Many people are surprised to learn there’s a connection between hypothyroidism and hearing loss. If you’ve been diagnosed with an underactive thyroid—or are experiencing symptoms like fatigue, weight gain, or brain fog—you may also be at risk for hearing-related issues, including tinnitus (ringing in the ears).
The good news? With the right medical care and hearing treatment, many of these issues can be improved—and in some cases, even reversed.
What Is Hypothyroidism?
Hypothyroidism occurs when your thyroid gland doesn’t produce enough thyroid hormones. These hormones are essential for regulating metabolism, energy levels, and even the function of your nervous system, including the auditory system.
Common causes include autoimmune conditions like Hashimoto’s disease, the most common cause of hypothyroidism in the U.S.
Can Hypothyroidism Cause Hearing Loss?
Yes—research shows a clear link between hypothyroidism and hearing loss, particularly a type called sensorineural hearing loss, which affects the inner ear.
In fact:
- About 25% of people with hypothyroidism may have some degree of hearing loss
- Some studies suggest up to 40% may experience inner ear-related hearing issues
Why does this happen? Thyroid hormones play a critical role in the development and maintenance of the auditory system. When hormone levels are too low:
- Nerve function in the inner ear may be impaired
- Blood flow to the ear may be reduced
- Cellular processes that support hearing can be disrupted
This can lead to gradual hearing decline, often affecting higher-pitched sounds first.
The Link Between Hypothyroidism and Tinnitus
In addition to hearing loss, many people with hypothyroidism experience tinnitus—a ringing, buzzing, or hissing sound in the ears.
Research shows that people with thyroid disorders are more likely to develop tinnitus, and symptoms may worsen if thyroid levels are not well managed.
Why Tinnitus Occurs with Hypothyroidism
Thyroid hormone imbalances can disrupt nerve signaling and auditory processing, which may cause the brain to “fill in the gaps” with phantom sounds—what we perceive as tinnitus.
Can Hearing Loss from Hypothyroidism Be Reversed?
This is one of the most important, and encouraging, questions.
In some cases, yes.
Studies show that treating hypothyroidism with proper hormone replacement therapy can:
- Improve hearing in nearly 50% of patients
- Completely reverse hearing loss in about 15% of cases

Additionally, treating the underlying thyroid condition may reduce or eliminate tinnitus symptoms in some individuals.
However, not all hearing loss is fully reversible, especially if it has progressed over time. That’s why early diagnosis and treatment are so important.
Other Hearing Conditions Linked to Thyroid Disorders
Hypothyroidism, especially when caused by autoimmune conditions like Hashimoto’s, can increase the risk of other ear-related disorders, including:
- Autoimmune Inner Ear Disease (AIED): Can cause progressive hearing loss and tinnitus, sometimes reversible with early treatment
- Ménière’s Disease: Associated with vertigo, tinnitus, and fluctuating hearing loss
- Sudden Hearing Loss: More common in individuals over 50 with hypothyroidism
Why You Shouldn’t Ignore Hearing Changes
Many people don’t realize their hearing issues could be related to thyroid function. Unfortunately, this can delay treatment.
Common warning signs include:
- Ringing or buzzing in the ears
- Difficulty understanding speech (especially in noisy environments)
- Needing to increase volume on devices
- Feeling of fullness or pressure in the ears
- Dizziness or balance issues
If you have hypothyroidism and notice any of these symptoms, it’s important to take action.
The Importance of Treating Both Thyroid Health and Hearing Loss
Managing hypothyroidism is essential—not just for overall health, but for protecting your hearing.
Health experts recommend:
- Regular thyroid monitoring and medication management
- Hearing evaluations after a hypothyroidism diagnosis
- Ongoing hearing tests to track changes over time
Because hearing loss can develop gradually, early intervention can make a significant difference in long-term outcomes.
