Diagnosis
A healthcare professional will ask about your symptoms, how they change over time, and about your COVID history. There is no single test.
Tests that may be done
- Blood tests to look for inflammation or other problems
- A chest X-ray if you have breathing problems
- Checking your oxygen level with a small device on your finger
What to expect at your appointment
The doctor may suggest you keep a symptom diary. They might rule out other conditions with similar symptoms, such as anaemia or a thyroid problem. If needed, they will refer you to a specialist clinic.
Treatment
Treatment focuses on helping your body recover and controlling symptoms. It is tailored to you because everyone has different symptoms.
Self-care at home
- Pace yourself: do a little, then rest
- Sleep at regular times
- Slowly build up activity only when you feel ready
- Drink enough fluids
- Eat simple, nourishing meals
Medical treatments
Your doctor may suggest medicine for pain, breathing exercises, physiotherapy, or talking therapies to help you cope. They will not give you unnecessary medicines, and they will explain each option clearly.
When is surgery considered?
Surgery is not part of the usual treatment for COVID recovery. It is only considered if tests reveal a separate problem that needs an operation.
Living with this condition
Plan your days around your energy. If you have a busy day, schedule rest afterwards. Learn to say no without guilt.
Lifestyle tips
- Use a symptom diary to spot what makes things worse
- Try relaxation or breathing exercises
- Limit alcohol and caffeine
- Keep in touch with friends, even by phone
Diet and exercise
Eat a balanced diet with protein, vegetables and plenty of water. Gentle exercise like stretching, walking, or yoga can help, but stop if it makes you feel breathless or very tired.
Mental health and emotional wellbeing
Dealing with ups and downs can bring anxiety or low mood. These feelings are a normal response to feeling unwell for a long time.
Prevention
You cannot fully prevent COVID recovery from coming and going, but you can reduce the risk of getting COVID in the first place by washing your hands, wearing a mask in crowded places, and staying up to date with vaccines.
Vaccines
COVID vaccines lower the risk of severe illness. They may also reduce the chance of long COVID. Ask your local health provider about vaccination.
Screening programmes
There is no routine screening test for long COVID. Doctors diagnose it by your symptoms and history.
Complications
If left untreated
- Pushing through symptoms can keep you feeling worse for longer
- You may find it harder to return to work or school
- Your mental health may suffer if you feel unsupported
Long-term outlook
For most people, COVID symptoms continue to improve over weeks to months, even if they come and go. Ups and downs do not mean you are getting worse permanently. With good support and pacing, many people return to their usual lives.
