In medicine we talk about the upper and lower airway, but in fact these two tracts are continuous with each other, lined with the same epithelium and affected by the same disease processes. In this podcast, Dr Toni Hazell and Professor David Price discuss how this knowledge affects the management of asthma and allergic rhinitis. Patients with asthma are more likely to have allergic rhinitis than the general population, and vice versa. By proactively asking about symptoms of allergic rhinitis in those with asthma, and vice versa, we can personalise our care and help patients to gain better control of both conditions.
