Can hypothyroidism cause ringing in the ears?

Yes, evidence suggests that hypothyroidism, or an underactive thyroid, can result in a ringing in the ears, also known as tinnitus. Scientists believe this is due to the impact hypothyroidism can have on hormone levels, but more research is still necessary.

With hypothyroidism, the thyroid does not produce enough hormones, which can disrupt the balance of chemicals and signals in the body. Thyroid hormones play an important role in maintaining the health of nerves, including those in the ears.

Thyroid hormones are essential for the development of the auditory system. These hormones help regulate proteins and enzymes responsible for the structure of the inner ear, which is crucial for hearing. As such, a deficiency in thyroid hormones may lead to tinnitus.

There are many potential signs and symptoms of hypothyroidism. They may develop slowly over a long period, meaning a person may not notice them or relate them to growing older.

Symptoms relating to the ear that can suggest hypothyroidism include:

• tinnitus
• noises in the ears, such as hissing
• hearing loss
• balance and coordination problems
• dizziness
• vertigo

Evidence also highlights that other thyroid problems, such as hyperthyroidism, or an overactive thyroid, can also result in tinnitus. As such, more research is necessary to understand the mechanisms linking thyroid hormones and tinnitus.

Treating hypothyroidism may help to relieve ringing in the ears. Typically, treatment will involve replacing the hormone the thyroid is no longer producing to restore hormone levels. As such, a doctor may prescribe levothyroxine, which is a synthetic version of the thyroid hormone thyroxine.

Treatment options for tinnitus can include:

• sound therapies
• behavioral therapy
• certain medications, such as antidepressants or anti-anxiety medications
