Tinnitus is the perception of sound in the absence of an external noise source. It can vary in pitch and intensity and frequently manifests as ringing, buzzing, hissing, or humming in the ears. Tinnitus is a symptom of an underlying ailment rather than a sickness in and of itself. While it may come and go for some people, for others it can become chronic and severely impact quality of life.
Understanding what causes tinnitus—and the diseases most commonly associated with it—can help patients and healthcare providers find the most effective ways to manage and treat it.
What Is Tinnitus?
The most typical description of tinnitus is “ringing in the ears,” however a variety of phantom noises are often reported. It can be subjective (only the person can hear it) or objective (rarely, others can hear it with a stethoscope near the ear).
Subjective tinnitus is the most prevalent kind. Numerous factors, such as hearing loss, illnesses, neurological problems, trauma, infections, and even stress, can cause it.
Let’s explore the main diseases and medical issues that are commonly associated with tinnitus.
1. Hearing Loss
How It Causes Tinnitus:
Age-related hearing loss (presbycusis) and noise-induced hearing loss are two of the most common causes of tinnitus. When the tiny hair cells in the inner ear become damaged—due to aging or exposure to loud noise—the brain receives less input from the auditory system. This lack of stimulation can trigger abnormal neural activity that the brain interprets as sound.
Treatment Options:
- Hearing aids: Reduce the prominence of tinnitus by amplifying outside noises.
- Sound therapy: Uses background noise or white noise to mask tinnitus.
- Cognitive Behavioral Therapy (CBT): Helps patients cope with the psychological effects.
2. Meniere’s Disease
How It Causes Tinnitus:
Meniere’s disease is an inner ear condition that impairs hearing and balance. Unusual fluid accumulation in the inner ear chambers results in pressure fluctuations that can cause vertigo, tinnitus, and hearing loss.
Treatment Options:
- Diuretics: Help reduce fluid buildup.
- Low-sodium diet: Prevents fluid retention.
- Vestibular therapy: Improves balance.
- Surgical intervention: In severe cases.
3. Temporomandibular Joint Disorders (TMJ)
How It Causes Tinnitus:
The jawbone and skull are joined by the temporomandibular joint, which is situated close to the ear canal. Dysfunction or inflammation in this joint can affect nearby auditory nerves and muscles, resulting in tinnitus.
Treatment Options:
- Dental splints or mouth guards: To prevent teeth grinding.
- Physical therapy: To improve jaw alignment.
- Anti-inflammatory medications: To reduce joint swelling.
- Botox injections: In severe muscle tension cases.
4. Acoustic Neuroma
How It Causes Tinnitus:
A benign growth called an acoustic neuroma develops on the vestibular nerve, which connects the brain and inner ear. It may put pressure on the cochlear nerve, which is in charge of hearing, resulting in tinnitus, hearing loss, and issues with balance.
Treatment Options:
- Monitoring: Small tumors may only require observation.
- Radiation therapy: To shrink or stop tumor growth.
- Surgical removal: In larger or fast-growing cases.
5. Ear Infections and Blockages
How It Causes Tinnitus:
Ear infections (otitis media or externa), wax buildup, or a foreign object in the ear can interfere with normal sound transmission and irritate the auditory system. This can lead to temporary tinnitus.
Treatment Options:
- Ear drops or antibiotics: To treat infections.
- Ear irrigation or manual removal: For wax or debris.
- Addressing allergies or sinus problems: To reduce inflammation.
6. High Blood Pressure and Cardiovascular Diseases
How It Causes Tinnitus:
Pulsatile tinnitus is a form of tinnitus where a rhythmic pulsing is heard in sync with the heartbeat. Due to vascular abnormalities, atherosclerosis, or high blood pressure, it is frequently associated with elevated or turbulent blood flow in the vicinity of the ears.
Treatment Options:
- Blood pressure control: Through lifestyle changes and medication.
- Surgical correction: For vascular malformations.
- Stress management: As stress contributes to high blood pressure.
7. Otosclerosis
How It Causes Tinnitus:
Otosclerosis is the abnormal growth of bone in the middle ear, typically around the stapes bone, which interferes with sound transmission. This can lead to hearing loss and accompanying tinnitus.
Treatment Options:
- Hearing aids: To improve hearing and reduce tinnitus perception.
- Stapedectomy: replacing the stapes bone with surgery.
8. Multiple Sclerosis (MS)
How It Causes Tinnitus:
MS is a neurological disease that damages the protective myelin sheath around nerves, including the auditory nerve. Tinnitus and other auditory hallucinations may be brought on by this interference in signal transmission.
Treatment Options:
- MS management: Steroids, immunosuppressants, and lifestyle adjustments.
- Tinnitus therapies: Sound therapy, CBT, and hearing aids if needed.
9. Thyroid Disease
How It Causes Tinnitus:
Both hypothyroidism and hyperthyroidism can contribute to tinnitus. Imbalances in thyroid hormones may affect blood flow, energy metabolism in auditory cells, and nerve function.
Treatment Options:
- Thyroid hormone therapy: To restore balance.
- Dietary changes and monitoring: To support thyroid function.
- Tinnitus-specific treatments: If symptoms persist.
10. Anemia and Iron Deficiency
How It Causes Tinnitus:
Anemia reduces the oxygen supply to tissues, including those in the auditory system. The lack of oxygen can impair cellular function and lead to ringing in the ears. In some cases, increased cardiac output from anemia causes pulsatile tinnitus.
Treatment Options:
- Iron supplements: For iron deficiency anemia.
- Dietary changes: Include iron-rich foods like red meat, spinach, and legumes.
- Treat underlying conditions: Like gastrointestinal bleeding.
11. Diabetes
How It Causes Tinnitus:
Diabetes can cause nerve damage (neuropathy), and high blood sugar levels may damage blood vessels that supply the inner ear, leading to hearing loss and tinnitus.
Treatment Options:
- Blood sugar control: Essential to prevent further damage.
- Diet and exercise: Help manage glucose levels.
- Tinnitus management tools: Including sound therapy and stress relief.
General Approaches to Tinnitus Treatment
While treating the underlying cause is the most effective strategy, some forms of tinnitus may persist even after the root condition is addressed. In these cases, managing symptoms becomes the focus.
1. Sound Therapy
Involves introducing background noise (white noise, nature sounds, soft music) to make tinnitus less noticeable. It’s often delivered through:
- Hearing aids with built-in sound generators
- White noise machines
- Tinnitus masking apps
2. Cognitive Behavioral Therapy (CBT)
CBT is one of the most effective psychological approaches for tinnitus. It helps change the emotional response to tinnitus, reducing distress and anxiety.
3. Tinnitus Retraining Therapy (TRT)
TRT combines sound therapy with counseling to habituate the brain to the tinnitus sound, gradually making it less intrusive.
4. Medications
Although no drug cures tinnitus, certain medications can ease associated symptoms:
- Antidepressants: For anxiety and depression.
- Anti-anxiety drugs: To calm nervous system activity.
- Sleep aids: To improve rest and reduce fatigue.
5. Lifestyle Modifications
- Avoid loud environments: To protect remaining hearing.
- Limit caffeine, alcohol, and nicotine: Which can aggravate symptoms.
- Practice mindfulness and meditation: To manage stress and reactivity.
- Regular exercise: Boosts circulation and reduces stress hormones.
When to See a Doctor
Tinnitus can occasionally be a sign of a more serious condition. Immediate medical attention is recommended if:
- Tinnitus is sudden or comes with sudden hearing loss.
- You experience dizziness, vertigo, or balance issues.
- The sound is pulsatile (in sync with your heartbeat).
- Tinnitus occurs in only one ear.
- It interferes with your daily life or sleep.
Conclusion
Tinnitus is a complex and often misunderstood condition, with a wide range of causes from simple earwax blockages to complex neurological or cardiovascular disorders. While it can be a chronic and distressing symptom, it is often manageable—especially when the underlying disease is properly diagnosed and treated.
Advances in hearing technology, sound therapy, psychological treatments, and medical interventions have made it possible for many people to find significant relief. Understanding the diseases linked to tinnitus is the first step toward a quieter, more comfortable life.
Whether your tinnitus is mild or severe, persistent or occasional, getting a comprehensive medical evaluation and following an individualized treatment plan is key to regaining control over your auditory health.
