Diabetics at greater risk for hearing loss
People with diabetes are usually aware of their increased risk of kidney, cardiovascular, and visual disorders. However, most diabetics don’t know they are more than twice as likely to have hearing loss as those without the disease. And the risk is greater among younger diabetics than older.
Younger diabetics at greater risk
A recent study in Japan was published in Nov. 2012 in The Journal of Clinical Endocrinology & Metabolism. Led by Chika Horikawa, the team examined data from 13 previous studies published between 1977 and 2011. Their conclusion? Not only were diabetics 2.15 times as likely as others to have hearing loss, but those under age 60 had 2.61 times the risk while those over 60 had 1.58. In a related study by the National Institutes of Health, it was shown that more than 40% of people with diabetes had some degree of hearing loss.
Link between diabetes and hearing loss
The link between diabetes and hearing loss is not yet fully understood. Some think that high blood sugar levels may damage the blood vessels in the ears. Others caution that certain medications commonly used by diabetic patients, such as diuretics, may be a contributing factor. Though more research is needed in order to understand the connection between diabetes and hearing loss, according to Horikawa, “these results propose that diabetic patients are screened for hearing impairment from an earlier age compared with nondiabetics,” particularly because untreated hearing loss is associated with an increased risk of dementia and depression.
