Hearing health is often overlooked, yet its intricate connection with diabetes sheds light on the importance of holistic care. While diabetes primarily affects blood glucose levels, its impact extends beyond, potentially influencing hearing health.

Hearing loss makes it difficult to hear sound and speech. It can affect people’s self-esteem and confidence due to an impaired ability to communicate effectively. This can cause fewer opportunities in career or education, social isolation and emotional issues regarding lowered self-confidence. Hearing loss can range from mild to severe and can be either temporary or permanent.

Research

Recent studies have highlighted a correlation between diabetes and an increased risk of hearing impairment. The exact mechanisms behind this connection are complex and multifaceted. One contributing factor is believed to be the damage caused to blood vessels and nerves throughout the body, including those crucial for auditory function.

Blood glucose levels

Fluctuations in blood glucose levels, a hallmark of diabetes, may play a role in hearing health. High blood glucose levels can lead to reduced blood flow, impacting the delicate structures of the inner ear responsible for sound reception. Maintaining stable blood glucose levels through proper diabetes management is crucial for mitigating potential damage.

Neuropathy

Diabetes-related neuropathy, characterised by nerve damage, can extend to the auditory nerves. These nerves are essential for transmitting signals from the ear to the brain. Damage to these nerves can result in hearing difficulties. Regular monitoring and control of blood glucose levels are essential in preventing or slowing down this neuropathic impact on hearing health.

Inflammation

Inflammation, a common feature in diabetes, may affect the delicate structures within the inner ear. The cochlea, responsible for translating sound vibrations into electrical signals for the brain, can be vulnerable to inflammatory processes. This emphasises the importance of an anti-inflammatory lifestyle and dietary choices for people living with diabetes.

Maintaining optimal hearing health involves several key practices. Regular hearing check-ups, avoiding prolonged exposure to loud noises, and adopting a healthy lifestyle contribute to overall auditory wellbeing. These practices can also be particularly beneficial for those at risk of diabetes due to genetic factors or lifestyle choices.

What can you do?

• Continue to see your GP, credentialled diabetes educator, or dietitian to help with your ongoing management of diabetes
• Attend a hearing screen at least every three years, but sooner if you notice a difference in your hearing or your diabetes management
• Wear hearing protection if you are exposed to loud environments such as work or music festivals
• Limit the use of headphones with loud music and use headphones with volume limits

While the link between hearing health and diabetes is still being explored, acknowledging the potential impact of diabetes on auditory function is crucial. Proactive measures, including regular health check-ups, diabetes management, and a healthy lifestyle, can significantly contribute to preserving and protecting one’s hearing, ensuring a higher quality of life for years to come.
