Background: More and more evidence suggest a connection between the most prevalent kind of anemia, which is caused by low iron levels, and hearing loss. Hearing loss was found to be twice as common in people with iron-deficiency anemia (IDA) as it was in those without the blood condition.
Objective: Review of the literature on effect of iron deficiency anemia on hearing.
Methods: We looked for data on Iron Deficiency Anemia and Hearing in medical journals and databases like PubMed, Google Scholar, and Science Direct. However, only the most recent or extensive study was taken into account between November 2011 and October 2022. References from related works were also evaluated by the writers. There are not enough resources to translate documents into languages other than English, hence those documents have been ignored. It was generally agreed that documents such as unpublished manuscripts, oral presentations, conference abstracts, and dissertations did not qualify as legitimate scientific study.
Conclusion: The prevalence of sensorineural hearing loss (SNHL) is higher in children with IDA. Screening for and treating IDA in children will enhance their health, regardless of whether or not it is associated with better hearing outcomes in those who are hard of hearing.
