Abstract : Diabetes mellitus (DM) being a chronic disease is associated with a wide range of both microvascular and macro vascular complications. Hearing loss is one such complication which is often over looked despite its impact on quality of life. Hence this study aimed to estimate the prevalence of sensorineural hearing loss (SNHL) and to determine the factors influencing its occurrence in patients with Type 2 Diabetes mellitus attending a tertiary hospital, Hyderabad. A hospital based cross-sectional study conducted over a period of one year from January 2024 to December 2024 in a tertiary care hospital, Hyderabad. A total of 180 patients with type 2 Diabetes mellitus attending the hospital were included in this study after excluding those with congenital hearing loss, non-diabetic and with SNHL due to other non-diabetic causes. A semi-structured questionnaire is used for taking detailed history, then ear, nose and throat examination followed by pure tone audiometry and measurement of glycosylated hemoglobin (HbA1c) levels. Data was collected and entered in MS Excel and analyzed by using SPSS software version 22. Out of 180 patients, 60% of them are males and 40% are females. The prevalence of SNHL among 180 patients was found to be 68.9%. Increasing age and, longer duration of diabetes and poor glycemic control had significant association with severity of SNHL with p value <0.05. This study showed 68.9% prevalence of SNHL among patients with type 2 diabetes mellitus. This study findings highlighted the need for routine auditory screening, especially in elderly diabetic patients and those with poor glycemic control.
