What are the common causes of hearing loss?

Many of us experience hearing loss at some point in our lives. Whether it is a gradual, permanent decline that often occurs with age or a temporary issue caused by earwax buildup, an infection, or a cold, it is important to have your hearing checked to identify potential problems and reduce the risk of long-term complications.

Recognizing a possible long-term hearing problem early can help ensure that appropriate treatment and support are provided as soon as possible. Follow along as El Dorado Hearing explores some common causes of hearing loss.

Infection of the Ear Canal or Middle Ear

The ear canal carries sound from the outer ear to the eardrum, which separates the outer and middle ear. The Eustachian tube connects the middle ear to the back of the nose and throat and helps regulate pressure and drain fluid. Infections, inflammation, or fluid buildup in these areas can affect hearing.

Ear infections are common, particularly in children. Depending on the type and severity of the infection, treatment may include ear drops or oral medication. Antibiotics are used for certain bacterial infections, while other infections may require different treatments.

Fluid buildup in the middle ear can cause temporary hearing difficulties. Colds, flu, sinus infections, and allergies may contribute to inflammation or Eustachian tube dysfunction. Smoking and exposure to tobacco smoke can also increase the risk of certain ear problems. A healthcare professional can recommend appropriate treatment to relieve symptoms and address the underlying cause.

Hypertension

Hypertension is the medical term for high blood pressure. High blood pressure is associated with an increased risk of hearing problems, although the exact relationship is still being studied. Changes affecting blood vessels and circulation may contribute to damage involving the delicate structures of the inner ear.

Smoking, an unhealthy diet, and other lifestyle factors can contribute to high blood pressure. Managing these risk factors can benefit your overall health. Genetics can also play a role, so speak with your healthcare provider if you are concerned about your blood pressure or its potential effects on your hearing.

Diabetes

Research has found an association between diabetes and hearing loss. People with diabetes are more likely to experience hearing difficulties than people without the condition. The exact reasons are still being investigated, but damage to small blood vessels and nerves may contribute to changes in hearing.

Managing blood glucose levels and attending regular medical checkups can help reduce the risk of diabetes-related complications. If you notice changes in your hearing, discuss them with your healthcare provider.

Exposure to Loud Noises

Repeated exposure to loud noises can cause noise-induced hearing loss by damaging the delicate sensory hair cells in the inner ear. These cells help convert sound vibrations into electrical signals that the brain interprets as sound.

After attending a loud concert or event, you may notice temporarily muffled hearing or ringing in your ears. However, temporary symptoms can indicate that your ears have been exposed to potentially harmful sound levels. A single exposure to an extremely loud noise can also cause immediate hearing damage.

Damage to the sensory structures of the inner ear can be permanent. Noise exposure may also contribute to tinnitus, which causes ringing or other sounds in the ears. Other symptoms, such as dizziness, can occur depending on the type and severity of the injury.

Protect your hearing by limiting exposure to loud sounds, taking breaks in quieter environments, keeping personal audio devices at a safe volume, and using appropriate hearing protection when necessary.

Aging

Age-related hearing loss, medically known as presbycusis, is one of the most common causes of hearing difficulties. It typically develops gradually as changes occur in the inner ear and the auditory pathways involved in processing sound.

Age-related hearing loss can make conversations difficult to follow, particularly in noisy environments, and may affect your quality of life. Although it cannot usually be reversed, hearing aids and other hearing support options can help improve communication and make everyday listening easier.

Earwax

Excessive earwax buildup is a common and often treatable cause of hearing loss. When earwax accumulates and blocks the ear canal, it can prevent sound from reaching the eardrum effectively.

You may be able to manage minor earwax buildup with appropriate over-the-counter earwax-softening products, provided they are safe for you to use. However, significant blockages may require professional removal by a healthcare provider.

Avoid inserting your fingers, cotton swabs, or other objects into your ear canal. These can push earwax deeper and potentially injure the ear. Earwax-softening drops may help loosen the blockage, but they are not suitable for everyone, particularly people with a perforated eardrum, ear tubes, or certain ear conditions. Seek professional advice if you are unsure which treatment is appropriate.

Medications That Can Cause Hearing Loss

Some medications can damage the inner ear and cause hearing loss or other hearing-related symptoms. These medicines are sometimes called ototoxic medications. Depending on the drug, dosage, duration of use, and individual risk factors, the effects may be temporary or permanent.

Examples of medications that may affect hearing include:

  • Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs): High doses of aspirin and certain NSAIDs, including ibuprofen and naproxen, can sometimes cause ringing in the ears or temporary hearing changes.
  • Certain medications used to treat hypertension and heart failure: Loop diuretics, such as furosemide and bumetanide, may affect hearing in some circumstances, particularly at high doses or when combined with other risk factors.
  • Certain antibiotics: Aminoglycoside antibiotics can damage the inner ear and may cause permanent hearing loss. The risk depends on the specific medication and other clinical factors.
  • Cancer treatments: Some chemotherapy medicines, particularly cisplatin, can cause hearing damage. Other cancer treatments may also affect hearing, depending on the medication used.

Never stop taking a prescribed medication without consulting your healthcare provider. If you notice ringing in your ears, dizziness, or changes in hearing while taking medication, seek medical advice promptly.

Scarring of the Eardrum

Scarring of the eardrum, known as tympanosclerosis, can occur after repeated ear infections, inflammation, or other damage to the eardrum. In some cases, scarring can reduce the eardrum’s flexibility and interfere with the transmission of sound, potentially causing hearing loss.

The effect on hearing varies depending on the extent and location of the scarring. Some people experience little or no hearing difficulty, while others may require further evaluation or treatment. Surgery may be considered in selected cases, depending on the underlying problem.

A perforated eardrum is a different condition in which a hole or tear develops in the eardrum. It may cause hearing loss, ear pain, discharge, or tinnitus. Many perforations heal on their own over several weeks, although some require medical treatment or surgery.

When Should You Seek Help for Hearing Loss?

These are just some of the common causes of hearing loss. Certain risk factors, including smoking, exposure to loud noise, and some health conditions, may contribute to hearing difficulties. However, hearing loss can also occur for reasons unrelated to lifestyle.

If you notice changes in your hearing, consult a qualified hearing professional or healthcare provider. They can assess your hearing, help identify the underlying cause, and recommend appropriate treatment or hearing support.

Sudden hearing loss, especially in one ear, requires urgent medical evaluation. Do not delay seeking care, as prompt treatment may improve the chances of recovery.
