Listen to Story Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease that makes breathing difficult. It includes conditions like chronic bronchitis and emphysema, both of which lead to airflow obstruction and respiratory symptoms such as chronic cough, wheezing, and shortness of breath. COPD is a leading cause of death worldwide, affecting millions of people.
The primary risk factor for COPD is smoking while air pollution is an environmental risk factor. Approximately 80-90% of COPD cases are linked to tobacco use. Inhaling smoke damages the airways and alveoli (air sacs in the lungs), causing inflammation, narrowing of air passages, and loss of lung tissue.
In 2021, over 3.1 million people died of COPD, as per the World Health Organisation. It is the fourth leading cause of death worldwide.
Other risk factors include long-term exposure to air pollution, occupational dust, and chemicals, as well as a genetic condition known as alpha-1 antitrypsin deficiency, which can increase vulnerability to lung damage. COPD develops over many years, often without noticeable symptoms until the disease has advanced. Symptoms commonly include persistent cough, mucus production, fatigue, and frequent respiratory infections.
Over time, COPD can lead to severe difficulty in breathing and reduced quality of life. Managing COPD involves a combination of lifestyle changes, medications, and therapies. The first step is quitting smoking, which is the most effective way to slow the progression of the disease.
Medications like bronchodilators and inhaled steroids can help open the airways, reduce inflammation, and ease breathing. In more severe cases, oxygen therapy may be needed to ensure adequate oxygen levels in the blood. Pulmonary rehabilitation, which includes exercise and breathing techniques, is also recommended to improve lung function and overall well-being.
Though COPD cannot be cured, early diagnosis and proper management can help control symptoms and improve the quality of life. Regular check-ups and staying proactive with treatment are key to living well with COPD..
