You climb one flight of stairs and stop at the top to catch your breath. You tell yourself it is age, a little extra weight, or lack of exercise. But for millions of Indians, this everyday breathlessness is the first sign of COPD, a lung disease that most people live with for years without knowing its name.
Venkat (name changed), 54, an auto-parts dealer from Miyapur, had smoked for nearly 25 years. For the past three years he had a “smoker’s cough” every morning, and he had slowly stopped taking the stairs at his shop. Every winter he got a chest infection that took weeks to clear. “I thought it was just part of getting older,” he said.
A 15-minute breathing test (spirometry) showed his lungs were working at about 55% of what they should. He was diagnosed with moderate COPD. With the right daily inhalers, a pulmonary rehabilitation programme and, most importantly, quitting smoking, he now walks 4 km every evening and climbs to his first-floor shop without stopping.
World COPD Day falls on November 18, 2026. It is the perfect time to understand this disease, because the earlier it is found, the more lung function you can protect.
Key takeaways
- COPD is a long-term lung disease that narrows the airways and makes breathing out difficult.
- Breathlessness on exertion, a daily cough and frequent winter chest infections are early signs.
- Smoking is the leading cause, but in India cooking smoke, pollution and old TB are also major causes.
- A simple spirometry test confirms COPD; anyone over 40 with risk factors should get one.
- COPD cannot be fully reversed, but treatment can control symptoms and slow it down dramatically.
What COPD does to your lungs
COPD stands for Chronic Obstructive Pulmonary Disease. It is an umbrella term that includes two conditions which often occur together:
- Chronic bronchitis: the airways become swollen and produce excess mucus, causing a long-lasting cough with phlegm.
- Emphysema: the walls of the tiny air sacs are damaged and lose their elasticity, like old balloons that no longer spring back.
The result is that air gets trapped in the lungs. You can breathe in, but breathing out fully becomes harder. Over time, the lungs stay over-inflated, leaving less room for fresh air, which is why even small efforts like climbing stairs or bathing can leave you breathless.
Early signs most people ignore
COPD develops slowly over years. People unknowingly adjust their lives around it, walking slower, avoiding stairs, until the disease is already advanced.
The quiet clue: if you have started avoiding activities you used to do easily, like stairs, long walks or playing with grandchildren, because of breathlessness, that is a sign worth checking, not just “age”.
What causes COPD in India
- Smoking: cigarettes, beedis, hookah and chillum are the leading cause worldwide.
- Indoor smoke from cooking fuels: years of cooking with firewood, dung cakes, coal or kerosene. This is why many Indian women who have never smoked develop COPD.
- Outdoor air pollution: long-term exposure to vehicle smoke and dust in cities.
- Occupational exposure: dust, fumes and chemicals in construction, mining, textiles and factories.
- Second-hand smoke: living or working with smokers.
- Past lung damage: old tuberculosis or repeated childhood chest infections.
- Genetics: rarely, a condition called alpha-1 antitrypsin deficiency causes early COPD.
COPD or asthma? Key differences
| Asthma | COPD | |
|---|---|---|
| Usual age of onset | Often childhood or young adulthood | Usually after 40 |
| Main cause | Allergies, genetic tendency | Smoking, smoke and pollution exposure |
| Symptom pattern | Comes and goes, symptom-free between attacks | Persistent and slowly worsening |
| Airway narrowing | Largely reversible with treatment | Only partly reversible |
| Typical clue | Triggered by dust, pollen, cold air | Daily cough, phlegm and breathlessness on effort |
Some people have features of both, called asthma-COPD overlap. A pulmonologist can tell them apart with spirometry and your history, which matters because the treatment differs.
Spirometry: the 15-minute test that confirms it
Spirometry is a simple, painless breathing test. You take a deep breath and blow out as hard and fast as you can into a mouthpiece. The machine measures how much air your lungs hold and how quickly you can blow it out. It is repeated after an inhaler to see how much the airways open up.
Who should get tested? Anyone over 40 who smokes or used to smoke, has cooked with smoky fuels for years, has worked in dusty jobs, or has breathlessness, chronic cough or frequent chest infections. Your doctor may also suggest a chest X-ray or CT scan, oxygen level check and blood tests.
Stages of COPD
| Stage | Lung function (FEV1) | What it feels like |
|---|---|---|
| Mild | 80% or more of normal | Little breathlessness; maybe a morning cough. Often not noticed. |
| Moderate | 50–79% | Breathless on stairs or brisk walking. This is when most people first see a doctor. |
| Severe | 30–49% | Breathless with daily activities, frequent flare-ups. |
| Very severe | Below 30% | Breathless at rest; may need oxygen at home. |
How COPD is treated today
There is no cure that reverses the damage, but modern treatment works very well to control symptoms, prevent flare-ups and keep you active.
- Quitting smoking: the single most effective step at any age or stage. Nicotine replacement and counselling help a lot.
- Inhalers: long-acting bronchodilators that keep airways open, sometimes combined with steroid inhalers. Correct technique is essential.
- Pulmonary rehabilitation: a supervised programme of breathing exercises, walking training and education that improves stamina and confidence.
- Vaccines: yearly flu and pneumococcal vaccines to prevent infections that trigger flare-ups.
- Oxygen therapy: for people with low oxygen levels in advanced disease.
- Advanced options: for selected severe emphysema patients, interventional procedures such as bronchoscopic lung volume reduction may be considered.
8 habits for living well with COPD
Recognising a flare-up
A flare-up (exacerbation) is when symptoms suddenly get worse, often triggered by an infection or pollution. Early treatment can prevent a hospital stay. Watch for more breathlessness than usual, a change in phlegm colour or amount, more cough, fever, or needing your reliever inhaler much more often.
COPD myths, busted
Seek urgent care if
- You are breathless at rest or cannot speak in full sentences
- Your lips or fingertips look bluish
- You feel confused, very drowsy or unusually agitated
- Your reliever inhaler is giving little or no relief
- You have chest pain or a high fever with worsening breathing
