Type 2 diabetes could increase the risk of loss of audition, they point out researchers who recommend hearing tests for patients with blood sugar disease.

"Many studies, although not all, have shown an association between diabetes and the deterioration of the ear in human subjects," said the Faculty of Public Health."The direct comparison of these studies is complex, due to the lack of consistency in the definition of auditory deterioration and other factors," he said in the association between diabetes and auditory deterioration tends to be more powerful in studies that included participantsyounger.It is possible that in older patients, other causes related to the age of auditory deterioration could mask the contribution of diabetes, he explained."This factor itself gives weight to the idea that type 2 diabetes can damage the ear," he explained.

Hearing loss affects more than 16 percent of American adults, and almost half of the people from 75 years of age have difficulty hearing, according to the National Sordic Institute.

Hearing loss has been linked to social isolation, depression, mental deterioration, dementia and a higher risk of falls, hospitalization and death, the researchers said.
