Chronic Obstructive Pulmonary Disease, or COPD, is a long-term lung condition that makes it hard to breathe. It happens when the airways in the lungs become inflamed and narrowed, reducing the flow of air in and out. Many people with COPD do not even realise they have it, often thinking early signs like a persistent cough or shortness of breath are just part of getting older or the effects of smoking.
However, catching COPD in its early stages is critical because timely intervention can slow its progression, improve quality of life and reduce complications.
What is COPD?
COPD is a term for certain types of long-term lung conditions that cause airflow obstruction and make breathing difficult. The two main types of COPD are chronic bronchitis, a condition that causes airway irritation, constriction and mucus buildup, and emphysema, in which the lung’s air sacs are damaged, reducing their ability to exchange oxygen effectively.
Who is at risk of COPD?
Certain people are more likely to develop COPD due to lifestyle, environment or health factors:
- Smokers and ex-smokers: Around 85–90% of COPD cases are linked to cigarette use.
- Women: Recent studies show women are more vulnerable to lung damage from smoking than men.
- Older adults: Risk increases after age 65 due to accumulated lung damage.
- Occupational exposure: Individuals employed in settings with exposure to dust, chemical vapours or harmful fumes.
- Childhood infections: Severe respiratory infections early in life can weaken lung function.
What are the early COPD symptoms?
One of the dangers of COPD is that symptoms develop gradually, which often delays diagnosis. Early signs include a persistent cough with mucus, wheezing, shortness of breath during activity, frequent respiratory infections and unexplained fatigue. As the disease progresses, symptoms may worsen into chest tightness, weight loss, swelling in the legs and sudden flare-ups.
How is COPD diagnosed?
Doctors use a combination of medical history, physical exams and tests to diagnose the condition. Common methods include:
- Lung function test (spirometry): This measures how much air you can exhale and how quickly.
- Chest X-rays or CT scans: These identify lung changes and rule out other conditions.
- Pulse oximetry: This measures oxygen levels in the blood using a fingertip device.
- Arterial blood gas test: This assesses oxygen and carbon dioxide levels.
- Genetic testing: This is used for suspected Alpha-1 antitrypsin deficiency.
What are the main causes of COPD?
The leading cause of COPD is long-term smoking, but other factors also play a role. Prolonged exposure to secondhand smoke can harm nonsmokers, whereas air pollution, indoor cooking fumes and biomass fuel smoke increase risk in poorly ventilated areas.
Occupational hazards like dust and chemicals faced by miners, construction workers and factory workers further contribute. Genetics, particularly Alpha-1 antitrypsin deficiency, is another factor, although it is rare.
How can COPD be prevented?
COPD can be prevented mainly by reducing exposure to lung irritants. Quitting smoking is the most effective step. Avoiding exposure to secondhand smoke, harmful fumes and dust can also help reduce the risk. Vaccinations such as flu and pneumococcal shots help prevent infections that worsen COPD.
Maintaining good health through consistent exercise, nutritious eating and good hydration also supports lung health. Protective measures like wearing masks in high-risk environments can further reduce the chances of developing the disease.
Is COPD covered under health insurance?
COPD is typically covered under most health insurance policies. For instance, plans such as critical illness insurance often include coverage for COPD treatments, including hospitalisations, prescription medications and pulmonary rehabilitation programmes.
However, the extent of this coverage can vary depending on the specific plan, and insurers may impose waiting periods for pre-existing conditions before approving COPD-related claims. For this reason, it is essential to carefully review your policy wording to fully understand the scope of your coverage.
Conclusion
COPD can be challenging, but it is manageable with timely action. Recognising early warning signs, such as persistent cough or shortness of breath, is the first step toward effective care. Identifying these symptoms early enables prompt COPD treatment, which can slow disease progression. Alongside treatment, avoiding triggers like smoke and pollution and following medical guidance can ease the symptoms.
