Chronic obstructive pulmonary disease (COPD) is the name for a collection of lung diseases including chronic bronchitis, emphysema and chronic obstructive airways disease.
People with COPD have difficulties breathing, primarily due to the narrowing of their airways, this is called airflow obstruction.
Typical symptoms of COPD include:
- increasing breathlessness when active
- a persistent cough with phlegm
- frequent chest infections

Why does COPD happen?
The main cause of COPD is smoking. The likelihood of developing COPD increases the more you smoke and the longer you’ve been smoking. This is because smoking irritates and inflames the lungs, which results in scarring.
Over many years, the inflammation leads to permanent changes in the lung. The walls of the airways thicken and more mucus is produced. Damage to the delicate walls of the air sacs in the lungs causes emphysema and the lungs lose their normal elasticity. The smaller airways also become scarred and narrowed. These changes cause the symptoms of breathlessness, cough and phlegm associated with COPD.
Some cases of COPD are caused by fumes, dust, air pollution and genetic disorders, but these are rarer.

Who is affected?
COPD is one of the most common respiratory diseases in the UK. It usually affects people over the age of 35, although most people are not diagnosed until they are in their fifties.
It is thought there are over 3 million people living with the disease in the UK, of which only about 900,000 have been diagnosed. This is because many people who develop symptoms of COPD do not get medical help because they often dismiss their symptoms as a ‘smoker’s cough’.
COPD affects more men than women, although rates in women are increasing.
It is important that COPD is diagnosed as early as possible so treatment can be used to try to slow down the deterioration of your lungs. You should see your GP if you have any of the symptoms mentioned above.
COPD is usually diagnosed after a consultation with your doctor, which may be followed by breathing tests.

Although the damage that has already occurred to your lungs cannot be reversed, you can slow down the progression of the disease. Stopping smoking is particularly effective at doing this.
Treatments for COPD usually involve relieving the symptoms with medication, for example by using an inhaler to make breathing easier.
Surgery is only an option for a small number of people with COPD.

Living with COPD
COPD can affect your life in many ways, but help is available to reduce its impact.
Simple steps such as keeping healthy, being as active as possible, learning breathing techniques, and taking your medication can help you to reduce the symptoms of COPD.
Financial support and advice about relationships and end of life care is also available for people with COPD.

Whether it’s a short course of antibiotics to treat a mild infection, or a permanent supply of oxygen to help you to breathe, most lung conditions require treatment in some form or another.
This section provides information on the following types of treatments:
- Complementary therapies – everything from acupuncture to tai chi
- Lung transplantation – the replacement of one or both diseased lungs with the healthy lungs of a donor
- Lung volume reduction surgery – the removal of the damaged air spaces of the lung so that healthy parts can inflate and work better
- Nebulisers – a powerful drug delivery system to get medication into the lungs effectively
- Non-invasive ventilation – treatment to get oxygen into the lungs via a ventilator and a face mask
- Oxygen – used to correct a low oxygen level in the blood and help to ease breathlessness
- Pulmonary rehabilitation – a programme of physical exercise and advice on lung health
- Steroids – medication prescribed in oral or inhaled form, used to treat a number of different conditions
- Antibiotics – medication used to treat infections caused by bacteria
