Purpose of Review <p>The purpose of this paper is to provide an overview for chronic cough and specifically explore how allergies play a role in chronic cough.</p> Recent Findings <p>Recent literature focuses on the interplay between cough and allergic diseases, such as non-asthmatic eosinophilic bronchitis and allergic rhinitis. Additionally, newer studies explore the interplay between inflammation and cough sensitivity.</p> Summary <p>The etiology of chronic cough is often multifactorial and can be difficult to narrow down. Allergic diseases often present with a cough as a main symptom and therefore allergic diseases should be explored as part of a work-up for a chronic cough. Additionally, allergic responses and inflammation have been shown to sensitize cough receptors, which may make patients more susceptible to developing a hypersensitivity cough or neurogenic cough.</p>
