Hearing loss can be conductive (sound blocked before reaching the inner ear), sensorineural (inner ear or nerve damage), or mixed. Each type has different causes and treatments.
Conductive causes: Earwax buildup, ear infections, perforated eardrum, otosclerosis. Often treatable with medication, removal of blockage, or minor surgery.
Sensorineural causes: Ageing (presbycusis), noise exposure, certain medications, genetics. Usually permanent but can be managed with hearing aids or cochlear implants.
Signs to watch: Difficulty following conversations, turning up the TV, asking others to repeat, ringing in ears (tinnitus). Sudden hearing loss is a medical emergency.
When to see an ENT: Any sudden hearing loss, ear pain with discharge, dizziness with hearing changes, or gradual loss affecting daily life. Early intervention improves outcomes.
