A chronic cough lasting more than eight weeks can result from several underlying conditions. Common causes include asthma, postnasal drip, smoking, allergies, acid reflux, chronic bronchitis, and respiratory infections. Environmental pollutants and certain medications can also trigger persistent coughing. Identifying the root cause early is essential to prevent complications and improve breathing comfort. Medicover Hospitals provides detailed respiratory evaluations, including lung function tests and imaging, to determine the cause of chronic cough and offer targeted treatment for long-term relief.
