Extreme fatigue after COVID-19

Fatigue is more than feeling sleepy: it can affect concentration, movement, motivation, and the ability to manage routine tasks. During COVID-19, the immune response, poor sleep, fever, reduced food or fluid intake, and breathing symptoms may all contribute. Fatigue can linger after other symptoms improve, but a continuing or worsening problem has several possible explanations.

Other causes include [Dehydration](/conditions/dehydration/), [Anaemia](/conditions/anaemia/), [Chronic Kidney Disease](/conditions/chronic-kidney-disease/), [Coeliac Disease](/conditions/coeliac-disease/), or [Burnout](/conditions/burnout/). Fatigue is a symptom, not a diagnosis.

Break tasks into small parts and pause before you feel depleted. Keep a simple record of sleep, activity, meals, fluids, and symptoms to spot patterns. Choose gentle movement only when it does not worsen your symptoms later, and increase activity gradually. Ask someone you trust to help with meals, shopping, or childcare while energy is low. Regular food and fluids support recovery, unless a clinician has given you a restriction.

Seek urgent help for severe breathlessness, chest pain, fainting, new confusion, inability to stay awake, or signs of serious dehydration. Arrange a medical review if fatigue prevents basic self-care, suddenly worsens, comes with palpitations or bleeding, or fails to improve. A clinician can check for ongoing [COVID-19](/conditions/covid-19/) and other causes.

Ask what level of activity is suitable, whether you need blood or urine tests, and how to distinguish post-viral fatigue from another condition. Mention sleep quality, mood, appetite, breathlessness, dizziness, alcohol use, and any new medicines.
