Does COVID-19 cause fatigue?

Fighting an infection can increase the body’s demand for rest. Fever, disrupted sleep, reduced food or fluid intake, pain, and less activity can add to the feeling of exhaustion. Fatigue also has many other causes, including stress, anaemia, thyroid problems, depression, medication effects, and other infections. Feeling tired alone cannot determine whether COVID-19 is the cause.

Rest when your body asks for it, but change position and do gentle movement as you are able. Break essential tasks into smaller parts and prioritise food, fluids, and sleep. Avoid trying to catch up with strenuous activity after a better day; an even pace can be easier to tolerate. Check current local public-health guidance about testing and reducing contact with others if COVID-19 is possible.

Get urgent medical help for trouble breathing, chest pain or pressure, new confusion, inability to stay awake, or blue or grey lips. Contact a clinician promptly if fatigue is getting worse, prevents drinking or managing basic needs, or comes with concerning symptoms such as dizziness, palpitations, or persistent high fever.

Ask whether testing is appropriate, whether any regular medicine could be contributing to tiredness, and how to return to usual activity safely. Ask which symptoms would make fatigue more concerning in the context of your own health conditions.
