Tinnitus
Perception of ringing or buzzing sounds in the ears.
TL;DR
Tinnitus is usually the sound of a damaged hearing system being amplified by the brain. It is rarely dangerous, but new one-sided, pulsating or sudden tinnitus needs prompt assessment. No supplement has convincing evidence — ginkgo biloba failed in large trials, and zinc only helps in the deficient. The most effective approaches are sound therapy, hearing aids where hearing loss coexists, and cognitive behavioural therapy, which reliably reduces distress even when the sound itself persists.
Overview
Tinnitus — the perception of ringing, buzzing, hissing or humming without an external sound — affects around one in seven adults and becomes more common with age. For most people it is a nuisance that fades into the background; for roughly one in five of those affected it is persistent and distressing, disrupting sleep, concentration and mood. Tinnitus is a symptom, not a disease: it usually reflects hearing damage, but the brain's amplification of the signal — not the ear itself — determines how intrusive it becomes.
Common Symptoms
- •Ringing, buzzing, hissing, clicking or humming without external source
- •Sound heard in one ear, both ears, or inside the head
- •Worse in quiet environments and at night
- •Difficulty concentrating or sleeping
- •Increased awareness during stress or fatigue
- •Occasional associated sound sensitivity or ear fullness
Common Causes
- •Noise-induced hearing damage — the leading cause
- •Age-related hearing loss
- •Earwax blockage or ear infection
- •Meniere's disease — tinnitus with vertigo and fluctuating hearing
- •Medications — high-dose aspirin, some antibiotics, loop diuretics, some antidepressants
- •Head or neck injury
- •Temporomandibular joint disorder
- •Cardiovascular causes when the sound pulses with the heartbeat
Root Causes
Most tinnitus begins with damage to cochlear hair cells from noise or ageing, which reduces the ear's output to the brain. Auditory brain regions respond by turning up their gain — like an amplifier compensating for a weak signal — and this neural overactivity is perceived as sound. Attention and emotional networks then determine intrusiveness: tinnitus linked to threat and monitored constantly stays loud in perception, while tinnitus that is habituated fades from awareness. This is why treatment targets reaction as much as the sound itself.
How It's Diagnosed
Diagnostic Markers
- Pure tone audiogram — the essential first test, often revealing unsuspected hearing loss
- Tympanometry to assess middle-ear function
- Unilateral tinnitus — MRI to exclude vestibular schwannoma where indicated
- Pulsatile tinnitus — blood pressure check and vascular assessment
- Medication review for ototoxic drugs
- THI (Tinnitus Handicap Inventory) to quantify impact
When to See a Doctor
{"Tinnitus in only one ear","Tinnitus that pulses in time with your heartbeat","Sudden onset, especially with sudden hearing loss — same-day emergency","Tinnitus with vertigo, ear fullness or fluctuating hearing","Tinnitus following head injury","Any tinnitus significantly disrupting sleep or mood"}
Supplements Studied For This
Zinc
Insufficient evidence. No benefit in unselected patients; possible role only in documented deficiency.
Ginkgo Biloba
No. Large randomised trials and Cochrane review show no benefit for tinnitus.
Diet & Lifestyle
Suggested Pattern
No diet has been shown to treat tinnitus. Caffeine restriction is commonly advised but trial evidence suggests caffeine does not worsen tinnitus and abrupt withdrawal may temporarily aggravate it. High sodium intake is worth moderating in Meniere's disease specifically. Overall cardiovascular health matters where tinnitus is pulsatile.
Eat more
- A generally cardioprotective diet — vascular health supports cochlear blood flow
- Adequate B12-rich foods where intake is low — deficiency is associated with tinnitus
- Zinc-rich foods — shellfish, meat, legumes — particularly in older adults
- Potassium-rich foods for inner-ear fluid balance
- Adequate hydration
Avoid
- Very high sodium intake where Meniere's disease is diagnosed
- Excess alcohol — dilates vessels and can transiently worsen perception
- High-dose aspirin — directly ototoxic at large doses
- Nicotine — reduces cochlear blood flow

Frequently Asked Questions
Who It Affects
Around 15% of adults experience tinnitus, rising to a quarter of those over 65. About 20% of those affected find it significantly bothersome, and 1-2% of the population have severe, disabling tinnitus.
Most common in older adults, in people with occupational or recreational noise exposure, in military veterans, and in those with hearing loss. Distress correlates more with anxiety and sleep quality than with the loudness of the sound itself.
Quick Facts
- •Affects roughly 15% of adults; rises sharply with age
- •One-sided or pulsatile tinnitus warrants prompt medical review
- •No supplement has replicated benefit in high-quality trials
- •Hearing loss is the most common underlying driver
- •CBT is the most effective treatment for tinnitus distress
- •Silence makes tinnitus louder — background sound is therapeutic
Lifestyle Tips
- •Get a hearing test — hearing aids reduce tinnitus perception in most with hearing loss
- •Avoid silence: low background sound, fans or sound apps take the edge off
- •Protect remaining hearing — earplugs at concerts and around loud machinery
- •Do not monitor the sound — checking on it maintains the brain's attention loop
- •Manage sleep and stress — both reliably amplify perceived loudness
- •Ask about CBT-based tinnitus programmes if distress is significant
