Hearing Loss: Types, Causes and When It's Urgent

Hearing loss affects quality of life and mental health significantly. Identifying the type — conductive versus sensorineural — determines the cause and best treatment.

Prevalence
1 in 6 UK adults
Most common cause (adults)
Age-related (presbyacusis)
Sudden SNHL
Emergency — steroids within 72 hours
Hearing aids
Underused — only 40% of those who need them wear one
Sudden Hearing Loss Is an EmergencySudden sensorineural hearing loss (SSNHL) — hearing loss appearing within 72 hours, especially in one ear — should be treated with high-dose oral steroids (prednisolone 1 mg/kg) within 72 hours of onset. Delay reduces recovery chances. Same-day ENT referral.

Conductive vs Sensorineural

ConductiveSound blocked before inner earEarwax, otitis media, perforated eardrum, otosclerosisRemove cause; surgery if otosclerosis
Sensorineural (SNHL)Cochlear hair cell or nerve damageAge-related (presbyacusis), noise exposure, Ménière's, ototoxic drugsHearing aids; cochlear implant for severe

Age-Related Hearing Loss (Presbyacusis)

Simple Earwax Test FirstEarwax is a common, easily treatable cause of conductive hearing loss. Ear drops (olive oil or proprietary softeners) daily for 2 weeks often resolve mild cases. Irrigation or microsuction at the GP practice or pharmacy removes stubborn wax.
How do I know if I need a hearing aid?
If you regularly ask people to repeat themselves, struggle on the phone, turn up the TV volume, or miss parts of conversations — you likely have hearing loss that would benefit from a hearing aid. Start with an NHS audiology referral.
What are ototoxic drugs?
Medications that damage cochlear hair cells: aminoglycoside antibiotics (gentamicin), cisplatin and other platinum chemotherapy agents, high-dose loop diuretics (furosemide), aspirin in toxic doses, quinine. Monitor hearing during treatment.
Can I get a hearing aid on the NHS?
Yes — NHS hearing aids are free for people with hearing loss confirmed by audiology. Modern NHS digital hearing aids are comparable to many private devices. There may be a waiting list — private audiology can be faster.
What is Ménière's disease?
A disorder of the inner ear causing episodic vertigo (lasting 20 minutes to 24 hours), fluctuating low-frequency sensorineural hearing loss, tinnitus, and ear fullness. Managed with dietary salt restriction, diuretics, betahistine, and in severe cases, intratympanic gentamicin or surgery.
