Hearing Loss in Diabetes/ Hypertension Patients

Background: Hearing loss is increasingly recognized as a common but underdiagnosed complication in patients with diabetes mellitus and hypertension. Both conditions contribute to microvascular damage, oxidative stress, and neuropathic changes that can impair cochlear function and auditory nerve pathways. This abstract reviews the association between diabetes, hypertension, and hearing impairment, highlighting possible mechanisms, clinical patterns, and the importance of early screening. Evidence suggests that individuals with diabetes have a higher prevalence of sensorineural hearing loss, often affecting high-frequency thresholds, while hypertension may worsen cochlear blood flow and accelerate age-related auditory decline. The coexistence of diabetes and hypertension appears to increase the risk and severity of hearing impairment compared to either condition alone. Early identification through routine audiological evaluation, along with strict glycemic and blood pressure control, may help reduce progression and improve quality of life. Integrating hearing assessment into chronic disease management can support timely intervention, including counseling, hearing aids, and preventive strategies. Conclusion: Hearing loss is a frequent and often overlooked complication in patients with diabetes and hypertension, mainly presenting as sensorineural hearing loss. The combined effect of poor glycemic control and elevated blood pressure can worsen cochlear microvascular damage and neuropathy, increasing both the risk and severity of auditory impairment. Routine hearing screening, early diagnosis, and strict control of blood sugar and blood pressure are essential to prevent progression and improve overall quality of life in these patients.
