Prevalence of Hearing Loss in Adults with Diabetes Mellitus Using Brainstem Evoked Response Audiometry: A Cross-Sectional Study

This study investigates the prevalence and characteristics of hearing loss among adults with diabetes mellitus (DM) using Brainstem Evoked Response Audiometry (BERA). Diabetes, a chronic metabolic disorder, has been linked to a variety of complications, including sensorineural hearing loss (SNHL), attributed to microvascular damage, oxidative stress, and neuropathy. Among 206 diabetic patients analyzed, 70% exhibited varying degrees of hearing loss, with mild SNHL being the most prevalent. Poor glycemic control (HbA1c > 8%) and a diabetes duration exceeding 10 years significantly increased the likelihood and severity of hearing impairment. The study highlights the role of diabetes-related complications, such as neuropathy and nephropathy, in exacerbating auditory dysfunction. These findings underscore the importance of early screening, glycemic control, and comprehensive management strategies to mitigate the impact of diabetes on auditory health and improve patients' quality of life.
