Iron deficiency anemia and hearing.
Iron deficiency anemia is a frequently occurring clinical disorder. Despite the suggested association with hearing loss in the literature, cochlear sequelae of iron deficiency have yielded conflicting results in experimental studies. Auditory function was tested in iron-deficient and normal male Wistar albino rats using distortion product otoacoustic emissions and auditory brainstem response audiometry for the clarification of the opposing results in the literature. Hemoglobin, hematocrit, serum iron and albumin levels were monitored to verify iron deficiency. Although dramatic differences in weight gain and blood test parameters were noted, no significant change in auditory function due to iron deficiency was detected.
