“Is it asthma, bronchitis or COPD?” A long cough, wheezing or breathlessness can raise all three questions. The right label matters because long-term treatment differs. Breathlessness can also come from pneumonia, heart disease, anaemia or other causes.
Seek urgent care if you cannot speak normally because of breathlessness, have blue lips, become drowsy or confused, or prescribed rescue treatment is not helping. Do not wait for a routine appointment.
How are asthma and COPD different?
| Question | Asthma | COPD |
|---|---|---|
| Typical pattern | Symptoms often vary over time, including at night or after triggers | Persistent breathlessness, cough or sputum, often progressing over time |
| Background | Can begin at any age; allergy may coexist | Often associated with tobacco, biomass smoke or occupational exposure |
| Testing | Looks for variable airflow limitation | Requires persistent obstruction on post-bronchodilator spirometry in the right clinical context |
| Treatment approach | Includes an inhaled corticosteroid-containing plan | Usually bronchodilator-centred; inhaled steroids are selected for particular patients |
These are useful patterns, not a self-diagnosis checklist. Some people have features of both. COPD is not restricted to cigarette smokers, and a symptom-free day does not exclude asthma.
What is spirometry?
Spirometry measures how much air you can blow out and how quickly. Testing before and after a bronchodilator can help assess airflow obstruction and response. It needs suitable technique and interpretation alongside your history.
For COPD, the diagnostic criterion is a post-bronchodilator FEV1/FVC ratio below 0.70, with compatible symptoms and exposure history. A chest X-ray or “smoker's cough” alone cannot diagnose it. Asthma may need repeat testing or other assessment when initial results are normal.
Why do doctors prescribe inhalers?
Inhalers deliver medicine to the airways. Needing regular treatment does not mean addiction. For asthma, an inhaled corticosteroid-containing treatment reduces airway inflammation and attack risk. Using only a short-acting reliever without this protection is not an appropriate long-term asthma strategy.
Some prescribed inhalers combine an anti-inflammatory medicine with a reliever. Not every combination inhaler can be used for sudden symptoms. Follow your own written plan; do not borrow an inhaler or switch medicines based on colour.
COPD treatment often uses long-acting bronchodilators. Inhaled steroids are useful for selected patients, especially when asthma coexists, rather than automatically for everyone.
Technique matters as much as the prescription
Bring your actual devices to the visit. The clinician can check how you prepare, inhale and hold your breath, and whether a spacer suits your device. Rinse and spit after a steroid-containing inhaler as advised to reduce mouth problems. Inhalers have possible side effects; the aim is the right medicine and technique at an effective dose.
A nebuliser is not automatically stronger or necessary for routine control. Ask for an action plan explaining daily treatment, worsening symptoms and when to seek emergency care.
Everyday steps that help
Avoid smoking and second-hand smoke; discuss cooking-fuel and work exposures. Stay active within your capacity, review appropriate vaccinations and identify personal triggers. Nasal allergy may need treatment too: see our dust allergy and rhinitis guide.

Common questions
Are inhalers addictive?
No. Symptoms returning after stopping can mean the condition remains active. Discuss any concern before changing treatment.
Does a normal X-ray exclude asthma?
No. Symptoms and appropriate breathing tests are more useful for this question.
Where can I get chest and asthma care in Patna?
At the allergy, asthma and respiratory clinic, bring inhalers, old prescriptions, breathing tests and details of attacks or hospital visits. Further assessment or specialist referral can be arranged when needed.
