A local audiologist is doing his part to join the diabetes fight. Dr. Richard Navarro of the Active Hearing and Tinnitus Center is donating to Step Out for Diabetes.

The event is sponsored by the American Diabetes Association, and will take place Oct. 13 at Whataburger Field. Navarro will donate $5 for every hearing test he administers and $25 for every pair of hearing aids purchased in October and November.

"The combination of diabetes and high cholesterol damages the blood vessels in the inner ear," Navarro said. "When the inner ear is not able to get the nutrition that it needs, or to get rid of waste products, then the ear is basically poisoned over time."

Diabetics have increased risk for hearing loss and tinnitus, which is a ringing in the ear.
