Kidney health and hearing might not seem related, but research shows they can affect each other more than we think. Both kidneys and hearing rely on good blood flow, and problems with one can impact the other. Here’s how they’re connected and what you can do to protect both.
How Kidney Disease Affects Hearing
- Toxins and Blood Flow
When your kidneys don’t work properly, they can’t filter toxins out of your blood. These toxins can affect blood flow, including to your ears. Without enough blood, the tiny parts inside the ear that help you hear can get damaged, leading to hearing loss. - Dialysis and Hearing
People who get dialysis for kidney failure are at a higher risk of hearing loss. Dialysis affects blood pressure and fluid levels, which can have a negative impact on hearing over time. - High Blood Pressure
High blood pressure is a major cause of both kidney problems and hearing loss. When your blood pressure is too high, it can damage the blood vessels that supply both your kidneys and ears, making both more vulnerable.
What Research Shows
Studies have found that people with kidney disease, especially those on dialysis, are more likely to have hearing loss. The longer kidney problems last, the more likely hearing issues become.
A study by the Hearing Health Foundation reviewed the medical records of 2,564 individuals aged 50 and older, including 513 with moderate chronic kidney disease. The results showed that 54.4% of those with chronic kidney disease experienced some level of hearing loss, compared to just 28.3% of individuals without kidney issues.
How to Protect Your Kidney and Hearing Health
- Control Blood Pressure
Since high blood pressure can damage both your kidneys and hearing, it’s important to keep it under control with a healthy diet, exercise, and medication if needed. - Check Kidney Function Regularly
If you’re at risk for kidney disease (e.g., diabetes or family history), have regular tests to monitor your kidney health. This can help catch any problems early. - Protect Your Ears
Avoid loud noises and use ear protection when necessary. Regular hearing checks can help spot hearing loss early, so it can be managed. - Live Kidney-Friendly
Eat a balanced diet, drink enough water, and limit processed foods to keep your kidneys healthy.
Kidney disease and hearing loss are connected in surprising ways. If you have kidney problems, especially if you’re on dialysis, your hearing could be affected too. By keeping an eye on both your kidney and hearing health, you can reduce your risk and take steps to protect both.
