Fatigue after COVID-19: what should you know?

Recovery can be uneven: a person may manage an activity one day and feel depleted later. Poor sleep, reduced appetite, low mood, breathlessness and loss of routine can add to fatigue. Do not assume every ongoing symptom is from COVID-19. Anaemia, thyroid problems, medication effects, dehydration, Chronic Kidney Disease and other conditions can also cause tiredness. Note whether exertion causes a delayed worsening, how long it lasts, and which symptoms occur with it.

Pace activity by breaking tasks into smaller periods and taking planned rests before exhaustion. Increase activity gradually only when your current level is manageable without a delayed flare. Keep regular sleep and meal routines, drink enough to avoid dark urine, and prioritise essential tasks. A clinician can review your recovery, breathing, mood, medicines and other possible causes; seek advice before pushing through marked worsening.

Seek urgent help for severe breathing difficulty, chest pain, fainting, new confusion, blue or grey lips, or sudden weakness. Arrange a medical review if fatigue is worsening, limits basic activities, prevents sleep, or comes with persistent fever, palpitations, significant weight change or low mood with thoughts of self-harm.

Could another condition or medicine be adding to my fatigue? How should I pace activity? What symptoms need urgent attention, and would tests help check anaemia, hydration or organ function?
