January is National Thyroid Awareness month and as we approach the new year, it is good to educate yourself about the connection between hypothyroidism and hearing loss. There are many symptoms of thyroid disease and they can affect many of your body’s functions, including your hearing.
It is estimated that approximately 20 million Americans are living with some form of thyroid disease, but unfortunately as many as 60 percent are unaware of their condition. This is because many of the symptoms can stand alone as medical conditions or be comorbidities of other diseases. This can make it difficult to know one’s diagnosis.
Importance of Overall Health
The thyroid is a gland that produces hormones that regulate metabolism in the body. It sits below the Adam’s apple, along the front of the windpipe. Its shape is similar to a butterfly and undetectable to the touch when it is its normal size. When the thyroid does not produce enough of the hormone to regulate metabolism, many of the body’s functions slow down significantly.
When a condition of the thyroid is present, it can greatly affect the body’s essential functions including energy level, heart rate, central and peripheral nervous systems, body weight, and many others. Common conditions of the thyroid include:
- Hyperthyroidism occurs when the thyroid produces too much of the thyroxine hormone. Symptoms of hyperthyroidism include irritability, nervousness, muscle weakness, unexplained weight loss, sleep disturbances, vision problems, and eye irritation. It is not unheard of to experience tinnitus and/or vertigo while suffering from hypothyroidism.
- Hypothyroidism, however, occurs when the thyroid does not produce enough of this hormone. This can cause fatigue, depression, forgetfulness, and weight gain.
- Goiter is a condition wherein the thyroid swells and interferes with breathing and swallowing.
- Thyroid cancer is comparatively uncommon to other forms of cancer. Therefore, it usually responds well to treatment with surgery or radiation. The latter, however, could damage your hearing.
Your Ears and Your Thyroid
According to the Hearing Loss Association of America, about 48 million Americans have some degree of hearing loss (about 20 percent of the U.S. population) and roughly 40 percent of them are younger than 60.
Research is ongoing to find the connection between hearing loss and both hyperthyroidism and hypothyroidism, but they have both been linked to disabling hearing loss. The following thyroid conditions are known to affect not only hearing loss, but tinnitus and balance, as well:
- Pendred Syndrome, a genetic disorder that causes early hearing loss in children, also often leads to the development of goiter.
- Grave’s Disease, an autoimmune disorder wherein the immune system attacks the thyroid and causes it to produce more thyroid hormone than your body needs. It is one of the known causes of hyperthyroidism (an overactive thyroid).
- Hashimoto’s Disease, an autoimmune disorder that damages the thyroid gland. It is commonly known as a cause of hypothyroidism (an underactive thyroid).
Radiation treatment for thyroid cancer may cause hearing loss, as studies have shown that patients who undergo radiation treatment for cancers of the head or neck—like thyroid cancer—seem more likely to experience a hearing loss.
If you are experiencing symptoms connected with thyroid disease, consult your medical doctor and ask about the connections between thyroid disease and hearing loss. You should also consult a hearing health care professional to learn how to navigate your hearing health during treatment. Hearing health should not be overlooked when considering your overall health. Better care and attention to your overall health will ultimately benefit your hearing.
