Quick Answer<\/p>\n

A persistent cough is not always a chest infection. While bronchitis and pneumonia are common culprits, a cough lasting more than three weeks may also be caused by asthma, acid reflux, postnasal drip, tuberculosis, air pollution, or a blood pressure medication. In Pakistan, cough variant asthma and TB are among the most frequently missed diagnoses. A cough lasting eight weeks or more in an adult always warrants a proper medical evaluation.<\/p>\n<\/div>\n

Most people in Pakistan reach for a cough syrup and assume a stubborn cough will clear up on its own. Sometimes it does. But when a cough drags on past two or three weeks, especially without a fever or runny nose, the cause is often something other than a simple chest infection.<\/p>\n

Lahore winters are a good example of how complicated this gets. The city’s smog season runs from October through January, and during those months respiratory clinics fill with patients whose coughs have lasted for weeks. Some have a genuine chest infection. Many do not. A cross-sectional study at KRL Hospital Islamabad found that cough variant asthma was the leading cause of chronic cough in Pakistani adults, accounting for 47% of cases, while acid reflux, allergic rhinitis, and blood pressure medications made up much of the rest.<\/p>\n

Understanding what is actually driving a cough matters because the treatment for each cause is completely different. Antibiotics, for instance, do nothing for an asthma-related cough or an acid reflux cough, yet they are among the most overprescribed medicines in Pakistan for exactly this symptom.<\/p>\n
