Bronchitis cases are climbing sharply across North India as winter sets in, with doctors warning that delayed testing could result in long-term lung damage. The drop in temperatures combined with severe pollution has led to a surge in respiratory illnesses, making early diagnosis critical for preventing complications such as chronic obstructive pulmonary disease (COPD).

Speaking to Mathrubhumi, Dr Tanish Mandal, Consultant Pathologist and Zonal Technical Chief, North India, Apollo Diagnostic Delhi, said early detection and proper treatment are essential to avert severe respiratory complications linked to bronchitis.

He emphasised that timely tests play a crucial role in saving the lungs and improving the overall quality of life.

Acute bronchitis often develops suddenly after a cold or infection, while chronic bronchitis can persist for months and cause lasting lung damage. Exposure to cold air, poor air quality, and viral infections are the most common triggers. 

The condition occurs when the bronchial tubes—air passages that carry air to and from the lungs—become inflamed, leading to persistent cough, wheezing, chest tightness, and mucus production. Some may also experience mild fever, sore throat, or body aches.

According to experts, timely testing is key to identifying bronchitis and preventing it from progressing into more severe respiratory conditions.

The following tests are recommended for individuals experiencing bronchitis symptoms:

• Physical examination: Doctors assess symptoms such as wheezing, crackles, or blocked airflow to form an initial diagnosis.

• X-ray: Anyone with a cough lasting more than two weeks or difficulty breathing should undergo a chest X-ray to check for lung inflammation.

• Lung function tests: These measure how effectively the lungs are working.

• Sputum test: Helps detect infections or allergens to confirm bronchitis and guide treatment.

• Spirometry: Determines how much air moves in and out of the lungs and identifies bronchitis.

• Blood tests: Used to detect infections or low oxygen levels and aid in determining severity.

Treatment typically includes rest, hydration, inhalers, cough medicines, and strict avoidance of pollutants and smoke. Preventive measures include wearing masks outdoors, using air purifiers at home, quitting smoking, and undergoing regular winter health check-ups.

With pollution and cold weather intensifying, doctors stress that a lingering winter cough should never be ignored, urging people to seek timely testing to protect their lungs.
