Learn why regular checkups, early diagnosis & treatment matter
Aging and excessive noise exposure may account for a significant share of hearing loss. In some cases, however, hearing loss can result from an underlying medical issue. From infections and tumors to autoimmune disorders, various health conditions can affect how well you hear. Here’s a closer look to help you take action now.
Prevalence of Hearing Loss
Hearing loss affects people of all ages, including nearly 6% of Canadians 15 and older whose daily activities are impacted. Though more common later in life, hearing loss can develop at any stage. Many wait years before seeking help, whether due to stigma, lack of awareness or access, or other reasons, but early attention is critical for hearing and overall health.
The Way Hearing Works
Healthy hearing involves ears and the brain working together to locate and identify the direction, distance, and nature of sounds. Within the ear, tiny hairlike structures called “stereocilia” located atop hair cells detect sound vibrations. In turn, these vibrations are converted into electrical signals that travel to the brain for processing.
If any part of the auditory system is impacted — whether by a fluid buildup, structural damage, illness, or excess pressure — hearing can be compromised. Problems may affect sound clarity, balance, or ability to understand speech, especially in noisy settings.
Medical Causes of Hearing Loss
Most hearing loss falls into three main categories: conductive, sensorineural, or mixed. Conductive loss involves problems in the outer or middle ear, such as earwax buildup, fluid, or structural issues. Sensorineural loss affects the inner ear or hearing nerve and is often linked to aging, noise exposure, or inherited conditions. Mixed hearing loss combines elements of both.
Beyond aging and noise, several medical conditions can contribute to hearing loss, including:
- Ear infections
- Cerumen (earwax) buildup
- Head injury
- Tumors, such as acoustic neuromas
- Perforated eardrum
- Meningitis
- Ménière’s disease
- Diabetes
- Cardiovascular disease
- Ototoxic (poisonous to the ear) chemicals/medications
How Underlying Medical Issues Are Identified
Identifying a cause of hearing loss starts with a comprehensive hearing evaluation, including a physical exam, hearing tests, and a review of your symptoms and medical history. If anything unusual is detected, your audiologist may recommend follow-up with a physician, who can order tests to help determine the cause.
Treatment Options and Outlook
Treatment may vary based on the underlying cause. Infections may be addressed with medication, while conditions like Ménière’s disease often involve lifestyle modifications or specific therapies. For tumors or structural issues, surgery may be recommended. Permanent hearing is typically managed with properly fit hearing aids and audiologic support.
Often, the sooner a problem is identified — with the help of regular checkups — the better. In some cases, such as sudden hearing loss, hearing can potentially be restored with prompt treatment. Even when full recovery isn’t possible, early intervention can prevent further loss and unlock hearing solutions that improve communication, overall health, and quality of life.
