4Addressing Modifiable Factors

FStart with what can be changed

Tinnitus rarely arrives in isolation. It usually sits on top of a hearing system that has been stressed by noise, by drugs, by an untreated ear condition, or by a body that is exhausted and anxious. Many of these contributors are modifiable, and addressing them is the cheapest, safest and most logical first move in management — long before sound therapy or medication is considered.

The principle is simple: remove or treat the aggravators, give the auditory system the best possible input, and a proportion of patients will find their tinnitus quieter, more stable, or simply less intrusive. Even when the sound itself does not change, taking visible action on the things a patient can control restores a sense of agency that is therapeutic in its own right [2014].

FNoise exposure and hearing protection

Excessive noise is both a cause of the underlying hearing loss and a frequent trigger for transient worsening of tinnitus. Recreational and occupational noise — power tools, concerts, firearms, industrial machinery — should be identified in the history and reduced where possible.

Patients are counselled to use well-fitted hearing protection (foam plugs, custom musician’s plugs, or earmuffs) in loud environments, and to observe the practical rule that if you must raise your voice to be heard at arm’s length, the environment is too loud. Importantly, patients should be reassured against the opposite error: prolonged over-protection and silence-seeking can heighten attention to the tinnitus and worsen any co-existing hyperacusis [2021].

TReviewing ototoxic and tinnitus-inducing drugs

A medication review is one of the highest-yield steps in a tinnitus work-up. A large number of widely used drugs can induce or aggravate tinnitus — classically high-dose aspirin and other NSAIDs, aminoglycoside and some macrolide antibiotics, loop diuretics (furosemide), platinum chemotherapy (cisplatin, carboplatin), and antimalarials such as quinine and hydroxychloroquine [2011].

The reaction pattern differs by mechanism. Salicylate- and quinine-induced tinnitus is typically dose-dependent and reversible on stopping the drug, whereas aminoglycoside and platinum ototoxicity is often permanent. Other agents — some SSRIs, antiepileptics, ACE inhibitors and beta-blockers — are reported more variably, and tinnitus can also emerge during antidepressant withdrawal. The clinician should cross-check the full drug list, including over-the-counter analgesics, and discuss dose reduction or substitution with the prescriber where a temporal link is plausible. Stopping medication should never be done unilaterally if the drug is treating a serious condition.

TCaffeine, alcohol, nicotine and the lifestyle question

Patients very commonly ask whether cutting out coffee will help. The honest answer is that the evidence is weaker than the folklore. A triple-blind randomised crossover trial found that caffeine did not significantly change tinnitus loudness or annoyance, arguing against blanket caffeine restriction — and abrupt caffeine withdrawal can itself provoke headache and irritability that make tinnitus feel worse [2021].

Population data are more nuanced for other exposures: smoking and heavy alcohol intake are associated with a higher burden of tinnitus and of the hearing loss that underlies it [2021]. The pragmatic message is to encourage smoking cessation and moderation of alcohol on general health grounds, to let patients run their own short, reversible experiment with any suspected dietary trigger, and to avoid imposing joyless restrictions that are not supported by data.

CStress, sleep and the underlying ear

Stress and poor sleep do not create tinnitus, but they powerfully modulate how loud and how threatening it feels, through limbic and attentional amplification. Sleep deprivation in particular sets up a vicious circle: tinnitus disturbs sleep, and the resulting fatigue heightens tinnitus salience the next day. Sleep hygiene, low-level bedside sound enrichment, and treatment of any frank insomnia or mood disorder are therefore core — not optional — parts of modifiable-factor management [2013].

Finally, the underlying ear must not be forgotten. Impacted cerumen, otitis media with effusion, otosclerosis, and especially uncorrected sensorineural hearing loss are all modifiable inputs. Treating the ear disease — and, where there is hearing loss, restoring auditory input with amplification — is frequently the single most effective conservative measure, and is the subject of the next module [2014].
