Asthma is one of the most common long-term lung conditions in India, affecting children and adults in cities and villages alike. Asthma prevalence has been rising along with air pollution, urbanisation and changing lifestyles, yet many people still do not know they have it. Understanding the numbers helps explain why early diagnosis matters so much.
Asthma Prevalence in India: The Numbers
According to Global Burden of Disease 2019 data, India accounts for about 12.9% of global asthma cases (around 34.3 million people) but a disproportionately high 42.3% of global asthma deaths. In other words, India has roughly one in eight asthma patients in the world, but a far larger share of deaths. doaj
A major reason is under-diagnosis and under-treatment. One analysis of Indian data suggests that only about a quarter of asthma cases receive a formal diagnosis, and few patients use inhaled corticosteroids. Many people live with wheezing and cough for years, treating it as a “habitual cough” or a recurring cold. globalasthmanetwork
Why Is Asthma Prevalence So High in India?
Asthma develops from a mix of genetic and environmental factors, and several of them are common in India. Dust, pollen, mould, cockroaches and pet dander trigger allergic asthma, while smoke from vehicles, factories, crop burning and tobacco irritates the airways. Indoor smoke from cooking fuels such as wood and dung cakes also matters; one Indian study estimated that about one-third of asthma cases could be avoided by reducing the use of solid fuels. A family history of asthma or allergies adds to the risk, and you can read more about this in our guide to the risk factors of asthma. repec
Asthma in Children and Adults
Asthma is among the most common chronic conditions in childhood, but it can begin at any age. Children are often affected by dust mites, viral infections, smoke and weather changes, and parents can learn more about asthma triggers in children. In adults, asthma may be linked to workplace dust, smoking, obesity and allergies, and living with it can affect sleep, work and mood, as explained in the psychological effects of asthma.
Seasons and Asthma
Asthma prevalence is not the only concern; flare-ups also change with the seasons. Cold, dry air and infections make symptoms worse in winter, which is why many patients ask why asthma is worse in winter. In summer, heat, dust storms and high pollen counts become the main triggers, and these tips to avoid asthma triggers during summer can help.
Recognising Asthma Early
The typical symptoms are wheezing, a tight chest, breathlessness and cough, often worse at night or early morning. Spotting the first sign of asthma can lead to quicker treatment. Some people have only a long-lasting dry cough without wheezing, which is called cough variant asthma and is often missed.
If you already have asthma, watch for the signs of asthma getting worse, such as needing your reliever inhaler more often or waking up at night with symptoms.
Is Asthma Curable and How Is It Treated?
Asthma cannot be cured completely, but it can be controlled very well. Our article on whether asthma is curable explains what to expect from long-term care. Treatment usually combines a quick-relief inhaler with a daily preventer inhaler for inflammation, and the details are covered in how asthma is treated. Regular use of preventer inhalers is one of the best ways to reduce attacks and hospital visits.
How to Reduce Your Risk
You cannot change your genes, but you can reduce exposure to triggers: stop smoking and avoid second-hand smoke, keep your home clean and dry, use cleaner cooking fuel and wear a mask on polluted days. For a full list, see how to avoid asthma.
Conclusion
The high asthma prevalence in India, combined with late diagnosis and poor treatment, is why so many deaths still occur from a condition that can be controlled. If you or your child has a persistent cough, wheezing or breathlessness, consult Dr. Pankaj Gulati at Breath Clinic, Jaipur, for tests and a proper treatment plan.

Frequently Asked Questions (FAQs)
1. How many people have asthma in India?
Estimates from the Global Burden of Disease 2019 study put the number at about 34 million, around 13% of asthma cases worldwide.
2. Why do so many asthma deaths happen in India?
Late diagnosis, under-use of preventer inhalers, air pollution, poor access to care and fear of inhalers are the main reasons.
3. What are the early warning signs of asthma?
Wheezing, coughing at night, chest tightness and breathlessness on exertion are early signs. See the early warning signs of asthma for more.
4. Is breathlessness always asthma?
No. Breathlessness can also come from COPD, heart problems, anaemia, anxiety or infections. Our article on the difference between asthma and breathlessness explains how to tell them apart.
5. What should I do during an asthma attack?
Sit upright, stay calm and use your reliever inhaler as prescribed. If there is no relief within a few minutes, or you cannot speak in full sentences, go to the hospital immediately. Learn more about an asthma attack.
