Common causes of hearing loss

Hearing loss is a complex condition with many causes. From age-related factors to external influences, it's important to understand the root cause. This not only helps address the issue, but also helps work out the best course of action

Common causes of hearing loss

  • Aging: As we grow older, our hearing can naturally decline
  • Loud noises: Prolonged exposure to loud noises can damage the inner ear
  • Genetic factors: Certain inherited conditions can make us more susceptible to hearing issues
  • Medications: Some drugs have side effects that can affect hearing
  • Acoustic neuroma: This is a non-cancerous growth that can impact the auditory nerve
  • Earwax build-up: Excessive earwax can block the ear canal, leading to temporary hearing loss
  • Infections and illnesses: Conditions like sinusitis can influence your hearing
  • Physical trauma: Injuries to the head or ear can result in hearing impairment
  • Lifestyle factors: Smoking, excessive alcohol consumption, and obesity can indirectly affect hearing
  • Foreign objects: Something as simple as an insect can block the ear canal
  • Other medical conditions: Diseases like tympanic effusion can affect hearing

Types of hearing loss explained

  • Sensorineural: This occurs due to damage to the inner ear or the nerve pathways to the brain. It can be present from birth or develop later in life
  • Conductive: Sound waves are obstructed in the outer or middle ear, preventing them from reaching the inner ear. Causes range from infections to damage to the middle ears bones (ossicles).
  • Mixed: A combination of both sensorineural and conductive hearing loss, affecting multiple parts of the ear
  • Noise-induced: Resulting from exposure to extremely loud sounds, this can be due to a single intense event or prolonged exposure
  • High-frequency: Struggling to hear sounds in the 2,000 to 8,000 Hertz range, often due to factors like aging, noise exposure, or genetics (FYI: Hertz measures the number of wave cycles (or frequency) passing through a given point in one second)
  • Unilateral: This affects only one ear, with the other ear functioning normally. It can be present from birth or develop later
  • Post-infection: An ear infection can lead to temporary or permanent hearing loss, especially if recurrent or untreated
