Breathing problems range from a lingering cough after a cold to asthma, COPD and pneumonia. Dr Sujith Chadala at Continental Hospitals, Gachibowli examines the chest, checks oxygen levels, orders an X-ray or lung function test where needed, and treats the cause — including correct inhaler technique, which many patients have never been shown.

Overview
A cough that lasts more than three weeks, wheezing at night or breathlessness on climbing stairs are reasons to be checked rather than to keep taking cough syrups. Common causes include post-viral cough, asthma, allergic rhinitis with post-nasal drip, acid reflux, COPD in smokers and, less often, tuberculosis.
Dr Chadala's training in critical care means early recognition of when a chest infection is becoming serious — low oxygen, rapid breathing or confusion — and when hospital care is needed.
For long-term conditions like asthma and COPD, the goal is fewer flare-ups and a normal active life, with inhalers chosen and taught to suit you.
What this covers
- Cough lasting more than three weeks
- Asthma and wheezing
- COPD and smoker's cough
- Pneumonia and bronchitis
- Allergy-related cough and sneezing
- Breathlessness on exertion — initial evaluation
- Recovery after COVID-19 or other viral chest infections
When should you see a doctor?
- Cough for more than three weeks or coughing up blood
- Wheezing, chest tightness or night-time cough
- Breathlessness that is new or getting worse
- Fever with cough and yellow or green phlegm
- Weight loss or night sweats with cough
How care works
- 1
Listen and measure
Chest examination and pulse oximetry, with peak flow or spirometry where useful.
- 2
Targeted imaging and tests
Chest X-ray, blood tests or sputum tests when the history suggests infection or another cause.
- 3
Treat and teach
Medicines and inhalers with a hands-on demonstration of the correct technique.
- 4
Prevent the next episode
Triggers, smoking cessation and vaccination (influenza, pneumococcal) are discussed where appropriate.
Emergency warning signs
Call 108 or go to the nearest emergency department immediately if you notice:
- Breathlessness at rest or inability to speak in full sentences
- Oxygen saturation below 92% on a home pulse oximeter
- Bluish lips, confusion or drowsiness
- Chest pain with breathlessness
Before your visit
- Your inhalers and spacer, if you use them
- Any earlier chest X-rays, CT scans or lung function reports
- Home oxygen saturation readings, if available
Frequently asked questions
When is a cough considered chronic?
In adults, a cough lasting more than eight weeks is chronic, and one lasting three to eight weeks is sub-acute. Any cough beyond three weeks deserves a medical review, and a chest X-ray is often advised.
Are inhalers addictive or harmful?
No. Inhalers deliver a small dose of medicine directly into the lungs, so they need much lower doses than tablets. For asthma and COPD, they are the safest and most effective treatment.
What oxygen level is normal?
A pulse oximeter reading of 95–100% is normal for most healthy adults at rest. Readings persistently below 92–94%, or a fall with breathlessness, need prompt medical attention.
