Chronic Obstructive Pulmonary Disease (COPD)

What is COPD?

Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory condition characterised by persistent airflow limitation that makes breathing difficult. COPD encompasses several lung diseases, including chronic bronchitis and emphysema, which often coexist and share similar symptoms.


In COPD, the airways become narrowed and obstructed, making it difficult for air to flow in and out of the lungs. This obstruction is usually caused by:


  1. Chronic inflammation: Inflammation of the airways and lung tissue leads to swelling and mucus production, further narrowing the airways and obstructing airflow.

  2. Damage to lung tissue: Exposure to irritants such as cigarette smoke, air pollution, and occupational dusts and chemicals can damage the delicate air sacs (alveoli) in the lungs, reducing their elasticity and impairing their ability to inflate and deflate properly

Risk factors

- Smoking: Tobacco smoke is the leading cause of COPD, accounting for the majority of cases.

- Environmental exposure: Long-term exposure to indoor and outdoor air pollution, secondhand smoke, and occupational dusts and chemicals can increase the risk of COPD.

- Genetic factors: Genetic predisposition may play a role in the development of COPD, although the exact genetic mechanisms are not fully understood.

- Respiratory infections: Recurrent respiratory infections, especially during childhood, may increase the risk of developing COPD later in life.


Symptoms of COPD include:

- Chronic cough

- Excessive mucus production (sputum)

- Shortness of breath, especially with physical activity

- Wheezing

- Chest tightness or discomfort

- Fatigue

- Recurrent respiratory infections

Treatment options

Management of COPD typically involves a combination of medications, pulmonary rehabilitation, lifestyle modifications, and oxygen therapy, as well as avoiding exposure to respiratory irritants and pollutants. Smoking cessation is the most important step in preventing COPD and slowing its progression. Vaccinations against influenza and pneumonia are also recommended to reduce the risk of respiratory infections in individuals with COPD. Early diagnosis and comprehensive management are essential for optimising outcomes and improving quality of life for individuals living with COPD.

Can exercise help?

Exercise can be highly beneficial for managing COPD by: 


  1. Improving lung function: Regular exercise can help improve lung function and respiratory muscle strength, making it easier to breathe and increasing oxygen delivery to tissues.

  2. Increase exercise tolerance:  Exercise helps to improve cardiovascular fitness and endurance, allowing individuals with COPD to engage in physical activities for longer periods of time without experiencing significant fatigue or shortness of breath.

  3. Reduce symptoms: Exercise can help reduce symptoms of COPD, such as chronic cough, excessive mucus production, shortness of breath, and fatigue, by improving overall lung function and respiratory efficiency.

  4. Strengthen muscles: Strength training exercises target specific muscle groups, including the respiratory muscles, helping to improve muscle strength and endurance, reduce muscle fatigue, and enhance functional abilities.

  5. Enhance quality of life: Regular exercise has been shown to improve overall well-being, increase energy levels, reduce anxiety and depression, and promote a sense of independence and empowerment, enhancing quality of life for individuals living with COPD.

  6. Reduce risk of complications: Exercise helps to reduce the risk of complications associated with COPD, such as respiratory infections, exacerbations (flare-ups) of symptoms, and hospitalizations, by improving overall health and immune function.

  7. Promote social interaction: Participating in group exercise programs or pulmonary rehabilitation can provide opportunities for social interaction, support, and encouragement from peers, which can be beneficial for individuals with COPD.
