What causes hoarse voice?
Misuse of the voice, such as prolonged talking or shouting, is a common cause of hoarse voice. Other possible causes include tobacco use, marijuana use, and exposure to chemicals—even those found in some household cleansers—or pollutants.
Hoarse voice can also be a result of allergies, inflammation, colds, flu, or reflux disorders (regurgitation of stomach acids and digestive enzymes up into the throat) and, in some cases, neurologic disorders, thyroid or hormonal disorders, or laryngeal cancer.

Questions for diagnosing the cause of hoarse voice
To diagnose your condition, your doctor or licensed health care practitioner will ask you several questions related to your hoarse voice including:
- How long have you had a hoarse voice?
- Do you recall straining your voice recently?
- Does your throat feel painful or dry?

What are the potential complications of hoarse voice?
Left untreated, a chronically misused or overused larynx, the most common cause of hoarse voice, can lead to thickening and calluses on the surfaces of the vocal folds. Because hoarse voice can be due to serious diseases, failure to seek treatment can result in serious complications and permanent damage. Once the underlying cause is diagnosed, many of these complications can be avoided. For that reason, it is important for you to follow the treatment plan that you and your health care professional design specifically for you to reduce the risk of potential complications including:
- Inflammation due to continual irritation
- Loss of or permanent damage to voice
- Spread of cancer
- Spread of infection
