23 Symptoms That Could Indicate Hyperthyroidism

16. Voice Changes or a Hoarse Throat

As the thyroid gland enlarges (goiter), it can start to press against nearby structures in the neck—including the voice box. This may cause subtle voice changes, hoarseness, or even a feeling like you constantly have to clear your throat. Some patients describe it as a "tightness" or “tickle” in the throat, even in the absence of a cold. If your voice sounds different or you find yourself frequently hoarse, your thyroid could be playing a bigger role than you realize.
