A voice disorder results in changes to the voice such as hoarseness, raspiness, and/or a change in pitch. A complete loss of the voice can also occur. Many things we do can injure our vocal cords and cause a voice disorder. Some examples of vocal abuse or misuse might be talking too much, screaming, constantly clearing your throat, or even smoking. They can also lead to problems such as nodules, polyps, and sores on the vocal cords. Other causes of voice disorders include infections, acid reflux, growths due to a virus, cancer, and diseases that paralyze the vocal cords.
Any change in the movement of the vocal cords can impact the quality of the voice, but also communication with others.
