What to expect from a GP consultation for chronic fatigue syndrome

The GP may ask when the fatigue began, how it affects work or study, whether activity causes a delayed worsening, and how you sleep and recover. They may ask about pain, dizziness, concentration, mood, appetite, medicines and recent infections. Examination can include observations and checks of the heart, lungs, neurological function and general health. Blood or urine tests may be considered when they could identify another explanation, such as anaemia, thyroid problems or infection; testing is tailored to your history.

Before the appointment, note your daily energy pattern, activities that trigger a setback, sleep changes, symptoms that occur together and any medicines or supplements. Bring a short timeline and, if possible, someone who has seen how symptoms affect you. Describe what you can do on a typical day rather than only your best day. Ask how to pace activity without repeatedly exceeding your limits, what support is available, and when the plan will be reviewed. A follow-up may be useful because symptoms and capacity can change.

Seek urgent medical help for new chest pain, severe breathlessness, fainting, sudden weakness, confusion, or thoughts of harming yourself. Arrange prompt review if fatigue is rapidly worsening, you are losing weight without trying, have persistent fever, unusual bleeding or a new neurological symptom. These features need assessment on their own and should not be attributed to chronic fatigue syndrome without checking.

What other causes of fatigue should we check? How can I recognise post-exertional worsening? Which activities should I pace first? What support can help with work, study or daily tasks? When should we review the plan?
