Ever heard of someone who is a non-smoker but is suffering from Chronic Obstructive Pulmonary Disease (COPD). Interesting, right? 

Chronic Obstructive Pulmonary Disease is a progressive lung condition that makes breathing more challenging than it ought to be. It is more commonly associated with smoking. However, it is not just smokers who are susceptible to the disease. Non-smokers can also develop the disease. There are multiple clinical research organizations in Michigan and Texas conducting COPD research exploring potential new therapies for both smokers and non-smokers. We must advance COPD research and care 

This blog will provide you with a comprehensive aspect of COPD in non-smokers, including its causes, symptoms, diagnosis and prevention 

What is Chronic Obstructive Pulmonary Disease (COPD)? 

Chronic Obstructive Pulmonary disease (COPD) is a progressive lung condition that is characterized by irreversible obstruction of the airways and alveolar destruction. These characteristics are more commonly referred to as conditions, namely Chronic Bronchitis and Emphysema. 

Chronic Bronchitis: 

Chronic Bronchitis involves long-term inflammation of the airways that carry air in and out of the lungs. 


Emphysema develops when the air sacs in the lungs undergo gradual damage. This leads to trapping of air and loss of elasticity, making it difficult to exhale. 

Factors contributing to the risk of Chronic Obstructive Pulmonary Disease in individuals who do not smoke.

Chronic Obstructive Pulmonary Disease (COPD) is normally caused by tobacco smoke. Even the researches that were conducted in the past primarily focused on smoking as the significant factor. However, in the last decade, a number of researches have indicated that there are factors beyond smoking that are linked to the development of COPD.  

Factors that contribute to the development of COPD in Non-smokers

  • Outdoor Air Pollution: Non-smokers can develop COPD from inhaling pollutants and dust particles in the air. Breathing in a mix of smoke and car exhaust can harm your lungs and consequently makes you prone to getting COPD. 
  • Indoor Air Pollution: In households across the globe, about 50% of all homes and 90% of rural homes rely on biomass fuels such as wood, charcoal, plant material, and animal dung, along with coal, for their primary source of domestic energy. Hence billions of people worldwide are exposed to the smoke produced by these biomass fuels. This indicates that exposure to smoke from biomass fuel could be considered one of the most significant global risk factors for the development of COPD. 
  • Workplace Exposure: Exposure to various chemicals in the workplaces such as manufacturing plants, construction sites and chemical factories poses significant risk to non-smoking individuals for COPD. 
  • Genetics: Genetics can play an important role in the development of COPD. A protein named alpha 1 anti-trypsin normally protects the lungs. Deficiency of this protein can cause the lungs to be damaged more easily, leading to an increased risk of developing COPD.  
  • Secondhand Smoke: Inhaling Secondhand smoke, which is the smoke produced by people who actively smoke can also contribute to the risk of developing COPD in non-smokers. 
  • Other Respiratory Conditions: Individuals dealing with chronic asthma may face an increased risk of developing Chronic Obstructive Pulmonary Disease. People who have suffered from tuberculosis are more susceptible to developing COPD due to long term impact of tuberculosis on lungs. 

Are Symptoms for Chronic Obstructive Pulmonary Disease in Non-smokers the same as Smokers? 

The symptoms of COPD in non-smokers are similar to those of smokers. It is important to note that people who have never smoked may experience fewer symptoms and their severity may vary compared to those of smokers. 

  •  Breathlessness: Challenges in breathing, particularly noticeable during physical exertion.
  • Wheezing: High pitched whistling sound produced during breathing. 
  • Chest Tightness: Feeling pressure or discomfort in your chest during breathing. 
  • Persistent Cough: A long-lasting cough accompanied by the production of mucus.
  • Fatigue: Lack of energy due to the increased effort required to breathe. 
  • Frequent Respiratory Infections: Recurrent occurrence of pneumonia and bronchitis. 

Diagnosis of COPD in Non-Smokers 

COPD is a disease that worsens over time. It is mostly diagnosed when the condition gets severe. The diagnostic processes for COPD in non-smokers include: 

  • Medical History: A detailed medical history in understanding the individual’s respiratory symptoms and any relevant history of respiratory conditions. 
  • Physical Examination: A thorough physical examination to check breathing patterns, and respiratory distress. 
  • Chest Imaging Studies: These include X-Rays and CT scans to assess lung structure. 
  • Blood Tests: They are performed to assess the oxygen levels and check for alpha-1 antitrypsin deficiency. 
  • Spirometry: It is often termed as pulmonary function test. It is used to measure the amount and speed of air that can be inhaled and exhaled from the lungs. 

Treatment of COPD in Non-Smokers 

  • Bronchodilators: To help open airways making it easier to breathe. 
  • Anti-inflammatory Drugs: Examples include corticosteroids, employed to diminish inflammation.
  • Pulmonary Rehabilitation: A comprehensive program to provide counselling and training to people to improve lung function. 
  • Oxygen Therapy: To provide supplemental oxygen when blood oxygen levels are inadequate. 
  • Antibiotics: To prevent lung Infection. 

Management of COPD in Non-Smokers 

Although chronic obstructive pulmonary disease comes with its own unique challenges and factors, it is crucial to understand that it can be managed with proper care. 

  • Avoiding secondhand smoke 
  • Avoiding air pollution 
  • Incorporating regular physical activities 
  • Yearly vaccinations to prevent respiratory infections 
  • Regular monitoring of lung function and symptoms  
  • Join support groups  
  • Maintaining a balanced diet  


COPD is not only a disease of smokers but can affect non-smokers as well. Awareness of the risk factors and symptoms of COPD in non-smokers is vital, as is early diagnosis and treatment. Diagnosing COPD in non-smokers involves a comprehensive evaluation, including medical history, physical examination, lung function tests, and imaging tests. Prevention of COPD in non-smokers entails avoiding secondhand smoke and reducing exposure to air pollution and chemicals. It is important to prioritize lung health and consult with healthcare professionals near you for accurate diagnosis and guidance in COPD management.
