COPD
Chronic Obstructive Pulmonary Disease is a progressive lung condition causing breathlessness, persistent cough, and frequent chest infections. While COPD cannot be cured, early diagnosis and the right treatment significantly slow its progression and improve quality of life.

What is COPD?
COPD is an umbrella term covering chronic bronchitis (persistent inflammation of the airways) and emphysema (damage to the air sacs in the lungs). Both result in obstructed airflow that worsens over time. Unlike asthma, the airflow limitation in COPD is not fully reversible.
COPD is significantly underdiagnosed — many people attribute their breathlessness to ageing or lack of fitness rather than seeking medical assessment. Early diagnosis through spirometry testing is essential to begin appropriate treatment before significant lung function is lost.
Symptoms
- Persistent breathlessness, initially on exertion and later at rest in advanced disease
- Chronic productive cough — often worse in the morning
- Frequent chest infections, especially in winter
- Wheezing and chest tightness
- Fatigue and reduced exercise tolerance
- In advanced COPD: weight loss, ankle swelling, and cyanosis (bluish lips or fingertips)
Causes & risk factors
- Cigarette smoking — responsible for approximately 90% of COPD cases
- Long-term exposure to occupational dust, chemicals, or indoor air pollution
- Childhood respiratory infections that impair lung development
- Genetic factors — alpha-1 antitrypsin deficiency causes COPD in non-smokers
When to see a doctor
See a doctor if you have a persistent cough, increasing breathlessness, or frequent chest infections — particularly if you are over 35 and a current or ex-smoker. The earlier COPD is diagnosed, the more effectively progression can be slowed.

Treatment options
- Smoking cessation — the single most effective intervention to slow COPD progression
- Bronchodilator inhalers (SABA, LABA, LAMA) — to open airways and reduce breathlessness
- Inhaled corticosteroids — added in moderate-severe disease to reduce exacerbations
- Pulmonary rehabilitation — structured exercise and education programme that significantly improves quality of life
- Vaccinations — annual flu and pneumococcal vaccines reduce the risk of serious infections
- Oxygen therapy — for patients with severely reduced oxygen levels
How eMedClinic can help
Our pulmonologists provide COPD assessments, prescribe and review inhaler regimens, and support smoking cessation. We also help patients who have moved abroad maintain continuity of their COPD treatment and adapt their management to life in a new climate and healthcare environment.
