Common Causes of Chronic Cough and When to See a Chest Physician

A cough that lasts more than three weeks should never be ignored. Chronic cough can be a sign of underlying respiratory conditions such as asthma, chronic bronchitis, post-nasal drip, acid reflux, or lung infections. In many cases, environmental factors like pollution, smoking, or allergies can also contribute to persistent coughing. If your cough is accompanied by breathlessness, chest pain, blood in sputum, or unexplained weight loss, it is important to consult a chest physician immediately. Early diagnosis helps in identifying the root cause and prevents complications. Timely treatment can significantly improve quality of life and reduce long-term lung damage.
