Delhi Pollution: Lung Tests Needed?

As Delhi's pollution season looms, respiratory concerns intensify. Residents may face symptoms like coughing and breathlessness, prompting questions about lung health evaluations. While not mandatory for all healthy individuals, medical assessments, including spirometry, are recommended for those with persistent symptoms, pre-existing lung conditions, or increased exposure risks. Children, older adults, and those with heart or lung issues require extra caution.

Spirometry, a simple breathing test, helps diagnose conditions like asthma and COPD. However, a comprehensive medical history and physical examination guide further testing, which may include chest X-rays or other pulmonary function tests. The decision for testing should be symptom-driven, not fear-based.

Ignoring subtle symptoms like breathlessness or persistent cough can be detrimental, as some respiratory issues develop gradually. Pollution, particularly PM2.5, can aggravate existing conditions and trigger inflammation. While panic is unwarranted, increased attention to respiratory health is advised. Seeking medical advice for persistent or severe symptoms like breathlessness at rest or coughing up blood is crucial.

For symptom-free individuals, reducing exposure is key. This involves monitoring air quality, limiting outdoor exercise during high pollution, ensuring good indoor ventilation, and avoiding smoke. Masks and air purifiers offer supplementary protection but do not replace medical care or exposure reduction. Long-term respiratory health depends on various factors, including smoking, occupational exposure, and overall air quality.
