Does Levothyroxine cause a change in voice?
You need to repeat the thyroid function tests.
Hi dear user
I have gone through your question.
I can understand your concern.
A change in voice often means there is something amiss with the thyroid gland. Thyroid problems can lead to hormonal imbalances, which has a negative impact on the voice. Most commonly, deepening of the voice is reported.
In adults, hypothyroidism — an underactive thyroid — can be due to a variety of abnormalities, and lead to a deep hoarse voice.(You have a "breathy" voice so,in my opinion your function of thyroid gland must be evaluated carefully.
There are other thyroid problems that can be the culpit of voice changes.
Patients with thyroid problems may also hear a weakening of voice quality. If the thyroid gland or a growth on the thyroid is imposing on the recurrent laryngeal nerve, a vocal fold paralysis or paresis may result.
Patients with thyroid cancer may have the nerve destroyed, which is usually only on one side. This can lead to paralysis on one side of the larynx, so only one vocal cord is able to move. Voices will tend to come off as a whisper.
Hyperthyroidism may cause voice changes such as slight vocal instabilities, including "shaky" voice, breathy quality, and reduced loudness.
My advice is to consult an endocrinologist because you need to do the thyroid function test TSH, free T3 and free T4, to understand your actual thyroid function.After the test results your doctor will have the necessary information if your dose of Levothyroxine is right or need to be adjusted and to answer if is your thyroid that cause your voice change.
Hope I have answered your question. If you have any further questions I will be happy to help.
Thank you for using HCM.
Wish you good health.
