COPD that comes and goes

Overview

COPD that comes and goes is a pattern of chronic obstructive pulmonary disease (COPD) where your breathing symptoms get worse at times (flare-ups) and better at other times. It is not a separate disease, but many people with COPD experience this up-and-down pattern, sometimes called 'COPD with reversibility' or 'Asthma-COPD overlap' if you also have asthma-like features.

Yes, it is common. Many people with COPD have periods when their breathing is worse followed by times when it feels better. This pattern is especially common in people who also have asthma.

It mainly affects adults over the age of 40, particularly those who have smoked or had long-term exposure to lung irritants like dust, fumes, or secondhand smoke. People with a history of asthma can also develop this pattern.

Symptoms

Common symptoms

• Shortness of breath, especially during physical activity
• Wheezing or a whistling sound when you breathe
• Chest tightness that comes and goes
• A chronic cough that may produce mucus (sputum) – the amount and color can change during flare-ups
• Fatigue and feeling more tired than usual

Symptoms in children

• COPD does not usually affect children. However, children with asthma can have similar symptoms that come and go, such as coughing, wheezing, and shortness of breath, especially at night or after exercise.

Symptoms in older adults

• In older adults, the same common symptoms may be more pronounced, and flare-ups can cause confusion, drowsiness, or a blue tint to the lips or fingernails due to low oxygen levels.

Causes

Main causes

• Smoking (active or secondhand) – the most common cause
• Long-term exposure to lung irritants such as air pollution, chemical fumes, or dust at work
• A rare genetic condition called alpha-1 antitrypsin deficiency, which can cause lung damage

Risk factors

• Age over 40
• Having asthma or a history of frequent lung infections as a child
• Family history of COPD or alpha-1 antitrypsin deficiency
• Being around lung irritants for many years

When to see a doctor

See a doctor urgently if:

• You have emergency symptoms listed above
• Your usual treatment is not helping, and you feel worse day by day

Book a routine appointment if:

• You have a persistent cough, mucus, or shortness of breath that interferes with your daily activities
• You suspect you might have COPD and want a diagnosis
• You need a review of your treatment plan or a 'lung health check'

Diagnosis

Your doctor will ask about your symptoms, medical history, and smoking history, then perform a simple breathing test called spirometry to measure how well your lungs work.

Tests that may be done

• Spirometry – you blow into a machine as hard as you can
• Chest X-ray – to rule out other lung problems
• Blood tests – to check for infections or the genetic form of COPD
• Sometimes a CT scan or a test that measures oxygen levels in your blood

What to expect at your appointment

The diagnosis is usually straightforward and painless. You may be asked to stop using your inhaler for a few hours before the test. The results help your doctor understand your lung function and choose the best treatment for you.

Treatment

There is no cure for COPD, but treatment can help control symptoms, reduce the number of flare-ups, and improve your quality of life. Treatment is tailored to your needs and may include medications, breathing exercises, and lifestyle changes.

Self-care at home

• Quit smoking – this is the single most important step
• Avoid triggers like smoke, dust, strong fumes, and cold air
• Practice breathing techniques (such as pursed-lip breathing) during flare-ups
• Stay active with gentle daily movement, like walking
• Get vaccinated against flu and pneumonia every year

Medical treatments

Your doctor may prescribe inhalers that help open your airways (bronchodilators) or reduce swelling and inflammation. Some people need combination inhalers that do both. Inhaled treatments are usually the first step. For more advanced COPD, pulmonary rehabilitation (a supervised programme of exercise and education) can be very helpful. Oxygen therapy may be recommended if your blood oxygen levels are low. Never change or stop your medications without speaking to your doctor.

When is surgery considered?

Surgery for COPD is rare. In very severe cases, procedures like lung volume reduction or lung transplant may be considered by a specialist team. These options are only for a small number of people when other treatments are no longer effective.

Living with this condition

Living with COPD that comes and goes means being prepared for changes. Keep a written action plan from your doctor that tells you what to do when symptoms worsen. Monitor your symptoms and know your 'usual' breathing so you can spot a flare-up early.

Lifestyle tips

• Avoid smoking and stay away from smoke or polluted areas
• Learn energy-saving techniques, like sitting while cooking or dressing
• Practice stress management – anxiety can make breathlessness worse
• Use a peak flow meter or symptom diary to track your ups and downs

Diet and exercise

Eat a balanced diet with plenty of fruits and vegetables to keep your immune system strong. Stay hydrated to help thin mucus. Gentle exercise, like walking or water aerobics, can build your stamina. Pulmonary rehabilitation is a great way to learn safe exercises.

Mental health and emotional wellbeing

Anxiety and depression are common in COPD because breathlessness can be frightening and limiting. It is important to talk to your healthcare team about how you are feeling. They can offer support, counselling, or connect you with a mental health professional.

Prevention

Not all cases of COPD can be prevented, but you can lower your risk by not smoking, avoiding indoor and outdoor air pollution, and using protective equipment if you work with lung irritants. If you have asthma, keeping it well-controlled can also help.

Vaccines

Yes. Annual flu vaccines and a one-time pneumonia vaccine (plus booster if needed) are strongly recommended for people with COPD to help prevent infections that can trigger flare-ups.

Screening programmes

Screening spirometry is not recommended for the general public. However, if you have chronic symptoms or risk factors (like smoking or occupational exposure), your doctor may suggest a lung function test to detect COPD early.

Complications

If left untreated

• More frequent and severe flare-ups that may require hospital stays
• Progressive lung damage that makes it harder to breathe over time
• Increased risk of heart problems, lung infections, and high blood pressure in the lungs
• Loss of muscle strength, mobility, and independence
• Anxiety and depression that can worsen your overall health

Long-term outlook

With good management, many people with COPD that comes and goes lead active and fulfilling lives. Flare-ups can often be treated or even prevented. While the condition is serious and progressive, the right care can slow its progress and help you feel better day to day. Be hopeful – treatments and support are always improving.
