COVID recovery X ray explained

Overview

A chest X-ray after COVID-19 is a picture of your lungs and heart, taken to see how well your lungs are healing after an infection. It can show signs of inflammation, scarring, or other changes that may explain ongoing symptoms like a cough or breathlessness.

It is common for people who had moderate or severe COVID-19, or who were admitted to hospital, to have a chest X-ray during their recovery. People with mild COVID-19 usually do not need one unless they have persistent symptoms.

It may be recommended for anyone recovering from COVID-19 who has ongoing lung symptoms, underlying health conditions, or was seriously ill. Most people with mild illness will not need this test.

Symptoms

Common symptoms

• Persistent cough
• Shortness of breath
• Chest discomfort
• Feeling tired or weak

Symptoms in children

• In children, symptoms may include a lingering cough, fast breathing, or feeling unusually tired.
• Most children recover quickly and do not need a chest X-ray.

Symptoms in older adults

• Older adults may notice increased breathlessness, confusion, or a general decline in their usual activity level.
• Even a fall in energy or mobility can be a sign that the lungs need checking.

Causes

Main causes

• Inflammation of the lung tissue from the viral infection
• Scarring of the lungs, known as fibrosis, which may develop after severe pneumonia
• Fluid build up in the lungs, sometimes due to heart strain during the illness

Risk factors

• Severe COVID-19 illness
• Being older
• Having existing lung conditions such as asthma, COPD, or bronchiectasis
• Smoking or vaping
• Weakened immune system

When to see a doctor

See a doctor urgently if:

• If your breathlessness or cough is getting worse day by day
• If you develop new chest pain
• If you feel faint or confused

Book a routine appointment if:

• If you still have a cough or breathlessness more than four weeks after recovering from COVID-19
• If your exercise tolerance has not returned to normal
• If you were hospitalised with COVID-19 and have not yet had a follow-up appointment

Diagnosis

A chest X-ray is a diagnostic imaging test. Your doctor will first ask about your symptoms, listen to your lungs with a stethoscope, and check your oxygen levels. If they feel it is needed, they will arrange for a chest X-ray to look at the structures inside your chest.

Tests that may be done

• Chest X-ray
• Blood tests to check for inflammation or oxygen carrying capacity
• Oxygen saturation monitoring, using a small sensor on your finger
• Breathing tests, called spirometry, to measure lung function (sometimes)

What to expect at your appointment

You will stand in front of an X-ray machine and take a few deep breaths. The radiographer will ask you to stay still for a few seconds while the picture is taken. It usually takes less than 15 minutes. There is no special preparation and you can go home straight afterwards.

Treatment

There is no specific medication to 'fix' a post-COVID X-ray finding. Treatment focuses on helping your lungs heal and managing your symptoms. Your doctor will use the X-ray findings to guide your care, such as deciding if you need breathing support, pulmonary rehabilitation, or monitoring.

Self-care at home

• Rest and pace yourself – allow your body time to recover gradually
• Try simple breathing techniques, like slow, gentle breaths in and out
• Stay well hydrated
• Avoid smoking and second-hand smoke
• Return to exercise slowly, such as short walks, and stop if you feel breathless

Medical treatments

If your X-ray shows inflammation or infection, your doctor may treat the underlying cause, for example with antibiotics only if there is a bacterial infection. For breathing problems, they may suggest inhaled bronchodilators or steroid inhalers to help open the airways. If there is heart involvement, a specialist will guide treatment. Your doctor will always explain the options and risks.

Living with this condition

Recovery from COVID-19 can be slow. Listen to your body and don't try to push yourself back to normal too quickly. Set small goals, such as walking to the end of the street, and gradually increase your activity.

Lifestyle tips

• Get enough sleep and avoid heavy meals close to bedtime
• Reduce stress with relaxation, mindfulness, or talking to friends
• Avoid air pollution and dusty environments if they make you cough

Diet and exercise

Eat a balanced diet with plenty of fruits, vegetables, whole grains, and protein. Gentle exercise, such as walking or cycling, can help strengthen your lungs and heart. Stop if you feel dizzy or very short of breath and talk to your doctor.

Mental health and emotional wellbeing

Recovering from COVID-19 can be worrying, especially if you still feel unwell. It is normal to feel anxious or low. If these feelings persist, talk to your GP or a counsellor. Your feelings are just as important as your physical health.

Prevention

You can reduce the chance of severe lung damage from COVID-19 by protecting yourself against the virus and looking after your general health. Not smoking, staying active, and managing conditions like diabetes and high blood pressure all help your lungs recover more quickly.

Vaccines

COVID-19 vaccines make it much less likely you will get severe COVID-19, which in turn reduces the risk of lung damage and long-term breathing problems. Ask your healthcare provider about booster recommendations.

Complications

If left untreated

• If ongoing lung problems are not assessed, underlying issues such as scarring or heart problems might go unnoticed for longer.
• Ignoring sudden worsening symptoms like severe breathlessness or chest pain can lead to dangerous delays in urgent care.

Long-term outlook

Most people who recover from COVID-19 improve significantly over time. Even when an X-ray shows changes, many of these are temporary and get better with care, time, and healthy habits. Your doctor will work with you to plan the next steps, and you are not alone on this journey.
