Chronic Obstructive Pulmonary Disease (COPD) is a chronic, progressive lung condition that was previously long assumed to be a direct consequence of cigarette smoking. But a growing body of scientific evidence educates us about a shocking and far from widely acknowledged reality: women are greater than men at risk of contracting COPD even if they do not smoke. It has numerous public health policy, biomedical research, and gender-specific health practice implications.
In this piece, we’re discussing why gender disparity exists, the biological and environmental factors, and what must be done in a way to protect against vulnerable groups largely women.
What is COPD?
COPD is a syndrome of diseases that brings about airflow limitation and breathing issues. The two most common ailments within the disease COPD are:
Chronic bronchitis – inflammation of the mucous membrane lining of bronchial tubes
- Emphysema – destruction of the alveoli (air sacs) in the lungs
Symptoms often include:
- Repeated coughing
- Wheezing
- Chest tightness
- Shortness of breath
- Weakness and long-term respiratory infections
While still the most recognizable risk factor, 25-30% of those with COPD have never smoked at all, and once more, most are women. This leads us to ask: what else is putting them at higher risk?
The Forging Gender Gap: What the Research Reveals
Subsequent studies show an alarming pattern: women are more likely than men to be diagnosed with COPD after controlling for smoking history.
A 2023 BMJ Open Respiratory Research paper found that if smoking and other lifestyle factors were controlled for, women were 47% more likely to have COPD than men. More disturbingly still, it was discovered that non-smoking women were 62% more likely than non-smoking men to have COPD.
This fact is not an isolated phenomenon. Several other researches, including those conducted by the American Lung Association, National Institutes of Health (NIH), and World Health Organization (WHO), have all replicated results of the same nature.
Why Women Are More Susceptible
1. Anatomical Reasons
Women’s lungs and airways are smaller compared to men’s. As a result:
- Poisons and contaminants travel deeper into the lungs
- There’s less reserve lung volume to compensate for injury
- Decline in airflow obstruction in spite of reduced exposure to irritants
3. Hormonal Factors
Estrogen is also involved in immune response and lung inflammation regulation. Estrogen is speculated by some scientists to potentially increase the impact of airborne toxins or the body’s reaction to lung injury and thus accelerate the initiation or exacerbation of COPD in women.
4. Occupational and Domestic Exposure
Women, especially in the developing and poorer countries, are most vulnerable to indoor air pollution because of:
- Cooking over biomass fuels (wood, cow dung, charcoal)
- Inadequate kitchen ventilation
- Household cleaning products
- Secondhand smoke from spouses and family members
Most frequently, this exposure will start early in life and continue over decades.
5. Secondhand Smoke
Even in industrial nations, the highest likelihood of exposure to passive smoking occurs indoors or in the workplace for women. Cumulative lung damage can result from passive exposure if it is combined with other risk factors like indoor air pollution.
6. Underdiagnosis and Misdiagnosis
COPD women are most typically misdiagnosed with asthma or anxiety, both because of gender bias and the fact that they present differently (more fatigue, anxiety, breathlessness). This missed diagnosis results in worse outcomes and faster disease progression.
Real-Life Consequences: How COPD Hurts Women Differently
In women, COPD is more likely to:
- Develop earlier in life (usually as early as in their 40s)
- Progress faster
- Be associated with more severe symptoms (dyspnea, fatigue)
- Result in higher hospitalization
Besides this, women with COPD have a poorer quality of life than men and have a higher prevalence of co-existing conditions such as depression, anxiety, and osteoporosis.
What Can Be Done?
1. Increased Awareness and Education
Health education programs can emphasize the fact that:
- COPD is not a smoker’s illness exclusively
- Women are particularly at risk
- Indoor air pollution kills like smoking
Education material should be culturally modified and made available to poor or rural women.
2. Improved Diagnosis and Screening
Doctors need to improve training to:
- Detect early signs of COPD in women,
- Use spirometry (lung function tests) more extensively,
- Avoid gender bias leading to incorrect diagnosis.
Early detection leads to better management and improved quality of life.
3. Cleaner Cooking Programs
Note: These are the guidelines as suggested by the WHO.
Initiatives like India’s Ujjwala Yojana, which provides cheap LPG connections to rural women, have already shown a beneficial impact on indoor pollution.
Governments must invest in such policies worldwide to reduce women’s exposure to harmful cooking fuels.
4. Targeted Medical Research
The overwhelming majority of medical research done so far has been male-based. There is a requirement to have:
- Specific research investigating how COPD develops in women
- Clinical trials with gender as a central variable
- Evaluation of risk factors for hormones
This research can guide gender-based treatment and prevention.
A Call to Action: The Health Sector Has a Responsibility to Respond
Health systems and providers must:
- Adopt a gender-sensitive approach in COPD treatment and prevention
- Detect non-smoking women as at-risk
- Seek access to affordable diagnoses and inhalers
- Act with NGOs and community organizations to sensitize
Women’s health needs to be discussed not just in maternal or reproductive medicine—but in chronic diseases like COPD that may not be apparent until it’s too late.
Conclusion
The reality of COPD being a “smoker’s disease” or a “man’s disease” needs to be erased forever. The truth is obvious: women are much more susceptible to COPD, even if they’ve never smoked.
This added risk is a synergistic product of biological, hormonal, environmental, and social factors. The sooner we acknowledge and act on this awareness, the quicker we can protect the lung health of tens of millions of women worldwide.
Let us not forget in our push towards science-based medicine and healthcare equity that air is a basic human right—and that right shouldn’t be harder for women to breathe.
