Most people know that diabetes can damage the eyes, kidneys, nerves, and heart. But did you know it may also affect your hearing?

Emerging research shows a clear connection between high blood sugar and hearing loss. This complication is often overlooked, but identifying it early could protect more than just your ears.

👂 How Diabetes May Affect Hearing

Your inner ear relies on tiny blood vessels and nerves to detect and transmit sound. Just like high blood sugar can damage vessels in the eyes or kidneys, it may also impair circulation in the ear. Over time, this can lead to:

• Reduced blood flow and oxygen to hearing structures

• Nerve damage that affects how sound signals are processed

• Higher risk of inflammation in the auditory system

This kind of hearing loss often develops gradually and may not be recognized until it becomes more severe.

🚨 Signs to Watch For

If you have diabetes or insulin resistance, be alert to:

• Needing to turn up the TV or radio

• Struggling to hear in group conversations

• Frequently asking others to repeat themselves

• Ringing or buzzing in the ears (tinnitus)

• Feeling like sounds are muffled or distant

These may be early signs of inner ear nerve damage related to high blood sugar.

🔬 The Evidence

Several studies, including findings from the National Institutes of Health, suggest that adults with diabetes may be up to twice as likely to experience hearing loss compared to those without the condition.

Even in people with prediabetes, subtle declines in hearing have been observed, especially in higher frequency ranges. The higher the A1c, the greater the potential risk.

✅ What You Can Do

1. Prioritize blood sugar control
Keeping your A1c within target range helps protect blood vessels and nerves, including those in the ears.

2. Schedule hearing tests
Ask for a hearing screening, especially if you're over age 40 or noticing changes.

3. Use a CGM if possible
Continuous glucose monitoring can help you avoid spikes and dips that affect vascular health.

4. Respond early to symptoms
Hearing changes can be subtle at first, but early detection allows more options for support.

5. Talk to your care team
Hearing health deserves attention just like vision and kidney function. Don't overlook it!
