Diabetes mellitus and hearing loss
Clinical Otolaryngology and Allied Sciences
|April 1, 1995
Summary
Diabetic patients exhibit poorer hearing thresholds, particularly at lower frequencies. This hearing loss correlates with diabetes duration but not retinopathy stage.
Area of Science:
- Audiology
- Endocrinology
- Ophthalmology
Background:
- Diabetes mellitus is a systemic disease with various complications.
- Hearing impairment is a potential, yet understudied, complication of diabetes.
- Understanding the audiological impact of diabetes is crucial for patient care.
Purpose of the Study:
- To investigate hearing thresholds in diabetic patients.
- To compare diabetic hearing data with control populations.
- To explore correlations between diabetes duration, retinopathy, and hearing loss.
Main Methods:
- A prospective hearing survey was conducted on 102 diabetic patients.
- Hearing data were compared against three control population groups.
- Statistical analysis was performed to assess differences and correlations.
Main Results:
- Diabetic patients showed significantly worse average hearing thresholds than all control groups (P < 0.001).
- Hearing loss was most pronounced at low and mid frequencies.
- A positive correlation was observed between diabetes duration and hearing loss severity.
Conclusions:
- Diabetes is associated with significant hearing impairment, especially at lower frequencies.
- The duration of diabetes is a contributing factor to hearing loss.
- Diabetic retinopathy stage does not appear to influence the degree of hearing loss.
