Diabetes and hearing loss are two of America’s most widespread health concerns. Nearly 30 million people in the U.S. have diabetes, and an estimated 34.5 million have some type of hearing loss. Those are large groups of people, and it appears there is a lot of overlap between the two.

A recent study found that hearing loss is twice as common in people with diabetes as it is in those who don’t have the disease. Also, of the 86 million adults in the U.S. who have prediabetes, the rate of hearing loss is 30 percent higher than in those with normal blood glucose.

Right now we don’t know how diabetes is related to hearing loss. It’s possible that the high blood glucose levels associated with diabetes cause damage to the small blood vessels in the inner ear, similar to the way in which diabetes can damage the eyes and the kidneys. But more research needs to be done to discover why people with diabetes have a higher rate of hearing loss. (ADA, 2016)
