In this discussion, Professor Fan Chung, an expert in Respiratory Medicine from Imperial College London, delves into the often-overlooked issue of Upper Airway Cough Syndrome (UACS). He highlights that chronic cough may stem from UACS in many cases, emphasizing the importance of correct diagnosis and treatment. The conversation covers the efficacy of different antihistamines, the link between UACS and asthma, and the challenges in managing symptoms, especially in children. Chung advocates for a comprehensive treatment approach addressing both upper and lower airway concerns.
