[Chronic cough: recommendations for primary care physicians]

Chronic cough, defined as a cough lasting longer than 8 weeks, is a common complaint in primary care settings. It is now recognized as a distinct clinical entity, often associated with cough reflex hypersensitivity. Chronic cough has an impact on quality of life and assessing it remains a key component in tailoring management. The initial workup includes a chest X-ray, spirometry, and complete blood count. Current guidelines emphasize the importance of a thorough clinical assessment to identify and address modifiable causes and limit empirical treatments, as previously recommended. The etiological spectrum has expanded to include conditions such as obesity and sleep apnea, underlining the need for a multidisciplinary approach. In the absence of a clear etiology or treatment response, referral to a specialist is recommended.
