Abstract
The precise patho‐physiology underpinning hearing loss in the context of diabetes remains incompletely elucidated. Typically, a gradual onset of bilateral sensorineural hearing loss, particularly at higher frequencies, is noted in individuals with diabetes mellitus. The primary objective of our study was to discern the prevalence of SNHL in diabetes mellitus and its potential correlation with glycated hemoglobin (HbA1c) levels. The study encompassed a cohort of 345 subjects, comprising 173 well‐matched healthy individuals serving as controls and 172 patients diagnosed with type 2 diabetes aged between 10 and 50 years. For the investigation, fasting blood sugar levels and HbA1c concentrations were measured in all subjects. Subsequently, pure tone audiometry (PTA) was conducted to assess hearing thresholds. The data analysis involved scrutinizing the degree, type, and association of hearing loss with HbA1c levels. The findings revealed that 28% of diabetic patients experienced SNHL, while 72% exhibited a normal hearing threshold. Within the diabetic group, out of 42 patients, 23 had mild, 9 had moderate, 9 had moderately severe, and 1 had severe degrees of hearing loss. Notably, the occurrence of hearing loss was more prominent at higher frequencies. Although an association between hearing loss and HbA1c was observed the highest correlation was identified in the 10‐13.9% HbA1c range. However, it is imperative to note that this correlation did not attain statistical significance in our study. Despite the absence of a significant correlation with HbA1c, our findings support a robust association between type 2 diabetes mellitus and hearing loss. This underscores the importance of further exploration into the intricate interplay between metabolic disorders and auditory function.
