COPD (Chronic Obstructive Pulmonary Disease)
What is COPD?
Chronic Obstructive Pulmonary Disease (COPD) is a long-term lung condition that makes it hard to breathe. It happens when the airways and air sacs in the lungs become damaged or inflamed, causing the airways to narrow and lose their natural elasticity.
COPD usually develops slowly, over many years, and often includes two overlapping problems:
- Chronic bronchitis: long-term inflammation and narrowing of the airways, with a persistent cough and mucus
- Emphysema: damage to the air sacs (alveoli) in the lungs, which reduces the lungs’ ability to move oxygen into the blood
Common symptoms include breathlessness (especially on exertion), a chronic cough, wheezing, and repeated chest infections. COPD is a progressive disease and it doesn’t reverse, but with the right treatment, its progression can be slowed and symptoms significantly controlled, allowing patients to stay active.
Who is at Risk of COPD?
Smoking — including cigarettes, bidis, and hookah — is the leading risk factor for COPD in India, as it is worldwide.
But COPD in India looks different from the Western picture, where it is almost always tied to smoking. In India, a large proportion of patients — particularly women — develop COPD without ever having smoked. Key risk factors include:
- Biomass fuel smoke — cooking with wood, dung, or crop residue in poorly ventilated kitchens is one of the biggest COPD risk factors in India, and the main reason non-smoking women make up such a large share of Indian COPD patients
- Smoking — cigarettes, bidis, and hookah
- Occupational exposure: long-term exposure to dust, fumes, or chemicals at work
- Outdoor air pollution: particularly relevant in cities like Mumbai
- A past history of tuberculosis (TB): TB can leave lasting lung damage that increases COPD risk
- Increasing age: risk rises as lung function naturally declines with age
- Second-hand smoke exposure
- A rare genetic condition (Alpha-1 Antitrypsin deficiency) — uncommon, but worth testing for in early-onset or non-smoking COPD with no other clear cause
What are the Symptoms of COPD?
COPD symptoms usually develop gradually and are often mistaken for “normal aging” or dismissed as a smoker’s cough — which is a major reason COPD tends to be diagnosed late.
- Breathlessness: initially only during exertion (climbing stairs, walking briskly), progressing to breathlessness during routine activities or even at rest as the disease advances
- Chronic cough: often with mucus (phlegm), lasting weeks to months, frequently worse in the morning
- Wheezing: a whistling sound while breathing
- Chest tightness
- Frequent chest infections: colds that “go to the chest” more often than they used to, or take longer to clear
- Fatigue: reduced stamina for everyday tasks
- Unintentional weight loss and reduced muscle mass — more common in advanced disease
A key warning sign: if breathlessness or cough has been present for a while and you’ve simply adjusted your life around it — walking slower, avoiding stairs, skipping activities — rather than seeking treatment, that’s worth flagging to a doctor rather than accepting as normal.
How is COPD Diagnosed?
- Detailed history & Physical examination
- Spirometry is the essential test for confirming COPD.
- Chest X-ray or CT scan

Why Is It Necessary to Follow Up With a Pulmonologist Regularly?
COPD is a lifelong condition that changes over time and it isn’t a one-time diagnosis-and-prescribe situation.
- COPD is progressive but its course can be changed.
- Untreated COPD leads to exacerbations.
- COPD rarely travels alone. It’s strongly linked with heart disease, osteoporosis, muscle wasting, depression, and lung cancer risk; untreated COPD makes these harder to detect and manage.
- Quality of life is directly at stake. Breathlessness that goes untreated leads to inactivity, which leads to deconditioning, which leads to more breathlessness — a downward spiral that’s preventable with early, appropriate treatment.
- Misdiagnosis is common: COPD can be mistaken for asthma, TB, or simply “old age,” and the wrong treatment path delays real relief and can allow damage to continue silently.
Frequently Asked Questions (FAQs) – COPD
No. Both cause breathlessness and wheezing, but they are different conditions. Asthma usually starts in childhood, is often linked to allergies, and airway narrowing is largely reversible. COPD usually develops in adulthood, is linked to smoking or biomass smoke exposure, and airway narrowing is only partially reversible. Some patients have features of both, which your pulmonologist will assess with spirometry.
COPD cannot be cured or fully reversed, since the lung damage is permanent. However, with the right treatment, its progression can be significantly slowed, symptoms well controlled, and quality of life maintained for many years.
Not necessarily. Oxygen therapy is only needed in more advanced COPD, when blood oxygen levels are significantly low.
Quitting smoking (or stopping biomass smoke exposure) is the single most effective step you can take at any stage of COPD. It won’t reverse existing lung damage, but it significantly slows further decline in lung function and reduces exacerbations.
Yes, and it’s actively encouraged. Structured exercise through pulmonary rehabilitation improves stamina, breathlessness, and quality of life. Avoiding activity due to breathlessness often makes symptoms worse over time by causing deconditioning.
