Diabetes and Hearing Loss

Get your hearing tested every year if you have diabetes.

Over time, blood sugar levels that are too high or too low can damage nerves that affect your hearing. Learn how you can help prevent hearing loss if you have diabetes.

Hearing loss happens for many reasons. You probably know that it can happen as you age or if you spend too much time around loud noises. You may not know that having diabetes puts you at risk for hearing loss. Managing your blood sugar is a critical part of your diabetes care. It can also help protect your hearing.

The Diabetes and Hearing Loss Connection

Diabetes can lead to nerve damage that affects many parts of the body, including your hands, feet, eyes, and kidneys. Diabetes can also cause nerve damage in your ears.

Over time, high blood sugar levels can damage small blood vessels and nerves in the inner ear. Low blood sugar over time can damage how the nerve signals travel from the inner ear to your brain. Both types of nerve damage can lead to hearing loss.

Hearing loss is twice as common in people who have diabetes as it is in people of the same age who don’t. Even people with prediabetes (blood sugar levels higher than normal but not high enough yet to have type 2 diabetes) have a 30% higher rate of hearing loss than people with normal blood sugar levels.

Signs of Hearing Loss

Hearing loss can happen slowly, so it can be hard to notice. Often, friends and family members will notice your hearing loss before you do.

Signs of hearing loss include:

• Often asking others to repeat themselves.
• Trouble following conversations with more than one person.
• Thinking that others are mumbling.
• Problems hearing in noisy places, such as busy restaurants.
• Trouble hearing the voices of small children and others with quiet voices.
• Turning up the TV or radio volume too loud for others who are nearby.

Problems with your inner ear may also affect your balance.

How To Protect Your Ears

You can’t reverse hearing loss, but you can follow these tips to help protect your ears:

• Keep your blood sugar as close to your target levels as possible.
• Get your hearing checked every year.
• Avoid other causes of hearing loss, including loud noises.
• Ask your doctor whether any medicines you’re taking can damage your hearing and what other options are available.

You should have your hearing tested by an audiologistexternal icon (a health care professional who evaluates your hearing for medical problems) when you first find out you have diabetes and then every year after. Make it part of your diabetes care schedule. If you think you have hearing loss, talk to your doctor. They can help you decide if you should see an audiologist.

Hearing loss can be frustrating for you and your family, and it can affect your social life. There are many reasons to keep your blood sugar in your target range—protecting your hearing is just one of them. Plus, you’ll feel better and have more energy while you do it!
