Chronic obstructive pulmonary disease is a long-term lung condition
that causes persistent airflow limitation through narrowed or damaged
airways.
COPD develops when chronic inflammation, airway narrowing and lung
damage make it harder to move air out of the lungs. Unlike the
variable airflow obstruction often seen in asthma, COPD airflow
limitation is usually persistent and may progress over time.
Emphysema and chronic bronchitis are the main forms of COPD. Many
people have features of both conditions, and some also have asthma,
bronchiectasis or another respiratory condition that affects their
symptoms and treatment.
Lung-tissue damage
Emphysema
The air sacs, or alveoli, become damaged. This reduces the
surface area available for oxygen to pass into the blood and
carbon dioxide to leave it.
Airway inflammation
Chronic bronchitis
The bronchi become inflamed and narrowed, with increased
mucus production that can cause persistent cough, phlegm and
recurrent chest infections.
Recognising COPD
What are the symptoms of COPD?
Symptoms usually develop gradually and may initially be noticed only
during exercise, hills or stairs.
Persistent cough
A long-term cough that may be dry or productive of mucus and
can be worse in the morning.
Shortness of breath
Breathlessness may first occur with activity and become more
limiting as COPD progresses.
Wheeze
A whistling or musical sound during breathing caused by
narrowing of the airways.
Phlegm production
Regular mucus production may occur, particularly in people
with chronic-bronchitis features.
Recurrent chest infections
Some people experience repeated infections or episodes needing
antibiotics, steroid tablets or hospital treatment.
Reduced stamina and fatigue
Breathlessness, poor sleep, muscle deconditioning and low
oxygen levels can reduce energy and activity.
Risk factors
What causes COPD?
COPD usually develops after long-term exposure to smoke, particles,
fumes or chemicals that repeatedly irritate and damage the lungs.
Most common cause
Smoking and inhaled tobacco smoke
Long-term cigarette, cigar, pipe or shisha smoking is the most
common cause. Risk is related to cumulative exposure, but not
every person who develops COPD has smoked.
Stopping smoking matters at every stage.
Quitting can reduce further lung-function decline and lower the
risk of exacerbations and other smoking-related disease.
Long-term exposure to dusts, vapours, chemicals or industrial
fumes can contribute to COPD.
Biomass-fuel smoke
Smoke from burning wood, charcoal, crop waste or other fuels in
poorly ventilated spaces is an important cause worldwide.
Alpha-1 antitrypsin deficiency
This inherited condition can cause emphysema, sometimes at a
younger age or with a limited smoking history.
Early-life lung development
Premature birth, childhood respiratory disease or impaired lung
growth may leave a lower reserve in adult life.
Specialist assessment
How is COPD diagnosed?
COPD diagnosis combines symptoms and exposure history with objective
lung-function testing. A scan or symptoms alone are not usually enough
to confirm the condition.
Clinical review
Understand the symptoms and exposure history
The assessment begins with breathlessness, cough, sputum,
wheeze, chest infections and exercise limitation. Smoking,
shisha use, biomass smoke and occupational exposure are reviewed
alongside previous diagnoses and treatment.
Pattern and duration of respiratory symptoms
Smoking and environmental exposure history
Frequency and severity of COPD flare-ups
Current inhalers and response to treatment
Heart, sleep and other medical conditions
Essential objective test
Confirm persistent airflow obstruction with spirometry
Spirometry measures how much air can be forcibly exhaled and how
quickly it leaves the lungs. COPD is supported when testing
shows persistent airflow obstruction in the appropriate
clinical context.
Normal flow-volume loop
Obstructive flow-volume loop
Illustrative comparison only. Individual loop size and
shape vary with age, height, sex, effort and disease
severity.
The obstructive loop typically has a reduced peak flow and
a concave, “scooped” expiratory limb.
COPD should not normally be diagnosed from symptoms or a
CT scan alone. Post-bronchodilator spirometry is used to
demonstrate persistent airflow obstruction.
Assess emphysema, chronic bronchitis and associated conditions
Further tests are selected according to symptoms, COPD severity,
sputum production, infection history, oxygen levels and whether
another condition may also be contributing.
What else could be causing breathlessness or cough?
Asthma, bronchiectasis, heart disease, pulmonary fibrosis, anaemia,
obesity, sleep apnoea, reflux and physical deconditioning may mimic or
coexist with COPD. Identifying these problems can significantly
change treatment.
Individualised management
How is COPD treated?
COPD cannot usually be cured, but treatment can reduce symptoms,
prevent flare-ups, maintain independence and slow further damage.
Treatment should target the person’s COPD pattern
Some people mainly experience breathlessness and emphysema. Others
produce regular mucus, develop infections or have frequent
exacerbations. Inhaler choice and additional treatment should
reflect these differences.
Daily symptom control
Inhaler therapy
Bronchodilator inhalers relax airway muscle and can reduce
breathlessness and wheeze. Some people also benefit from inhaled
corticosteroids when exacerbation history, eosinophils or asthma
features indicate likely benefit.
Inhaler technique, inspiratory flow and the ability to use the
device correctly should be reviewed regularly.
Flare-up management
Rescue treatment
A COPD action plan may include instructions for increasing
bronchodilator use and, when clinically appropriate, starting a
short course of oral corticosteroids or antibiotics.
Rescue medication should be prescribed with clear instructions
about when to use it and when to seek medical help.
Exercise and education
Pulmonary rehabilitation
Pulmonary rehabilitation combines supervised exercise with
education about breathlessness, pacing, medication, nutrition
and living with COPD.
It can improve exercise capacity, confidence and quality of life
even when lung-function measurements do not change.
Mucus management
Chest physiotherapy
Airway-clearance techniques can help people who produce regular
mucus or have difficulty expectorating. Physiotherapists can also
provide breathing-pattern and pacing advice.
The technique or device should be selected according to symptoms,
strength, sputum volume and coexisting disease.
Recurrent infection
Long-term antibiotic strategies
Selected patients with repeated exacerbations may benefit from
prophylactic antibiotics after sputum testing, ECG review and
optimisation of inhalers and airway clearance.
Benefits must be balanced against side effects, interactions and
antimicrobial resistance.
Preventing infection
Vaccinations
Vaccination status should be reviewed regularly. Recommended
vaccines depend on age, clinical risk, previous vaccination and
current national guidance.
Influenza, pneumococcal and other respiratory vaccines may be
relevant to an individual COPD care plan.
Low oxygen levels
Oxygen assessment
Oxygen is prescribed only after appropriate assessment. Some
people require oxygen during exertion, while a smaller group may
qualify for long-term oxygen therapy.
Breathlessness alone does not demonstrate that oxygen is needed;
oxygen levels and sometimes arterial blood gases must be checked.
Selected advanced COPD
Specialist interventions
Selected patients may be assessed for non-invasive ventilation,
lung-volume-reduction procedures, surgery, transplantation or
targeted biologic treatment.
Suitability depends on disease pattern, exacerbations, blood
results, imaging, fitness and previous treatment.
Ongoing self-management
Building a practical COPD care plan
Good long-term management combines medication with prevention,
exercise, monitoring and a clear plan for worsening symptoms.
01
Know your usual symptoms
Record your normal breathlessness, cough, sputum and activity so
that important changes are recognised early.
02
Use inhalers correctly
Follow the prescribed schedule, use a spacer when advised and have
technique checked regularly.
03
Remain physically active
Regular activity helps maintain muscle strength and reduces
deconditioning-related breathlessness.
04
Recognise flare-ups
Follow the written action plan and seek help when symptoms are
severe, unusual or fail to respond.
05
Reduce infection risk
Review vaccinations, hand hygiene, sputum management and exposure
to people with active respiratory infection.
Consultant respiratory expertise
Why see Dr Ricardo José for COPD?
COPD care should extend beyond confirming airflow obstruction and
prescribing an inhaler.

Common questions
COPD FAQs
Answers to common questions about diagnosis, progression, inhalers
and living with COPD.
Is COPD the same as asthma?
No. Both can cause cough, wheeze and airflow obstruction, but
COPD is usually linked to chronic exposure and persistent
airflow limitation. Asthma is often more variable. Some patients
have features of both, so clinical assessment and lung-function
testing are important.
Can COPD occur in someone who has never smoked?
Yes. Other causes include occupational dusts and fumes,
biomass-fuel smoke, impaired lung development and alpha-1
antitrypsin deficiency. Previous severe respiratory disease may
also contribute.
Can COPD be cured?
Existing structural lung damage cannot usually be reversed, but
treatment can reduce symptoms and flare-ups, improve activity and
slow further decline. Stopping smoking is particularly important.
How is COPD confirmed?
COPD is diagnosed using the clinical history, examination and
post-bronchodilator spirometry showing persistent airflow
obstruction. Imaging and additional tests may assess severity or
identify another condition.
Do all patients with COPD need a steroid inhaler?
No. Steroid inhalers are most useful in selected patients,
including some people with repeated exacerbations, raised
eosinophils or asthma features. Potential benefits must be
balanced against risks such as oral thrush, bruising and
pneumonia.
Does breathlessness mean I need oxygen?
Not necessarily. Breathlessness can occur despite normal oxygen
levels. Oxygen should be prescribed only after measuring oxygen
saturation and, when required, arterial blood gases or exercise
oxygen levels.
What should I do during a COPD flare-up?
Follow your written COPD action plan, use prescribed medication
as directed and seek medical advice if symptoms are severe,
unusual, worsening or not responding. Call 999 for emergency
warning signs.
Can pulmonary rehabilitation help severe COPD?
Yes. Pulmonary rehabilitation is often particularly valuable
when breathlessness has reduced activity. Programmes can be
adapted to different levels of fitness and mobility.
