“…4,16 There have been several case studies linking sudden hearing loss to type 1 and type 2 diabetes both as the presenting symptom and as an isolated complication. [17][18][19][20][21][22] The results of several studies suggest that adults with diabetes have almost twice the risk of hearing loss compared with adults without diabetes, implying that hearing loss may be an underrecognized complication of diabetes. 1,23,24 In a recent cross-sectional investigation of more than 5000 NHANES participants who underwent audiometric testing from 1999 to 2004, participants with self-reported diabetes had significantly greater odds of having hearing loss across all frequencies and at all levels of severity (odds ratio [OR], 1.82 [95% confidence interval (CI), 1.27, 2.60] for low or mid-frequency; 2.16 [1.47, 3.18] for high frequency).…”
