How long can COVID fatigue last?

Fatigue may start during the infection and continue after fever, cough, or congestion have eased. Recovery can be uneven: a better day followed by a tiring day does not automatically mean you are getting worse. Sleep disruption, reduced nutrition, dehydration, stress, and returning to activity too quickly can all make energy feel lower.

If tiredness is prolonged, a clinician may consider other explanations such as [Anaemia](/conditions/anaemia/), [Chronic Kidney Disease](/conditions/chronic-kidney-disease/), [Coeliac Disease](/conditions/coeliac-disease/), [Burnout](/conditions/burnout/), or [Dehydration](/conditions/dehydration/).

Plan essential tasks for the part of the day when you have most energy. Alternate activity with rest, and reduce the task rather than repeatedly pushing until you crash. Keep meals, fluids, and sleep times as regular as possible. Add gentle movement in small amounts when tolerated, then watch how you feel later and the next day before increasing it. Tell work, school, or family what help you need.

Seek urgent help for severe breathlessness, chest pain, fainting, new confusion, inability to stay awake, or serious dehydration. Arrange a review if fatigue is worsening, stops you managing basic needs, returns with fever, or comes with palpitations, weakness, bleeding, or unexplained weight change. Your clinician can review ongoing [COVID-19](/conditions/covid-19/) symptoms and check other causes.

Ask what recovery pattern is reasonable for you, whether tests are appropriate, and how to increase activity safely. Bring a brief record of sleep, exertion, symptoms, food, and fluids, and mention mood changes, snoring, dizziness, breathlessness, or new medicines.
