Laryngitis is an inflammation of the voice box, or larynx, that causes your voice to become raspy or hoarse.
Laryngitis can be short-term or long-lasting (chronic). Most of the time, it comes on quickly and lasts no more than 2 weeks.
Chronic symptoms are those that last 2 weeks or longer. Check with your doctor if your symptoms last more than 2 weeks, because your laryngitis may be caused by more severe problems.
What causes laryngitis?
Laryngitis can be caused by:
- Colds or flu. This is the most common cause.
- Acid reflux also known as gastroesophageal reflux disease (GERD). This type of laryngitis is also called reflux laryngitis.
- Overuse of your voice, such as cheering at a sports event.
- Irritation, such as from allergies or smoke.
