Many things can cause hearing loss. For instance, it can be caused by normal aging, disease, or even excessive noise. It is thought that chronic high blood glucose in diabetics may cause nerve damage in the inner ear, leading to the hearing impairment. Another possible reason could be the poor blood circulation to the inner ear. It's estimated that diabetics are twice as likely to experience hearing loss than someone without diabetes.
If you have diabetes, consider having your hearing checked every year or two. A hearing aid can be used before diabetes hearing loss impacts the quality of your life. Diabetics should strive to keep their blood glucose levels well-managed by following a diabetes treatment plan in order to avoid further health complications.
