A chronic inflammatory lung disease causing obstructed airflow from the lungs, including emphysema and chronic bronchitis, primarily caused by smoking.
See a doctor if you have persistent cough or shortness of breath, especially if you smoke or have occupational exposures. Seek emergency care if you cannot catch your breath, lips or fingernails turn blue, rapid heartbeat, or if you're confused or drowsy—these indicate severe COPD exacerbation.
Find a Specialist NowChronic Obstructive Pulmonary Disease (COPD) is a serious lung condition that makes breathing progressively more difficult over time. In the Philippines, with high smoking rates and significant air pollution, COPD represents a major health burden. The good news is that COPD is largely preventable and, when diagnosed, its progression can be slowed with proper management.
COPD is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. It is an umbrella term that includes two main conditions:
Chronic Bronchitis: Long-term inflammation of the bronchial tubes (airways), causing chronic cough and mucus production. The airways are narrowed and inflamed, making it harder to breathe.
Emphysema: Damage to the alveoli (tiny air sacs) in the lungs where oxygen enters the blood. The walls of the air sacs are destroyed, reducing the surface area available for gas exchange.
Most people with COPD have features of both conditions in varying degrees.
In healthy lungs, air flows easily through the airways to the alveoli, where oxygen enters the blood and carbon dioxide is removed. In COPD:
Several factors make COPD a significant health issue in the Philippines:
Smoking: With approximately 16 million smokers, the Philippines has one of the highest smoking rates in Asia. Smoking is responsible for 80-90% of COPD cases.
Secondhand Smoke: Many Filipinos are exposed to tobacco smoke at home and in public places, despite smoking bans.
Indoor Air Pollution: In rural areas, cooking with wood, charcoal, or other biomass fuels in poorly ventilated homes significantly increases COPD risk.
Outdoor Air Pollution: Vehicle emissions and industrial pollution, particularly in Metro Manila and other urban centers, contribute to lung damage.
Occupational Exposure: Workers in construction, mining, manufacturing, and agriculture face dust and chemical exposures that increase COPD risk.
TB History: The Philippines has high TB rates, and TB can cause lung damage that increases COPD risk.
COPD develops slowly, often over decades. Early symptoms are easily dismissed:
Early Symptoms:
Progressive Symptoms:
Advanced Symptoms:
Exacerbations (flare-ups) are periods when symptoms suddenly worsen. They can be triggered by:
Exacerbations can be serious and require immediate medical attention. They accelerate lung function decline and increase mortality risk.
If COPD is suspected, your doctor will:
Spirometry: The key diagnostic test. You blow into a device that measures how much air you can exhale and how fast. Results showing FEV1/FVC ratio below 0.70 indicate airway obstruction.
Additional Tests:
GOLD Classification: COPD severity is classified based on spirometry results and symptoms:
While COPD cannot be cured, treatment can slow progression, relieve symptoms, and improve quality of life.
1. Smoking Cessation
The single most important intervention for COPD. Quitting smoking:
Resources include counseling, support groups, nicotine replacement therapy, and prescription medications.
2. Medications
Bronchodilators (open airways):
Inhaled Corticosteroids (ICS): Reduce inflammation; often combined with bronchodilators.
Combination Inhalers: Contain multiple medications for convenience.
Phosphodiesterase-4 Inhibitors: For patients with severe bronchitis and frequent exacerbations.
Antibiotics: During bacterial exacerbations.
3. Pulmonary Rehabilitation
A comprehensive program including:
Studies show pulmonary rehabilitation reduces breathlessness, improves exercise capacity, and decreases hospitalizations.
4. Oxygen Therapy
For patients with advanced COPD and low blood oxygen levels. Long-term oxygen therapy (LTOT) can extend survival and improve quality of life.
5. Vaccinations
Vaccines reduce the risk of respiratory infections that trigger exacerbations.
6. Surgery (Selected Patients)

Call for emergency help if:
COPD is largely preventable:
A COPD diagnosis is serious but not hopeless. With proper treatment, lifestyle modifications, and regular medical care, many people with COPD continue to lead active, fulfilling lives. The key is early diagnosis, quitting smoking (if applicable), and consistent management.
If you're a smoker, today is the best day to quit. If you have COPD, work closely with your healthcare team to optimize your treatment. Every positive step you take matters.
