The association between anemia and sensorineural hearing loss: A review.

Anemia affects a third of the world's population and contributes to increased morbidity and mortality, decreased work productivity, and impaired neurological development. In recent years, many studies have found a possible association between anemia and sensorineural hearing loss (SNHL), especially in various types of nutritional deficiency and hemoglobin disorders anemia. Anemia may affect hearing through various mechanisms, including affecting microcirculation in the ear, causing tissue hypoxia in the ear, and through inflammatory and oxidative stress pathways. This review aims to comprehensively analyze the association between various types of anemia and SNHL, including possible biological mechanisms, clinical features, and treatment strategies, and clarify the importance of anemia treatment and management in preventing SNHL.
