Abstract

Allergic rhinitis (AR) and obstructive sleep apnea (OSA) are two common conditions that significantly affect the quality of life of affected individuals. Both conditions are independently associated with adverse health outcomes such as cardiovascular disease, cognitive dysfunction, and reduced productivity. However, the co-existence of AR and OSA may exacerbate the severity of both diseases, leading to a greater burden on public health. This review explores the pathophysiological mechanisms linking AR with OSA, including the role of inflammation, nasal obstruction, and the upper airway anatomy. Additionally, we examine current treatment strategies for managing both conditions, highlighting the importance of multidisciplinary approaches in optimizing patient outcomes.
