Background: Hearing, or auditory perception, refers to the capacity to detect vibrations and variations in the pressure of the surrounding medium over time using an organ like the ear. Hearing loss, commonly referred to as hearing impairment, is the condition of having a reduced or complete inability to perceive sound. Hearing loss refers to any level of impairment in the capacity to understand or perceive sound. Systemic diseases, such as systemic hypertension, diabetes mellitus, and dyslipidemias, have a direct or indirect role in the evaluation of individuals with sensorineural hearing loss. Aim and objectives: To determine the prevalence of sensorineural hearing loss in patients with diabetes and hypertension. Materials and Methods: The research is a randomised controlled trial that included a total of 160 patients, divided into four groups: 40 subjects diagnosed with diabetes, 40 subjects diagnosed with hypertension, 40 subjects diagnosed with both hypertension and diabetes, and 40 normal subjects without hypertension and diabetes. The study includes individuals aged 20–60 who have been diagnosed with diabetes and hypertension, as well as those without hypertension and diabetes. Results: Patients with diabetes mellitus had an average hearing loss of 35.6 dB, those with hypertension had 38.2 dB, and those with both conditions had 40.5 dB, while normal subjects had significantly lower hearing loss at 15.4 dB. The higher dB values indicate greater hearing impairment in patients with diabetes, hypertension, and both conditions compared to the normal group. The P value is statistically significant (P<0.05). Participants with diabetes mellitus, hypertension, and both conditions (diabetes and hypertension) were older on average compared to the normal group, with mean ages of 45.3 years, 47.0 years, 50.5 years, and 42.8 years, respectively. The P value is statistically significant (P<0.05). The duration of diabetes or hypertension was longest among participants with both conditions (12.8 years), followed by those with hypertension alone (10.1 years) and diabetes alone (8.4 years). The P value is statistically significant (P<0.05). Diabetic patients had an average HbA1c level of 8.2%, indicating suboptimal control. Hypertensive patients showed controlled blood pressure levels (130/85 mmHg), while those with both conditions had uncontrolled blood pressure (145/92 mmHg). Normal subjects were not assessed for these parameters. Patients with diabetes mellitus had SNHL in 25% of cases, hypertensive patients had it in 20% of cases, and those with both conditions had the highest prevalence at 45%. In contrast, only 5% of normal subjects had SNHL. Overall, SNHL was observed in 38 out of 160 participants, representing 100% prevalence among the study groups. Ototoxic effects were reported in 2.5% of participants (4 out of 160), head trauma in 1.25% (2 out of 160), viral infections in 0.63% (1 out of 160), and no cases of autoimmune inner ear disease were reported. Conclusion: The significance of preventive measures that can mitigate the factors that cause deterioration of hearing aids due to circulatory issues, particularly hypertension and hyperglycemia, and the necessity for a greater understanding of how these coexisting conditions impact hearing are emphasised.
