medical, psychological, psychiatric, sleep, medication, and lifestyle factors.
Psychological and psychosocial causes of fatigue are extremely common.
Sleep disorders may be a factor in fatigue.
Medication side effects can cause tiredness.
Lifestyle factors such as diet, exercise, and stress levels can contribute to fatigue.

Laboratory and Diagnostic Tests

Used to confirm suspected causes of fatigue and rule out other medical conditions.
Common tests include: blood tests (CBC, thyroid function, vitamin D, B12), urinalysis, and imaging studies.
Electrodiagnostic tests can help determine the presence of nerve disorders.

Treatment and Management

Management of fatigue often depends on the underlying cause and is multifaceted.
Involves supportive care, education, lifestyle modifications, and psychotherapy, when appropriate.
Medication may be used to manage specific symptoms.
SEID is a rare cause of fatigue and other explanations often need to be carefully excluded.

Prognosis

Recovery from SEID is unknown and there is no cure. Current treatments focus on managing symptoms.
Research is ongoing to understand the pathophysiology of SEID and develop more effective treatment options.
Factors such as severity of fatigue, symptom control, perception of root cause, and psychosocial management all play a role in prognosis.
Building a supportive and trusting relationship with healthcare professionals is vital for patients.
