Hearing Loss
Hearing loss ranges from mild difficulty following conversation to complete deafness in one or both ears. The inner ear, the auditory nerve, and the brain’s processing centres can all be involved, which is why causes and treatments differ widely.
Key points
- Fluctuating hearing loss paired with vertigo and ringing in the ears often points to a fluid-pressure problem in the inner ear.
- One inner-ear medicine targets local blood vessels and histamine activity to calm excess fluid build-up.
- Causes such as noise exposure, age-related decline or earwax blockage do not improve with medicine and need other approaches.
When the inner ear is the source
Most treatable forms of hearing loss in otherwise healthy adults trace back to the inner ear. Conditions such as Ménière’s disease cause fluctuating hearing loss alongside vertigo and tinnitus, due to abnormal fluid pressure in the cochlea. Betahistine acts on the inner-ear vasculature and histamine receptors to reduce this fluid build-up, which can stabilise hearing and lessen the frequency of dizzy episodes. It falls under neurology treatments rather than the surgical or audiological approaches used for permanent structural loss.
Other causes, such as noise damage, age-related loss (presbycusis), and earwax blockage, do not respond to drug treatment. If you notice sudden hearing loss in one ear, hearing loss after a head injury, or loss accompanied by severe pain or facial weakness, seek medical assessment promptly.
