Summary
Diabetics exhibit significantly higher rates of olfactory dysfunction (dysosmia) compared to non-diabetics. While olfactory function declines with age in both groups, specific diabetes-related factors did not show a clear link to smell impairment.
Area of Science:
- Otorhinolaryngology
- Endocrinology
- Neuroscience
Background:
- Diabetes mellitus is a complex metabolic disorder with potential systemic complications.
- Olfactory dysfunction (dysosmia) can be an indicator of neurological or systemic health issues.
- Previous research suggests a possible link between diabetes and altered smell perception.
Purpose of the Study:
- To investigate the prevalence of olfactory disturbances in diabetic patients.
- To compare olfactory function in diabetics versus a healthy non-diabetic control group.
- To explore potential correlations between olfactory ability and various diabetes-related parameters.
Main Methods:
- Olfacto-odorimetrical examinations were conducted on 110 diabetic patients.
- A control group of 110 rhinologically healthy non-diabetic individuals was included for comparison.
- Statistical analysis, including the chi-squared test, was employed to assess differences.
Main Results:
- A significantly higher percentage of diabetics (76.4%) experienced olfactory disturbances (dysosmia) compared to non-diabetics (41.8%).
- Both groups showed a statistically significant decrease in olfactory function with increasing age, indicated by a higher perceptual threshold.
- No clear connections were established between olfactory ability and factors such as sex, smoking habits, blood/urinary sugar levels, medication, metabolic condition, comorbidities, or diabetes duration.
Conclusions:
- Diabetic patients demonstrate a significantly higher prevalence of olfactory dysfunction compared to non-diabetics.
- Age-related decline in olfactory function is present in both diabetic and non-diabetic populations.
- Specific clinical and metabolic factors commonly associated with diabetes were not found to be significantly correlated with the observed olfactory impairment in this study.
